Water Pump switches not working

I've seen that happen a couple times over the years.

Pull the fuse out and if possible swap it with another one of equal amperage.

I just replaced mine in my Imperial. It was located behind my monitor panel for the tanks etc. The way I found mine was by working all the switches and found the clicking noise coming from behind that panel.

I ordered mine from Northwest RV. It was $44. My local rv dealer wanted $120

Not that I'm aware of dsisemore1. The fuse is within 6" of the pump, and in-line fuse holder with a plug in European style blade fuse. Sometimes they are taped up with electrical tape. They are often difficult to spot in the tangle of wire and flotsam inside the water compartment.

DSDP Don I live in Baton Rouge, LA. I have a mobile RV service coming this morning sounds like this should be an issue they can handle. Thanks again. One other question I think in the owners manual it mentions something about an inline fuse. I looked everywhere and cannot locate it. Does this controller replace that?

Controller on our previous motorhome failed. I made up a small cheater wire to bypass the controller. I kept it in the bay with the controller after installing a new one. Your pump has a built in pressure switch so it will only run when it needs to supply water so bypassing the controller is not a big deal.

Thank you so much DSDP Don sounds exactly right. I just hope I can locate a latching controller quickly. I don't know if camping world or any of the other local dealers would stock that item. I hope so we are trying to leave on a 6 week trip - day after tomorrow.

"dsisemore1".....Your water pump is controlled by a latching controller. Your water pump is connected to the controller along with the 12 volt power for the pump. All the switches in your coach are then connected to the controller. A controller is used to save on wiring and you can literally attach 100 switches to it and it doesn't care. If you've noticed, all of your switches are momentary. That means when you press one, it springs back. When you push one of your switches, it momentarily connects the wire going into the switch to ground. Every time the controller sees a switch connect to ground, it either turns on the pump or turns off the pump.

Here is what the controller looks like: Intellitec There are other brands, but they look alike. They're about the size of an open matchbook.

With all that said, the controller is USUALLY located near the water pump (within 12"-24", in the wet bay. You can test to see if you have 12 volt power to controller, if you do, the controller is probably bad. If you don't, you have a 12 volt power issue. On my last coach the controller lasted 10 years and as far as I know, it's still working. On my new coach, the controller failed after 9 months. It was an off brand, so I replaced it with an Intellitec model. It was a direct replacement.

Aren't most of those water pumps outfitted with a plug in fuse right near (6") the motor? I know mine is.

Also, depending on the part of the country I hang out in, every once in a while, I have to clean the connectors at the controller. Which is in the water compartment near the pump.
