First Aid: Espresso Machines — Solve Problems Yourself

← Back to the first-aid overview

Most “defects” aren't defects at all — in roughly 80% of cases it's a setting or a bit of care that you can fix yourself in a few minutes. Here are the most common problems with espresso machines, with safe steps that follow manufacturer guidance. And if it really is the machine, we'll tell you honestly where the line is.

1. “My espresso runs through too fast and tastes sour — or only drips out and tastes bitter”

Applies to all brands — and is almost never a defect, but rather grind size and dose.

Try this first:

1. Base it on weight: ratio 1:2 — e.g. 18 g in, 36 g out, on the scale. We extract by weight, never by time — taste decides.
2. Tastes sour/thin: grind finer. Bitter/harsh: grind coarser.
3. Change only one variable per shot.
4. Weigh the dose — eyeballing it varies more than you'd think.
5. Check the shower screen for coffee residue and rinse it.

Stop line: Do not adjust the pump pressure or the expansion valve.

2. “The machine is scaled up — less water flow, takes forever to heat”

The classic Swiss issue: in many municipalities, hard water comes out of the tap.

Try this first:

1. Measure your water hardness (test strips) or look it up for your municipality.
2. Prevent rather than descale: a tank filter (e.g. Brita) or treated water — La Marzocco recommends ~90–150 ppm TDS.
3. La Marzocco Home: drain the steam boiler regularly (an approved routine).
4. Don't descale on your own: La Marzocco doesn't provide for DIY descaling — water damage isn't covered by warranty. Profitec also advises against running descaler through the machine. A scaled-up machine = service.

Stop line: Never pump descaling solution through the boiler or group head. Never open the boiler.

3. “When pulling a shot, water sprays out sideways from the portafilter”

Try this first:

1. Clean the gasket rim and shower screen with the brush.
2. Lock the portafilter in more firmly, test again.
3. Still leaking: replace the group gasket and shower screen — La Marzocco recommends replacing them every 6–12 months; Profitec names this exact symptom as the signal to replace them.
4. Fit the new gasket dry, tighten hand-tight.

Stop line: Do not disassemble the E61 group, no force on stuck screws.

4. “No or too little steam — the milk won't foam”

Try this first:

1. Purge the wand briefly right after every use and wipe it while damp.
2. Unscrew the tip and clear the holes with a needle and warm water.
3. Use a milk system cleaner.
4. Single-circuit machine: really wait out the switch-over and heat-up time.
5. Still weak? Check the water hardness (problem 2) — limescale in the steam path is a service case.

Stop line: The steam, anti-vacuum, and safety valves are off-limits.

5. “The espresso suddenly tastes musty or rancid — despite good beans”

Almost always: coffee-oil buildup in the group and shower screen.

Try this first:

1. Backflush with a blind basket: briefly every day with plain water, no detergent, plus roughly every 50 shots with a coffee-oil remover (detergent, about 5 minutes). Only on machines with a 3-way valve (check the manufacturer's instructions)!
2. Run several short cycles until the foam comes out white, then rinse thoroughly with water.
3. Soak baskets and portafilters in cleaning solution.
4. Remove the shower screen and clean it.
5. Victoria Arduino: run the guided cleaning cycle per the Quick Guide.

Sources: La Marzocco — Clean Guide · Victoria Arduino — E1 Prima Quick Guide (PDF) · Urnex — How to Backflush (instructional video)

Stop line: No citric acid or home remedies through the group.

Gear: blind basket & brushes from the cleaning collection · Oil remover: Urnex Cafiza (the industry standard for backflushing)

6. “The E61 group keeps dripping”

From our everyday service work — manufacturers rarely document this publicly:

1. Context: a few individual drops during the heat-up phase are normal by design (the expansion valve is working).
2. Backflush with cleaner (problem 5) — the dripping often disappears afterward.
3. Clean or replace the shower screen and gasket.
4. If it keeps dripping continuously: a group overhaul at the service center — that's workshop work.

Stop line: Do not adjust or open the expansion/overpressure valve yourself.

Gear: blind basket from the cleaning collection · Oil remover: Urnex Cafiza · Request service

7. “The pump rattles loudly, but no water comes out”

Usually air in the system — typical after the tank has run dry:

1. Fill the tank and seat it correctly, check the intake tube for kinks.
2. Without the portafilter, draw water through the group until it runs bubble-free (bleed per the manual).
3. Briefly open the hot water or steam valve — that helps the priming.
4. Clean the tank strainer/inlet filter.
5. If the pump stays dry and loud: switch it off immediately (pump protection) and contact service.

Stop line: Do not remove the pump or wiring, do not adjust the pump pressure, never let it run dry.

8. “The first shot is scalding hot — the temperature fluctuates” (heat exchanger machine)

1. Cooling flush: before the first shot, briefly run water through the group until the spitting and steaming stop.
2. Observe the heat-up time — an E61 group (heat exchanger machine) needs roughly 20 minutes to warm through.
3. PID models: keep the brew temperature within the recommended window of 88–95 °C (Profitec factory setting).
4. Still off no matter what? Service.

Source: Profitec — Service/FAQ

Stop line: Do not adjust the pressure switch or thermostat.

9. “Lever machine (Flair, Superkop, Aram): no pressure — or water pushes out sideways”

1. Grind finer — according to Flair, the most common fix.
2. Increase the dose, or on the Flair 58 use the low-flow basket.
3. A real leak: check the O-rings and piston seal and replace them exactly per the manufacturer's instructions (Superkop PDFs, Flair spare parts).
4. Care for gaskets with food-safe grease.
5. Aram: check assembly and process against the official manual.

Stop line: The Superkop gas spring only exactly per the manufacturer PDF; do not open the pressure gauge.

Spare parts: Flair · Superkop · Aram

10. “Wacaco on the road: barely any pressure, thin coffee, leaking”

1. Check the grind size: fine like table salt — too coarse gives no pressure, too fine blocks it. Nanopresso: 8 g dose.
2. Hot water (90–96 °C) and preheat the device.
3. Tighten the basket head firmly, keep the dose exact.
4. Pump steadily, about one pump stroke per second.
5. Rinse after every use; deep-clean the gasket monthly, the metal mesh every 6–12 months.

Sources: Wacaco — FAQ · Wacaco — Manuals · Video: Wacaco — Picopresso Cleaning (official channel)

Stop line: Do not disassemble the pump mechanism; never open a hot device under pressure.

Gear: Outdoor & travel equipment

11. “The machine won't heat at all anymore — stays completely cold”

Self-help is deliberately short here — this is usually a service case:

1. Test the outlet and fuse with another device.
2. Insert the water tank correctly — many machines block the heater without a tank signal.
3. Let it cool unplugged for 30 minutes, then try a restart.
4. No improvement? Service. A common cause is a triggered over-temperature protection after limescale or dry running — have the cause fixed at the same time.

Absolute limit: Opening the housing, electrics, heating element, thermostat reset, boiler — all workshop-only.

Request service & repairs

12. “The Eversys super-automatic reports a cleaning prompt or an error” (commercial)

1. Run the guided cleaning cycles on the display (tabs/milk cleaner as specified).
2. Remove the steam nozzle monthly and clean it with mild soap and a brush (official Eversys instructions).
3. Note the error code and contact us as your service partner.

Error code overview: If your display shows an error code starting with “E-”, in these four cases you can often check for yourself before contacting service:

For all other E-codes (including the range E-003 to E-107, e.g. motor, heating, or pressure-sensor faults), Eversys itself recommends not intervening further yourself, but contacting the service organization directly.

Stop line: Everything beyond the guided cleaning (brewer removal, boiler, electrics) belongs to the technician.

La Marzocco Leva X

Mechanically, the Leva X is a different animal from the other espresso machines in our lineup: brew pressure doesn't come from a pump, but from a spring that you tension via the lever and release under control. A digital display tracks your shot's pressure/time curve live. Precisely because of this different mechanism, its own safety rules apply here — read them through calmly before you get to work yourself.

13. “When backflushing, there's a loud bang when I let go of the lever — is that bad?”

Yes, that's an operating mistake you should avoid from now on: while backflushing, the lever must never be released without counter-pressure — it has to be guided under control until the water runs clear.

1. Guide the lever back slowly and by hand while backflushing, never just let go.
2. Only let go once you no longer feel any counter-pressure on the lever.
3. Repeat the process until the water running through is clear.

Source: La Marzocco — Leva X 1GR Manual

Stop line: The manufacturer explicitly warns against releasing the lever while backflushing — it can cause structural damage to the machine. If this has already happened to you, or the lever has felt different since, get in touch with us instead of testing further.

14. “The lever is hard to pull — is my spring broken?”

A noticeable amount of force is fundamentally part of using a spring-lever machine — according to La Marzocco, the Leva X needs roughly 40% less force than other lever machines on the market, but some resistance remains part of the design.

1. Compare the feel to your first impression at handover or first use — slight variation from shot to shot is normal, since you build the pressure yourself.
2. If there's a clear, lasting deterioration, don't start adjusting the spring or preload yourself.

Source: La Marzocco — Leva X1 product page

Stop line: For the Leva X 1GR's spring tension, there's currently no manufacturer self-adjustment procedure that we've confirmed. Please don't tinker with the spring on a hunch — get in touch with us or directly with La-Marzocco service.

15. “The shot runs unevenly or the coffee suddenly tastes different”

Usually a dirty diffuser screen or a dirty piston underside is behind it — on the Leva X, this cleaning is recommended daily.

1. Remove the diffuser screen with the tool provided.
2. Clean with coffee-cleaning powder and rinse thoroughly.
3. When reinstalling, make sure the spring clicks audibly into place.
4. Then operate the group several times to flush it through.

Source: La Marzocco — Leva X 1GR Manual

Stop line: If the spring doesn't click audibly into place on reinstallation, or the diffuser screen won't fit cleanly, don't force it — get in touch with us.

16. “The portafilter is hard or dangerous to remove after the shot”

This is usually residual pressure in the system — the Leva X releases pressure differently than our pump machines; there's no automatic pressure release.

1. Never remove the portafilter while the gauge still reads above zero.
2. Use the lever to lift the piston slightly to release the counter-pressure.
3. Only remove the portafilter afterward.

Source: La Marzocco — Leva X 1GR Manual

Stop line: This is a hard safety limit, not a judgment call: removing the portafilter under residual pressure can cause scalding. If in doubt, wait until the gauge genuinely reads zero.

17. “The boiler pressure rises sharply while heating up — is that normal?”

Yes, up to a certain threshold that's normal heat-up behavior: the Leva X's coffee boiler is limited to a maximum of 6 bar via an expansion valve behind the drip tray.

1. Wait out the heat-up phase without intervening.
2. Keep an eye on the gauge, but don't readjust it yourself.

Source: La Marzocco — Leva X 1GR Manual

Stop line: Water as hot as up to 93°C sits at the expansion valve — adjustment or disassembly is exclusively a job for a specialist, don't open it yourself.

La Marzocco Linea Micra

The Linea Micra is our most compact La-Marzocco dual boiler for home use, and it's controlled via an app — you set the steam and brew water temperature there. From the factory it comes with a water reservoir, and on request also with a plumbed-in connection (its own kit, not interchangeable with the kit for the Linea Mini/GS3).

18. “The steam wand barely has any pressure, the milk won't foam”

Usually it's residue in the wand or the steam-pressure setting in the app.

1. Clean the steam wand with a damp cloth immediately after every use.
2. Check the steam pressure in the app — around 1.8 bar from the factory, adjustable in the range 1.3–2 bar.

Source: La Marzocco — Linea Micra Manual

Stop line: Don't touch the steam wand for at least 40 seconds after steaming, and don't open the steam boiler yourself.

19. “The gauge shows up to 12 bar while heating up — is something broken?”

No: that's normal heat-up behavior for the Micra. The actual shot happens at around 9 bar.

1. Wait out the heat-up phase without intervening.
2. During the actual shot, check whether the pressure settles into the usual range around 9 bar.

Source: La Marzocco — Linea Micra Manual

Stop line: The gauge and steam boiler aren't for DIY adjustment. If the pressure consistently seems different than usual, talk to us instead of adjusting the machine yourself.

20. “The water from the tank tastes odd”

This is almost always a maintenance issue, not a defect: the reservoir should be refilled fresh daily.

1. Change the water in the reservoir daily (factory guidance).
2. Clean the reservoir weekly.

Source: La Marzocco — Linea Micra Manual

Stop line: If the taste stays odd despite a daily water change and a clean reservoir, it could be the local water quality or the machine — better to get in touch with us than keep guessing.

21. “How do I maintain or descale the Micra's steam boiler?”

Via regular draining rather than a descaling agent — La Marzocco doesn't provide a DIY descaling program for the home machines.

1. Every 1–2 months: switch off the machine, open the hot water outlet to drain it.
2. Refill the reservoir fresh afterward and restart the machine.
3. Keep within the water specification: hardness 70–100 ppm, pH 6.5–8.5, chloride ≤30 mg/l, chlorine 0–0.1 ppm.

Source: La Marzocco — Tech Tips · La Marzocco — Linea Micra Manual

Stop line: Never put descaling agent into the boiler or group — that's not documented as manufacturer-compliant for this model. If you notice limescale symptoms (e.g. weak steam despite a clean wand), get in touch with us instead of descaling it yourself.

22. “The app won't connect anymore or asks for a firmware update”

Usually the app's normal pairing or update logic is enough — intervening on the machine itself is practically never necessary.

1. Do the initial pairing only through the app; after that it reconnects automatically.
2. Carry out the firmware update as prompted in the app.
3. A green line in the app indicates the local connection is fine.

Stop line: If an update gets stuck, don't keep trying things yourself (e.g. reflashing repeatedly) — write to support@lamarzocco.com or to us.

Victoria Arduino E1 Prima / EXP / Pro

The E1 Prima family comes in three tiers: E1 Prima (operated via physical buttons), E1 Prima EXP (same base, additionally Pure Brew capable), and E1 Prima Pro (touchscreen, T3 Genius, VIS scale, Pure Brew conical filter, steam-by-wire). All three run on the NEO Engine, a multi-boiler system that doesn't keep large amounts of water hot permanently, but heats only what you actually need. The following steps apply to all three models unless we explicitly note an exception.

23. “The boiler doesn't fill, the display flashes”

This is usually a signal, not a direct defect — most often a simple restart of the auto-fill function helps.

1. Switch the machine off and on again so the auto-fill function restarts.
2. Check the water supply or tank — is there enough water and is the supply open?
3. Watch for any visible leaks around the machine.

Source: Victoria Arduino / Simonelli Group USA — E1 Prima Error Codes

Stop line: The water shut-off valve, pump, or level probe are pure service work — don't disassemble these yourself, contact us or the technician.

24. “The machine doesn't reach its target temperature”

The NEO Engine heats specifically only the amount of water you actually need; on the Pro, T3 Genius additionally regulates the steam boiler, coffee boiler, and group independently of each other. A persistent failure to reach the target temperature isn't normal behavior for any of the models — it's a signal.

1. Switch the machine off and on again, let it fully restart.
2. Check the power supply and the fuse.

Source: Victoria Arduino / Simonelli Group USA — E1 Prima Manual & Error Codes · Victoria Arduino — NEO Engine technology

Stop line: The thermal cutoff, heating element, or temperature sensor are exclusively a job for a technician — don't measure or open these yourself.

25. “Bluetooth or the app won't connect”

Usually a simple restart or a parameter reset in the app is enough — the machine only allows one active app connection at a time anyway.

1. Switch the machine off and on again.
2. Check whether another device is already connected — only one connection can exist at a time.
3. Reset the parameters in the app menu.

Source: Victoria Arduino / Simonelli Group USA — E1 Prima Manual · Victoria Arduino — “App” video (official channel)

Stop line: A firmware or board swap is technician work — don't attempt it yourself.

26. “The coffee tastes old or musty, the group looks dirty”

This is a maintenance issue, not a defect — Victoria Arduino recommends a fixed cleaning routine for the group, portafilter, and shower screen.

1. Daily: run the automatic cleaning cycle with the blind filter and a coffee machine powder cleaner.
2. Weekly: disassemble and clean the portafilter and filter basket.
3. Weekly: soak the shower screen and diffuser for roughly 30 minutes.

Source: Victoria Arduino / Simonelli Group USA — E1 Prima Manual · Victoria Arduino — “How to clean your E1 Prima” video (official channel)

Stop line: An important difference from our other machines in the lineup: you should NOT replace the shower screen and group gasket yourself on the Victoria Arduino once a year — the manufacturer explicitly names this as a task for a qualified specialist. Please turn to us or the service team for this.

27. “The Pure Brew filter clogs or is hard to clean”

Pure Brew is the low-pressure brewing method on the E1 Prima EXP and Pro: pulsed water delivery through a patented conical filter, selectable across three profiles (Light/Medium/Dark). The manufacturer names a brew time of under 3 minutes as a guideline — as with any extraction, though, taste decides; the time is only a reference point. The filter itself (20 g capacity per the manual; we also carry a 30 g variant) needs a quick bit of care after every use.

1. Empty the conical filter after every use.
2. Pry it out carefully from above — never press it against the work surface.
3. Clean it regularly; the filter is dishwasher-safe.

Source: Victoria Arduino / Simonelli Group USA — E1 Prima Pro Manual · Victoria Arduino — Pure Brew · Victoria Arduino — “PureBrew Coffee with E1 Prima EXP” video (official channel)

Stop line: The manufacturer doesn't name a fixed replacement interval for the conical filter — if you see visible wear, or Pure Brew changes noticeably despite a clean filter, talk to us instead of guessing.

28. “The machine is scaled up — how do I descale it?”

Not on your own with descaler at all: Victoria Arduino doesn't prescribe acid descaling by users for the E1 Prima family, but relies instead on water treatment that prevents scaling in the first place.

1. A water softener is mandatory, not an accessory — it prevents scaling instead of treating it afterward.
2. Keep within the water values: total hardness 50–60 ppm, TDS 50–250 ppm, pH 6.0–8.0, chlorine under 0.5 mg/l.
3. Regularly regenerate the softener's ion resin with cooking salt.

Source: Victoria Arduino / Simonelli Group USA — E1 Prima & E1 Prima Pro Manual

Stop line: Never put descaling agent into the boiler or group — the manual doesn't provide for this. Deviating from the water values also voids the warranty according to the manual. With scaling symptoms: service, not a DIY attempt.

29. “The app shows a maintenance or battery warning”

The maintenance counter is a reminder, not an automatic service — it's only meant to be reset after maintenance has actually been carried out.

1. Carry out the due maintenance (cleaning/inspection) as described in the manual.
2. Only reset the counter afterward in the app menu — resetting without carrying out the maintenance just hides the reminder.

Source: Victoria Arduino / Simonelli Group USA — E1 Prima Manual

Stop line: The internal CR1220 backup battery isn't described in the manual as a replacement step for end customers. Don't open it yourself for a battery warning — get in touch with us or the service team.

Profitec Pro 800

30. “Does the Pro 800 need power? I thought lever machines didn't need any”

Yes — the Pro 800 is a so-called dipper system: an electric, PID-controlled copper boiler (1600 W, approx. 3.5 l) assists the lever during brewing. On purely mechanical lever machines like the Flair or Superkop, by contrast, all the force comes purely from your arm and a gas spring, with no power and no boiler at all.

1. The copper boiler preheats electrically and under PID control.
2. The boiler pressure (approx. 1.0–1.25 bar, water supply approx. 2–3 bar) is steam/hot-water pressure — not the brew pressure.
3. Press the lever down: the boiler pressure lets hot water into the group for pre-infusion.
4. Lift the lever slightly and release it gently: it returns slowly to the neutral position on its own as the espresso runs through.

Source: Profitec, Pro 800 user manual (item no. 10810)

Stop line: The user manual mandates an initial walkthrough by the specialist retailer. Have the handling shown to you once at pickup or delivery before you start on your own.

31. “My Pro 800 doesn't pull any crema”

Usually it's down to the grind size, older coffee, or too little coffee in the basket — not the machine.

1. Set the grind size progressively finer and tamp firmer.
2. Use freshly ground coffee instead of coffee stored for longer.
3. Adjust the coffee amount to 7–9 g per cup.
4. Check the shower screen for buildup and clean it if needed.

Source: Profitec, Pro 800 user manual (item no. 10810)

Stop line: If this doesn't help: contact your Profitec specialist retailer instead of continuing to tinker with the machine yourself.

32. “The espresso barely runs through or not at all”

This usually points to too fine a grind size or too much coffee in the basket.

1. Set the grind size progressively coarser.
2. Tamp a bit less firmly.
3. Reduce the coffee amount to 7–9 g per cup if there was too much in the basket.

Source: Profitec, Pro 800 user manual (item no. 10810)

Stop line: If this doesn't help: contact your Profitec specialist retailer instead of continuing to tinker with the machine yourself.

33. “The Pro 800 won't switch on”

Usually it's the water tank or the switch, not a technical defect.

1. Check the tank fill level.
2. Check whether the float in the tank is stuck.
3. Check the tank/plumbed-in switch position.
4. Check that the tank is seated correctly.

Source: Profitec, Pro 800 user manual (item no. 10810)

Stop line: If it still won't start: don't keep disassembling it yourself — contact your Profitec specialist retailer.

34. “The portafilter drips after the shot”

Locking it in more firmly often helps — if it stays the same, the group gasket is likely worn.

1. Lock the portafilter in more firmly on the next shot.
2. If it stays the same: have the group gasket and shower screen replaced by the specialist retailer.

Source: Profitec, Pro 800 user manual (item no. 10810)

Stop line: Never remove the portafilter while residual pressure remains in the piston — that's a mandatory safety point per the user manual. For the gasket replacement and whenever unsure: contact your Profitec specialist retailer, don't disassemble it yourself.

Rocket Espresso — Cooling Flush & Cronometro

35. “The first coffee on my Giotto or Mozzafiato is too hot or tastes burnt”

This is normal on heat exchanger (HX) machines when the boiler has already been up to temperature for a while — a short cooling flush before the shot fixes it. On dual boiler machines like the R58 or R Cinquantotto, this isn't necessary, since the brew and service boilers are separate and PID-controlled.

1. Wait out the full heat-up time (roughly 20 minutes on E61 groups/heat exchanger machines).
2. Briefly run water through the group before the shot (cooling flush) to lower the temperature.
3. On the Appartamento, also check the TCA setting — exactly how this function works isn't fully documented for us either.
4. If the coffee stays consistently too hot: contact your specialist retailer/service instead of continuing to adjust it yourself.

Source: Coffee Coaching Club — our own technical/workshop experience with E61/heat exchanger machines (general espresso-technique practice; Rocket Espresso does not publish its own guide on this).

Stop line: Never open the boiler or heat exchanger yourself, don't adjust the pressure switch yourself. If the temperature stays consistently wrong: contact service/your specialist retailer.

36. “What does the Cronometro display on my Giotto or Mozzafiato actually show?”

Rocket doesn't explain this publicly in detail. Use the display only as a rough reference point, never as a target — taste, and weight/ratio in the cup, decide, not the clock.

1. Use the display at most as a consistency reference between two shots (runs similar to last time, yes/no).
2. Never dose or stop based on a fixed number of seconds — taste and the scale (weight/ratio) call the shot.
3. For context: in the current official Rocket catalog, the function is now called only “Shot Timer”, no longer “Cronometro” — whether it displays time or volume exactly isn't fully clear to us either.

Source: name “Shot Timer” from the official Rocket Espresso Domestic catalog (PDF). Context/handling recommendation: Coffee Coaching Club, our own experience — an official function description from Rocket Espresso doesn't exist publicly.

Stop line: Never rely on the Cronometro/timer display alone for dosing. If the coffee doesn't taste right: readjust grind size and dose based on taste and the scale, not the clock.

Bezzera

Bezzera publishes practically no public operating or troubleshooting documentation (only sales leaflets and spare-parts catalogs are freely accessible; the actual manuals sit behind a dealer login). The following steps are proven, manufacturer-consistent generic E61/dual boiler know-how from our own workshop experience — not a Bezzera guide.

37. “The group keeps dripping constantly, even after the shot”

1. Context: occasional drops while heating up are normal by design (the expansion valve briefly releases pressure).
2. Where available (3-way valve/DE models): blind basket backflush with cleaner.
3. Check the shower screen and group gasket for coffee residue or hardening.
4. If it stays constant or heavy: contact service instead of continuing to tinker with it yourself.

Source: Coffee Coaching Club — our own technical/workshop experience with E61 groups (Bezzera does not publish its own guide on this).

Stop line: Never open or adjust the expansion/overpressure valve yourself.

38. “No or little steam, the steam wand spits water”

1. Unscrew the tip (where designed for it) and clear the openings.
2. Purge it briefly after every use and wipe the wand while damp.
3. Check the water hardness, and if possible refill with softened or filtered water.
4. Watch the boiler pressure on the gauge.
5. No improvement: contact service.

Source: Coffee Coaching Club — our own technical/workshop experience (Bezzera does not publish its own guide on this).

Stop line: Never open the steam valve or boiler yourself; never push descaling solution through the steam path without a confirmed procedure.

39. “Machine stays cold or won't heat up anymore”

1. Test the outlet or fuse with another device.
2. Check the water tank's seating and fill level.
3. Let it cool unplugged for 30 minutes, then try a restart.
4. No improvement: contact service — the most common cause is a triggered over-temperature protection after dry running or limescale.

Source: Coffee Coaching Club — our own technical/workshop experience (Bezzera does not publish its own guide on this).

Stop line: Leave the housing, electrics, heating element, and thermostat exclusively to the workshop.

40. “The pump rattles loudly, or the gauge fluctuates during the shot”

1. Check and clean the tank fill level and the intake strainer.
2. Bleed briefly through the group without the portafilter.
3. Check the water hardness as a possible cause (see problem 38).
4. If the pump stays “dry and loud” with no water flow: switch it off immediately and contact service.

Source: Coffee Coaching Club — our own technical/workshop experience (Bezzera does not publish its own guide on this).

Stop line: Do not adjust the OPV or pump pressure yourself, do not remove the pump.

41. “Water runs out sideways from the portafilter”

1. Brush the gasket rim and shower screen.
2. Lock the portafilter in firmly, but without force.
3. Still leaking: replace the group gasket and shower screen as a set — a normal wear part, typical lifespan 6 to 12 months.
4. Fit it dry, tighten hand-tight.

Source: Coffee Coaching Club — our own technical/workshop experience (Bezzera does not publish its own guide on this).

Stop line: Don't force loose the group screws.

42. “On DE/PID models, the programmed volume is no longer correct”

Applies to volumetrically dosing models. After a grind-size or dose change, the old programming stays in place — usually not a defect, just a needed reprogramming.

1. Check the volume by weight (put the cup on the scale, don't judge it by time).
2. If it deviates, reprogram the dose button(s) on the control panel — the exact button sequence differs by model and isn't publicly documented; when in doubt check the control-panel menu or ask your Bezzera dealer.
3. If the volume keeps changing on its own: that points to the flow meter or limescale — contact service.

Source: Coffee Coaching Club — our own technical/workshop experience; the exact programming sequence isn't publicly available (only in the restricted Bezzera manual).

Stop line: Don't open the board or the flow meter yourself.
