Saeco Xelsis/GranAroma Support valve replacement/overhaul

ID: 181091

Description: The support valve connects to the brew group...

Steps:

1. If the brewing unit is still in the machine, remove it now.
2. The support valve will become visible. It is attached with two Torx T10 screws. Unscrew them.
3. Pull the support valve out towards you, using a little force and wiggling movements.
4. Pay attention to the seals: there is a double seal at the inlet, which may also get stuck in the opening. Replace it.
5. There are two seals at the outlet, with the larger one at the top. Replace them.

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

8. The valve stem points upwards.
9. If the two green O-rings do no longer properly seal, the valve will no longer work. Replace the seals.
10. Picture 2 shows a valve where the opening was completely caked with limescale. The machine was able to produce water for tea, but of course no coffee. After some time soaking in descaler, the valve opening was cleared up again.
