Truma pump not working - Avondale Perle

I have an Avondale Perle caravan (1990?) and the Truma submersible pump is not working, have checked the pump with a battery and it works OK.

I thought that the microswitches on the tap may be faulty, I removed the fridge and find that there is no wiring to the micro switches, is it possible that there is another pressure switch located elsewhere, if so maybe I should replace this, but where would I find it?
