We have just come back from our first trip away in our Cheyenne 632 (2004) no problems except that the heating pump wont stop. We have disconnected it by pulling a wire off of it in case we are damaging it. Does anyone know what we've done wrong? Many thanks.

Most likely a leak somewhere.... Does not have to be a big one and could be just a loose connection.. Also if you have a screw on filter make sure that is OK..

I have had this problem and it's most likely a collapsed diaphragm in the dump valve which causes a small drip leak which drops the pressure enough to kick start the pump
