The complete steam unit of the GB5 in one part
This valve assembly combines the steam control of the GB5 into one complete unit. Instead of individual parts, you get the pre-assembled unit, which noticeably shortens the replacement. It is due when the old valve leaks permanently or several parts are worn at the same time.
The complete valve assembly carries the number B.1.001.02.R. The part number is B.1.001.02.R.
When it is due
- The steam valve drips despite new seals.
- Several parts of the steam unit are worn at the same time.
- The valve assembly is damaged or corroded.
- A complete replacement is quicker than repairing individual parts.

Important for installation
The valve assembly sits on hot, steam-carrying lines. That is why we do not provide step-by-step instructions. The machine must be depressurised and cooled down, and the replacement belongs in the hands of a specialist.
Who it is for
For technicians who renew the entire steam unit of the GB5 in one go.
What goes with it
From our workshop in Bern and Zurich
We reach for the complete valve assembly when a single repair has already failed to last twice – in the end, that saves time at the counter. That is our routine, not a manufacturer's specification. Then we pull an espresso with Very Nutty and check that everything is right – more in our coffee beans.
Returns excluded
Spare parts are excluded from exchange and return. They are procured to order and cannot be resold after being installed or test-fitted on the machine. So before ordering, check the model, year of manufacture and serial number of your machine – or drop us a line and we will clarify the fit together. Your rights in the event of defective goods remain unaffected.
