Group cover with flowmeter housing – one part instead of two problem areas
The group cover closes off the brew group at the top and carries the water from the valve into the group head. This version, part number SA944, comes with the housing for the flowmeter included. That is handy when the sealing surfaces at both points are worn.
Important distinction: the flowmeter itself is not included. What you receive is the housing it sits in. The measuring unit is a sensor and a separate part.
When it is due
It leaks at the transition to the group head, and new gaskets only last a short time. The sealing surfaces are eaten away by limescale or have scoring. A thread is stripped or was once tightened too far. Or the flowmeter housing shows cracks and fine traces of limescale at the threaded fittings.

Who it is for
For service technicians carrying out a thorough overhaul of a GB5 or Linea PB, and for businesses that want to fix a leaking group for good instead of retightening it every week.
Important for installation
The cover sits in the pressurised brew water line. The machine must be disconnected from the power supply, depressurised and cooled down before the group is opened. Whether the existing flowmeter can be transferred to the new housing is decided at the machine – for that reason, and because of the torque on the threaded fittings, this replacement belongs in the hands of a qualified technician. We deliberately do not provide step-by-step instructions here.
What goes with it
From our workshop in Bern and Zurich: When we have a group open, we lay the old gaskets side by side on the workbench and check whether they are compressed evenly – our own routine, not a manufacturer requirement. Uneven impressions reveal a sealing surface that is out of true before the next gasket fails on it. For the cup afterwards: Nutty Delight, Cozy Chocolate or Very Nutty from our coffee beans.
Returns excluded
Original spare parts are excluded from exchange and return. They are procured specifically for each order and cannot be resold after installation or a trial fitting on the machine. So before ordering, please check the model, year of manufacture and serial number of your machine – or drop us a quick message and we will confirm the fit together. Your rights in the event of defective goods remain unaffected.
Frequently asked questions
Is the flowmeter included?
No. You receive the group cover including the flowmeter housing, but without the measuring unit itself.
Are gaskets included?
No. We stock gaskets and O-rings separately, for example the O-ring for the flowmeter.
Does SA944 fit my machine?
The number is intended for GB5 and Linea PB. Because there are variants, we are happy to confirm the fit based on your serial number.
Can I install it myself?
We recommend a qualified technician. The part sits in the pressurised brew water line, and the installation determines whether it seals tightly.
Can I see the part in your showroom?
Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes. Drop us a quick line at [email protected] before your visit, and we will check whether the product you have in mind is currently there.
