Water pump shuts off all by it self

The most common cause of failure of a water pump latching relay is water corrosion. Most OEM's install the relay in the water bay area and anytime you get a leak from the water system or even just the humidity from the water bay will cause the relay to corrode and fail. Cleaning the contacs does not fix the relay. Instead of cleaning, take it apart and look at the circuit board. You will find tell tale corrosion and cleaning just temporarily makes it work. Doug

Actually, the controllers are great. You can add a 100 water pump switches if you want, by just running one wire. They're a great system and most last a lifetime.

Glad mine doesn't have a control module!

If you have multiple water pump switches that are "momentary" switches (you push them and they spring back), you have a latching device for your water pump. The latching device looks like this.......



They're typically located within 12"- 24" of the water pump and are all the same. They're available at Amazon for about $35.00. I carry a spare.

Same with me it was the control module. Opened it up cleaned the contacts put it back together and now it works fine.

What indicates that it is "off" ?
The switch in the wrong position.......or an indicator light OFF ??

Either way, it is probably a switch going bad or a wire loose on the back of the switch.

It still works fine but this is new. My coach is 7 years old. Maybe a ground wire or a switch , I have never herd of this problem but thought I would see if any body has had this problems and what they found out.

Something similar happened to mine once. It would toggle between Off/On and On/Off seemingly randomly. I never did figure out what caused it but it went away as soon as I pulled the wires off the control module (inside the wet bay very near the pump) and cleaned the contacts.

Can't help other than that because they are very reliable and don't go bad very often so not much expirience.

Has there been rain where you are? I'm wondering if you got a drop of water or two on the control contacts or on the contacts of one of the switches? Check the basement pump switch first, if you have one.

Sounds like there's a latching relay or "pump controller" involved that's developed a mind of its own.
