2019 Scamp 16 water pump not working

Hi all,

Need your expertise here. I just noticed today that the 12v water pump is not working. When I flip the switch to the on position, nothing happens. I pulled out the switch and put a meter on. One wire is black/white and the other is white. I believe the black/white is where the 12v power is coming from. I put a meter on both wires and I'm not getting 12v (only very little mV). I tried the water pump by the shower and it's working. Is there a fuse for the 12v water pump? I checked all the 12v fuse and they are all good. Is there a separate fuse for the water pump? Where should I start to troubleshoot the problem?

Thanks so much!!

If Scamp is still using the Shurflo pump they do not have their own fuse at the pump. They do have a thermal cutout that will activate above a certain temperature but it resets when it cools down. Can you access the wiring and provide 12V directly to the pump? That will tell you quickly if the pump is the problem or if itís something related to the switch/wiring.

Rubicon, thank you for your reply. I finally got it to work...being a newbie to travel trailers and the whole RV thing, I made the newbie mistake.

I never try turning on the faucet before turning the pump. As soon as I turned on the switch and the pump didn't run, I thought it was not working. I tested the voltage on the switch and I got nothing. I then tested the voltage on the drain pump by the shower and I got 12v. So I thought there must be a line power issue somewhere.

I did more googling and one post on another site mentioned that the pump won't turn on where there is enough pressure in the line. So...I turned on the faucet and let some water out and then turn on the switch again and it kicked on...

I guess it was the water pump safety mechanism prevented the water line from over pressurizing. When the pump was running, I measured the voltage again and I still got nothing. I guess the wires on the switch are the negative wire which completes the return, therefore, no voltage reading.

This is a newbie mistake. Sorry for posting. I hope other newbie won't make the same mistake I made.

Glad you figured it out. The pump has a pressure switch. Cut-in (on) at 40PSI; cut-out (off) at 55psi. Also when you measured the voltage at the switch you will not have gotten a proper measurement if you were simply measuring across the switch. The switch is simply making and breaking the positive wire. You would have to get your negative probe on a good ground. Sometimes that means extending a wire over from a known ground if needed.
