Macerator noise

Rig info
2011 Fleetwood 40K

I did the big no-no in macerator toilet useage, Without prior knowledge I used Charmin Ultra Strong TP. Now it is making noise like something is in there. I want to see if there is any way to dissolve any TP that might be stuck in the pump or will I need to pull the toilet. It is a Dometic Masterflush 8963. It is flushing fine just making a loud noise.

After recently working on my bath shades behind my Dometic toilet, my macerator began making a noise that sounded like something metal was in there. I had no choice but to “operate”…remove the toilet & all that goes with it. A YouTube video guided me through it, nicely. I found that I had brushed against a wall ornament, causing a piece of soft metal to fall onto the toilet behind the seat and enter the toilet under the closed seat. I was surprised to discover the size of the opening there, large enough to allow a “problem” for the macerator. Think that could be your problem, rather than your TP? Good luck!

I never hear my macerator, maybe it's because it is home in the storage building.

I agree with hugh37, if the sound is more than a highspeed impeller running in water, you better get whatever's in there out before the damage gets worse.

I found the issue. I removed the toilet and pump and found a non-flusable wipe in there. Removed this and everything is good now. Seems one fell in without our knowledge.
Thanks for the response.
