Could be a fuse, but may have something restraining the blades on the inside of the pump. Did you try to turn the pump manually to free it up? There should be a rubber grommet on the end opposite the end where the dump hose is connected. Pull out the rubber grommet and you should find the shaft end, where you can either use a screwdriver or a small hand healed drill with the correct bit to turn the macerator and free it up.

Thank you I'll try it! I confirmed the 20 amp fuse is blown but still trying to figure out why.

If something jammed it up (e.g.: TP, Wet Wipes, lose screw, etc), that may have blown the fuse. Let's hope it blew the fuse versus burn out the pump.

If you have a stinky slinky, you can quickly disconnect the hose from the drain (versus the end that hooks up to the macerator) and simply dump the old fashioned way. If you do that, remember to wear gloves, it can get messy as the hose may be full of liquid. I have had to do that, and if you do this carefully, after disconnecting the hose, you may be able to dump it directly into the stinky slinky hose before connecting it. Just be sure the other end of the stinky slinky is already hooked to the drain.

Btw, the reason I mentioned the lose screw is that when I got my new Thor Challenger, they had left maybe ten or more screws in one or both of the tanks, which came out into the macerator hose when I went to dump. It clogged the macerator. They had to replace the macerator, but it was under warranty.

I don't know if your macerator pump is inside a grey plastic box, but if so, and if needed, you can remove the pump by simply taking off the top of the box that is screwed to the bottom with screws in the corners. The pump is self contained and should simply be able to be lifted out of the box. The wires to the switch are connected to the side of the pump. The switch should be able to be removed from the box by simply removing the nut on the outside of the switch that sticks through the box wall. The reason I mention this is that, if necessary, this should make it easier to work on clearing the pump in the event it is jammed. To do that, you would disconnect the hose from the pump and you can use something like a screwdriver or a long needle nosed pliers to remove any debris from the neck of the pump that may be stuck in the empellers.

Anyway, those are simply some comments that may help deal with this, not so present, issue.

Good luck!

One more point, remember to close the drains before disconnecting the hose....

Which brand and type of Macerator?

I have a Flo-Jet portable (At least I think that is the brand)

On the non-pump end of the motor is a shaft with a slot, You can take a flat blade screwdriver, a quarter, a flat hnk of metal and turn the pump shaft by turning that slotted shaft, Attempt to turn in the same direction as the pump (You can figure that out by looking at the outlet connection, pump turns TOWARD the outlet.. It should turn fairly easily.

On the portable there is a fuse in the switch handle, it's on the bottom under a rubber cap, 20 amp blade type.

Mounted systems.. I suspect the slot, Can not help with fuse.

Thanks again
