I am trying to replace the cartridges on a Franke Davos tap.
On the cold side I removed the cap, undid the retaining screw and slid the handle off the splines without problem.
On the hot side I have removed the cap and screw but the handle will not budge. I have sprayed with penetrating oil and WD40 and left it. I have managed to insert a putty knife into the space between the handle and tried levering it but without success. It seems to have moved about 1mm in total.
I contacted Franke Technical Support but they have been unable to assist beyond 'lever it off with a knife' - which hasn't worked.
Any ideas please?
