fuse for electric flush on c2 cassette toilet has blown , does this point to the pump shorting out or does it point to the switch mechanism

geoff, July 2008

I had the same problen ie: no flush. Removed the pump and cut the cable. I tested the pump and it worked fine but noticed one of the twin wires was blackened so instead of re-connecting decided to buy a new pump with new cable attached. Rejoining a cable which will be immersed is not for the novice as it has to have a waterproof sleeve heat moulded in place. After a few years most caravan copper cables will blacken and not conduct properly. I intend to replace both pump and switch anyway. Hope this helps towards a decision

Don't know but try replacing fuse and see what happens if it blows again it could be short on wiring pump or switch which is earthing.
