is it possible to change the electric switch and speed control on a grundfos pump and if so how to do it
 
it is a grudfos tf110 and the three way switch will not turn the pump on the pump turns manually ok
 
Unlikely the speed selector has failed. Much more likely the windings have failed. You're looking at a new pump.

You might be lucky. A merchants may still have these on the shelves but it's more likely you're going to be fitting a smart pump.

More expensive initially but it'll save you money in the long run.
 
pump works if you put pressure on the switch ie push the white slotted switch with a screwdriver
