I've got a Grohe Eau2 dual flush cistern and the discharge valve sometimes stays in the raised position after a full flush. (It is 6 years old so just out of warranty.) Part number for a full unit seems to be Discharge Valve, dual flush AV1 42 314 000
The leaflet that came with it has a lot of explanation if there is a problem with the filler valve, but nothing on the discharge valve.
Can anyone help in terms of how to remove it for inspection and, as important, how to put it back (if not starightforward).
I'm assuming that, once I've got the complete assembly out I look for any build up of scale etc or distortion that might cause the float not always to drop.
Any further hints would also be much appreciated.
I'm obviously hoping that I can get away without buying a full replacement unit
Many thanks
