Introduction
The support valve docks with the brewing group during each brewing process. Either the brewing group itself opens it, or the valve inside opens when a certain pressure (about 4 bar) is exceeded. Then the hot water can flow into the brewing group. The seals on the support valve are subject to quite a lot of wear and should be replaced and greased regularly.
The instructions can also help with Saeco models and with other fully automatic coffee machines from Philips and Gaggia – the devices are all from the same manufacturer and are very similar in design.
Tools
-
-
If the brewing unit is still in the machine, remove it now.
-
The support valve will become visible. It is attached with two Torx T10 screws. Unscrew them.
-
Pull the support valve out towards you, using a little force and wiggling movements.
-
Pay attention to the seals: there is a double seal at the inlet, which may also get stuck in the opening. Replace it.
-
There are two seals at the outlet, with the larger one at the top. Replace them.
-

Turn the valve so that the top is facing you. You will see a slot. Take a flat screwdriver and turn it slightly counterclockwise.
-
Use some tweezers to carefully lift out the inside of the valve
-

The valve stem points upwards.

If the two green O-rings do no longer properly seal, the valve will no longer work. Replace the seals.
