I have a 17 3011 DS and I lost power to the water pump. Fuses are good ,I ran a power jumper and the pump works but not on the normal smart panel switch . Any help will be appreciated.

I am guessing you checked the fuse. Just had to ask.
If you can pull the panel that has the water pump switch on it, measure voltage on both sides with switch on and off. Obviously, when its on you will have voltage on both sides of the switch.
If no voltage there, look at the wire that goes to the fuse panel and make sure its wire hasn't pulled off the panel.

You said “Fuses are good....” How many water pump fuses do you have?
Most pumps I’ve seen have one fuse in the red line to the pump within 18” of the pump.

I agree. Most water pumps I’ve seen, have the in-line fuse just inches away from the actual pump itself. Did you check it?

The switch panel is a touch pad, not the standard switch panel . There is no voltage before the fuse .

I checked the fuse panel to be sure it wasn’t double fused, there is a fuse right before the pump. The fuse was good , no voltage coming in. Switch panel is a touch pad. I tapped into a hot line and went to the fuse and it works but I want it right not rigged up.

Do you have a picture of the touchpad and who makes it?
The fact that you have a touchpad makes it tougher to diagnose. The touchpad itself will control a module that is either solid state or a relay. First step is to find out what you have.

Lippert OneControl by chance?
If so, the touchpad connects to a controller module through what is called a CAN bus. The controller module has fuses on it which you need to check. The controller may say tank monitor on it.
This is just a guess before you come back and say what you have but may get you headed in the right direction.

Follow the CAN bus 2 wire outlet from the back of the touchpad to the control module. It may be in a cabinet and will look like the one in this link. May not be exactly this module.
https://support.lci1.com/onecontrol-...s-tank-monitor
It will have a 30A circuit that feeds it but if that fuse was blown, other functions like tank level won't be working. Everything else is working right?

Mine is a 3051 and the LCI module is behind a panel below the main control pad. It’s in the wide panel shown at the bottom of this picture:
The pump control is here.
Put a voltmeter on output #3 and check for voltage as you turn the pump on and off. You should also hear a relay clicking.

The One Control tank monitor module is what controls the power to the water pump. On a 3011 it is located under the bedroom wardrobe drawers. You will need to remove the drawers to access the module. Expect to also find a rats nest of wires.
If the water heater electric and gas functions are working correctly it should just be a blown fuse on The module for the pump. As long as the water heater and pump icons show up on the touch screen the module is receiving power. The power is fed to the module from a fuse in the Battery Control Center located in the entry step area.

Thanks to all that helped out with info , Steve W provided the exact location of the modules . I found a blown fuse now it is all good. The system was double fused ( one at module and one at the pump ). Learned a lot thanks to all .

Great!
It's gratifying finding and fixing issues on your own and not having to return to the dealer!
And, thanks for coming back and reporting the fix.
Many who come here and ask a question never return once their issue is corrected.
Your information will help others experiencing a similar issue.
