Replace/overhaul support valve

Giriş

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.
