    Water pump inop...

    Ok, it was time to sanitize, and test plumbing system this week but got held up by a water pump that doesn't want to run.. I'm aware of the two 3-way toggles. Neither indicator lights for the pump are coming on. I checked the fuse panel but there doesn't appear to be a fuse for the pump on it. Is there an inline fuse someplace in the open or do I need to remove a panel in the storage area??

    TIA

    There should be a in-line fuse right at the pump.

    And the pump is located behind the valve control panel?

    Yes it is. You may as well leave the access panel off when you're checking the water system to check for leaks. It's also an opportunity to check the heating ducts from the furnace to make sure they're all OK. I had the 3" duct off the furnace connection when I checked mine.

    Will do Dave. I'll take a look tomorrow. I'm kind of disappointed with my dealer that they overlooked this. Thank you.

    Hi @Julie n Kevin,

    There is an in-line 10 amp fuse in the wiring coming off the switch behind the outside utility center. Remove the access panel in the front pass-through storage area and follow the wires from the switch.

    Best regards,

    Traced down water pump issue to the interior control panel. Power lead wire to the inside switch was disconnected. Simple fix. Crimp hot female end to fit spade better.

    Got a good look at the mechanical parts of the 303. The jury is still out.

    The pump in our 337 is putting out VERY LITTLE pressure or volume! We are dry-camping in our church parking lot with a Honda EU2000 generator. I pulled the panel in the belly, and the blue inlet hose to the pump was kinked almost shut. I rerouted it around the cables for the dump valves for a more open path, checked the inline filter- very clear. But no improvement. I am thinking the Flojet pump is defective, it runs but no pressure. I have triple checked the valve positions, all seem OK. The service advisor at our dealership said there is a pressure adjustment at the pump, but I can't decipher it! He said if we have to bring it in, they are scheduling for June! Not a very acceptable answer after we gave them a

    Have you checked the screen in the faucet aerator? Is the low pressure at the kitchen faucet or all faucets? I've noticed that the pressure is lower at the kitchen compared to the bathroom sink faucet or shower in our unit...longer distance from the pump I think.
