coachman laser 650/4

[tommyrodman]

hi
I have recently purchased a coachman laser caravan and I can't get water to work . I bought a new pump and new leisure battery and still nothing . I took the face off the truma surge damper/water pressure switch and looks like water has got past the small o ring damaging the PCB...the part is now obsolete and can't find anywhere that can repair it..I have a holiday coming up in 2 weeks and I really don't want to go without water ..has anyone had similar problems ? 1. would that damaged PCB result in water pump not working and 2. can it be repaired ..I have attached a few pics ...thanks in advance Tommy

You could try a caravan breakers for the part

The damage looks quite extensive, and I suspect the the tracks on the PCB will be compromised, so a repair is unlikely.

You will need to replace the Truma circuit with a pressure switch. and the most common one is the Whale e.g.
