The cover that keeps the flowmeter sealed
The flowmeter counts how much water runs through the group – and that ultimately determines the amount in the cup. This cover closes the housing of the older, non-integrated design. It absorbs the pressure, holds the gasket in place and can be removed for cleaning without having to replace the whole unit.
A cover becomes an issue wherever things are opened often. If you have taken the flowmeter apart several times for descaling, you know the consequences: the seal groove is marked, the contact surface scratched, and at some point a fine wet trace remains on the housing even though the gasket is new. Then it is not the gasket that is to blame, but its counterpart.
Descale first, then replace
Flowmeters almost always cause trouble because of limescale, not because of a broken part. Before you replace parts, a thorough descaling and cleaning is worthwhile; the products for this are listed under Machine and grinder cleaning. If the cover still leaks afterwards or the contact surface is damaged, it is time for a replacement.
When it is due
Water leaks from the flowmeter housing even though the gasket is new. The contact surface is scratched or worn. The cover is cracked or a thread has given way. After several descaling cycles it no longer sits properly. Or you are opening the flowmeter anyway and replace the cover and gasket together.

Important for installation
The cover closes a pressurised point inside the machine. We do not provide step-by-step instructions for this: the machine must be depressurised and cooled down, the sealing surface clean, and the tightening torque determines whether it seals. This work belongs in experienced hands.
Who it is for
For service technicians who look after older La Marzocco machines, and for businesses where a wet spot remains on the flowmeter after descaling.
What goes with it
Matching parts are the O-ring for the flowmeter and, for the newer design, the flowmeter cover for GB5 and Linea PB. More parts are listed under La Marzocco accessories and spare parts and in the category Service parts.
Our routine from Bern and Zurich, not a manufacturer specification: we never descale flowmeters with the big brush; instead we place the parts in the solution and then rinse them thoroughly with clean water. Every scratch on the sealing surface is a future leak – and polishing a sealing surface takes longer than replacing the cover. Afterwards we check two shots with the scale and drink the third, usually Nutty Delight or Cozy Chocolate, and in a cappuccino the Very Nutty. More under Coffee beans.
Returns excluded
Service parts are excluded from exchange and return. They are procured to order and cannot be resold after installation or a trial fitting on the machine. Therefore, check the model, year of manufacture and serial number of your machine before ordering – or drop us a line and we will clarify the fit together. Your rights in the event of defective goods remain unaffected.
Frequently asked questions
Is the complete flowmeter included?
No. Only the cover is supplied. The flowmeter itself with its measuring part is a separate component.
What does non-integrated mean?
That is what La Marzocco calls the older design, in which the flowmeter is not integrated in the group cover. We check whether your machine has this version using the serial number.
Is a gasket included?
No, the gasket is a separate item. We recommend ordering it at the same time, because the cover is rarely the only cause.
Why is the shot volume inaccurate even though the cover is new?
Because the cover only seals and does not measure. If the volume remains irregular, the measuring part of the flowmeter needs to be checked.
Can I pick up the part at your showroom?
Yes. Bern, Gerberngasse 44 or Zurich, Hagenholzstrasse 50b. A short message is all it takes.
