On the basis of the above, I'm assuming that the internal switch has
gone rather than there being any problem with the synchro motor.

The microswitch is a bog standard Vsingle digit, and half decent
electronics supplier will have 'em. How ever it may not have failed.
The motor might not be opening the valve enough to operate the
switch. Take off the cover and see how far the mechanisium operates.
IIRC you can see the lever and button for the microswitch easily. It
maybe gunge in the wet side of the valve or lack of lubrication that
is presenting to much resistance for the motor. Take the motor head
off, excercise the wet side valve acutator and clean/lubricate the
mechanisium.

It's a button actuated V3 microswitch they use but a butchered one, you
have to shorten the terminals on the standard item and solder leads onto
the stubs. The o/p will need to be a half decent solderer with a good
iron to avoid melting the plastic body in the process (if that turns out
to be the fault).
