The support valve connects to the brew group during every brewing process. It is either opened by the brew group itself, or the valve inside opens when a certain pressure (around 4 bar) is exceeded. The hot water can then flow into the brew group. The seals on the support valve are subject to considerable stress and should be replaced and lubricated regularly.

The instructions can also be found for other [ [Topic:Saeco Coffee Maker|Saeco|new_window=true]] models and other fully automatic coffee machines from Philips and Gaggia – the machines are all from the same manufacturer and are very similar in design."

Note: Some of the images are from a different model and may differ slightly. However, the repair process is basically the same.

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.

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.
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.
