Pulled into RV park and all three took a shower. Pump worked fine. Later, noticed light was out for switch. No voltage to pump when switching switch. Fuse panel on lower foot of bed frame, all fuses good. Checked breakers. Ok.any other suggestions appreciated. Pump was replaced 2 years ago with better pump. No problem trouble shooting the old one

Do you have a multimeter or 12 volt test light that you can use? I would test if the pump is even getting power. My guess though is the switch went bad so you'll want to check there too.

Take your voltage meter (if you do not have go get one) and see if you are getting voltage at switch. If you are getting voltage at switch, there may be a in line fuse at the water pump location.Good Luck

Do you have pump switches @ multiple locations? All out? If just 1 is not working, it's likely that switch.

If just 1 is not working, it's likely that switch.Also if you have multiple locations (you didn't state your RV model/make), you will most likely have a latching controller. If you replaced your pump with one that pulls more current and didn't replace the latching controller with a heavier duty one, it could easily fail as well.

Yes, I have a multimeter. No power to pump. Have 3 switches in various locations. Fuse for pump is also for control panel where you check tank levels. Haven't checked switches yet. Will do. Tank levels indicators are also not working. 2015 Tuscany 42HQ

Here again! Turns out it wasn't the water pump control itself. It was a lousy crimp on connector on ground wire. Replaced all 4 connectors on wires to control
Old control is good. Now have spare I'll probably never need.

First. Light out means it's not the fuse at the pump.

Question about those switches. are they ON/OFF toggles or are their three position spring loaded return to center momentary switches that feed signals to a control board somewhere..... Yup.

On my RV there were two 3-way switches (SPDT) and if no electronics between battery and pump.. just Fuse----Switch======Switch----Pump

(The two wires between the switches if both switches select the same wire pump is on. they are called 3-way because they have 3 connectors on the switch)

But another system is Fuse----Control board---pump
And a whole bunch of switches to the control board.. I've not seen one. but read about it.
