Water Pump Out

[MVP]

Hello everyone, we have a new Fleetwood Coach,

We're out on the road and our water pump stopped working. I checked the fuse, wiring harness and did the jiggle test. No luck.

Any tips???

Thanks in advance!

Check to see if you have 12+ DC volts to the pump. If not, trouble shoot back the circuit until you find voltage. If you do have voltage, time for a new pump. You mentioned "new RV", perhaps a warranty issue? All the best.

Definitely a warranty issue, just looking for help since we're out on the road, I'll break out my voltage tester in the morning. Thanks!

I'm sure you have more than one switch to turn the pump on have you tried a second switch? My water problem sounds similar to yours the following was what I needed to replace

latching relay

When our pump went out and after confirming that there was power to the pump, it only took a sharp tap on the pump to get it going again until we could replace it.

That is good to hear good luck happy travels

The pump should have +12v to it at all times and the controller that Vatlander showed switches the low (ground) side in response to the wall switches inside the coach.

If the ground is good at the pump and you don't have 12 volts at the pump pick up a length of number 16 wire at an auto parts or hardware store connect one end to the pump and the other end to the battery .this will allow the pump to run and cycle on the pressure switch. When you get home get it fixed under warranty

If you do what Roy1 suggest by hot wiring the pump, put an inline fuse in the circuit. a 7.5 or 10 amp fuse should be about the right size.

If as Gary RVRoamer says, then attaching a good ground at the pump should work and you won't need a fuse since the positive 12 volt supply to the pump is fused.

If it is the pressure activated switch in the pump, nothing to do until you can get a repair kit or replace the pump.

"MVP".....If your coach has multiple water pump switches throughout the coach, like one in the kitchen, bath, water bay, etc, that are momentary switches (meaning they spring back when pushed}, you mostly likely have a water pump latching relay. It's the device shown in the photo by "Vaflatlander".

Most new coaches use the latching relay. Here is how it works. They wire power to your water pump, so it has 12+ volts all the time. It does have a fuse. The negative side of the water pump runs to the latching relay. It's usually mounted on a wall within a few inches from the water pump. Every time you push one of the water pump switches, it makes a ground connection and sends a signal to the latching relay. It tells the latching relay to connect the ground to the water pump. Pushing the water pump switch again, disconnects the ground.

If you have a latching relay, you can test it by simply connecting a ground to the water pump. If the water pump turns on, you have a bad latching relay. They do go bad occasionally. In an emergency, just leave the ground connected while camping. The pump will shut off when the faucets are closed.

The latching relays are made by a couple of different companies, but are all the same. I like the Intellitec model sold on Amazon. I keep a spare.

Thanks to all for the help. It was the pressure switch. Fixed now. Had a 24/7 RV repairman come out. Thanks again to all!!!!

I guess some latching relays are wired differently. Mine was on the hot side of t.he circuit and when it went bad it took some time to locate it hidden in a wire bundle behind a cabinet.
