i have a Franke Zurich kitchen tap and need to replace the ceramic disc valves. The instructions are straightforward: water off (at service valve - done); remove the H or C screw cover (done); remove the screw [.. and slide off the handle.] - PROBLEM.
Not the usual problem of the handle being stuck - I cannot undo the screw. It has both crosspoint and straight slots (see photo) and I have used both types of (manual) screwdriver but cannot get enough torque to loosen it.
I have tried the following without success:-
Turning clockwise to break the seal;
Tapping the head of the screwdriver (gently) to break the seal;
Squirting some white vinegar around the screwhead;
Squirting WD40 around the screwhead.
Any suggestions about what I should try next?
The tap is only two years old and Franke promptly sent me replacement valves (5-year guarantee.) I expected to replace the valves easily, as I have done previously on a much older Franke tap.
