            The support valve is attached with four Torx T10 screws. Unscrew them.

            The seals on the support valve must be closed tightly with each brewing process and are heavily loaded. Replace them. 
- 
            The support valve is closed with a cover with a bayonet lock. Using a flat screwdriver, turn the lid a few degrees counterclockwise and lift it out with a pair of pliers. 
- 
            Check whether the inner parts (sliding piece, valve stem, and spring) can move freely and close tightly. Replace them if necessary.
