Question

I have a 2006 Lunar Champ H621 motorhome and have just lost power to my water pump. All the fuses are ok but there is no power getting to the pump when I turn any of the 3 taps on. I now suspect the micro switches in all the taps have failed but I cannot work out how to get to them. They are all lift and quarter turn (hot one way, cold the other) taps, but don't know the make of any of them

Answer

It is unlikely that all microswitches have failed at the same time. Beneath the taps you will find the wires that connect to the microswitches. If you disconnect or cut these wires beneath one of the taps and join the two wires together then this will by pass the microswitch and the pump should run. If the pump fails to operate then you must look at the pump itself or check the wiring.
