Micro Minnie (1704RD) Water Pump Issue

[CatsAndCamp]

Hey fellow campers. Trying to diagnose why our water pump isn't working (hasn't worked since we pulled away from the dealer lot) and I'm unable to even find the pump.

I called winnebago service and they don't me it was behind the panel under the bed and I don't see the pump there. Does anyone know how to access the water pump or have any suggestions diagnosing this thing? I've got a full water tank, pump turned on, I suspect a valve is closed somewhere from winterizing that needs to be opened but I can't get to it.

See attached of where the winnebago service rep told me the pump was.

Peace!

In our 2106FBS the bottom of the cabinet under the sink it removable to get access to the pump. If it is similar there will be two valves near the pump. One is opened to use the water tank. It is closed to winterize and the other valve is opened to fill the system with antifreeze. Sounds like you might still be set up for winterizing.

Thanks old_engineer, I suspect you are right and we are stuck in winterizing mode.

I'm scratching my head because the winnebago tech told me the pump was under the bed, and the schematic shows the same. Attached what I see under the bed and theres no pump, or easy access to it. It appears those lines are under the furnace maybe? Not sure how to access that.

Edit: the forum keeps making my photo upside-down no matter how I rotate it when I submit it ¯\_(ツ)_/¯

Pumps are usually near the tank. Can you her the pump at all when you turn it on? They are loud even when no water is in them so you should be able to locate the pump by the noise. If it is under the furnace/converter cabinet you should be able to access it by removing the converter. Just be sure to have the battery disconnected when you do.



Looking at your picture I would expect to see the tank water line feeding the pump to come up through the same hole as the fill pipe. Does the hole go under the side wall of the cabinet? If yes do you see a water line? I've attached a copy of the 31 gal fresh water tank I was sent when ours was leaking. My guess is your trailer uses the same one. Hopefully it will help locate things.



One last thing is the trailer might have gone out without a pump being installed. It wouldn't be the first time an RV manufacturer employee did something as boneheaded as that.

Thanks everyone! Figured the issue out it was a blown fuse (the inline one by the pump itself)


Okay now to where the pump is... its not where the diagram says it is. Service said it was under the bed (its not) its actually inside the wardrobe cabinet at the bottom. To access it you have to take off the electrical panel. Woof that was an afternoon in 90 degree heat.

Glad you got it squared away, and thanks for reporting back. Your info might help someone else sometime.

Good to hear you've found the problem. It might be worth considering running the hidden fuse through the wall so it is on the side you can access from under the bed.

In our unit(1706fb), I had to remove drawer under bed and you will see pump on drivers side. Hope this helps

Phew! All this makes me glad my water pump is easily accessible in my coach basement.
