The utility room sink in my mother's house has a Franke mixer tap on it. It's probably about 20 years old. Last time I looked I could see no model number. I think it might be this:
The lefthand control has become stiff, quite hard to turn; to me it feels as if there may be some grit in the mechanism, and perhaps if I strip it and clean it the problem will go away. The tap still turns on & off ok and isn't leaking.
But I have a disassembly problem. Referencing the parts shown in the diagram at that webpage, I prised out the coloured cap (2) and then undid the screw under it, on the lefthand control. I expected the lever part (3) then to come off easily, but I cannot move it. I tried gripping the lever part in my fist and pulling it to the left, and I also tried wiggling a fine blade screwdriver into the narrow gap between the rotating lever part and the main body of the tap.
I also took the cap & screw off the righthand side of the tap, and couldn't then free the lever part at that side either.
I was afraid to try what might be excessive force to remove the levers, not knowing if I might damage something.
I see from the list of parts that an allen key is mentioned; does anyone know what that is for?
