Could be airlock If you are on external barrel feed then try 'Bouncing' the pump up and down in the barrel of water, no not joking this usually helps to dispurs air. Can't see it's microswitches as all taps gone. Another piont to look for: Under the seat where the inlet comes in you may find a water pressure switch ...white with knurled knob on top. Turn this clockwise to close it.. turn on a cold tap....gradually turn the pressure switch knob anti clockwise to open and listen for the clicking at that point stop turning the knob.... Turn tap of [if it flowed] If not do the bounce again not kidding it's in caravan club instructions clearing airlocks. I used to use submersable pumps in joint chamber maintenance on GPO and that's how we cleared airlocks.
