waterpump

Air lock? always unclip from inlet,then put pump into full water container and then put inlet connector into housing,that way air is released 

Hi penquinpete, If you have the handbook it should give you instructions on how to prime the water pump (green light I presume is under the bench seat?)  We had similar issues once when the pump wouldn't stop running and priming the system again worked  and once when scalding hot water was spluttering out of the shower, if you haven't got a handbook I can dig mine out when I get home tonight. Its just a case of pressing the flashing light,  and running taps in some sequence or other.

The other alternative might be the pressure switch. This is a small ,usually white, knob on top of a valve near the water inlet, in the front locker. If priming does not work then try turning this slowly to adjust the pressure and see if this helps.

If that does not work then borrowing a pump from another caravan might check if it is the pump that is simply broken.
