Macerator issue

[Miamibill95]

2018 precept 31 ul macerator worked one trip. Next trip nothing. Love this thing.
Besides obvious fuse check, have u seen switch go bad ?
Is there something between switch and motor that protects motor that may have failed ?
I hate thought that motor has failed and I have to tear it apart to replace.
I searched past threads but could not find this answer.
Thank you for the help

Where was the fuse you checked? I have the wiring diagram for the mazerator but no fuses are shown. My 2018 35S is having the same issue.

I have not looked yet but was figuring that would be first place to look in panel under bed and go from there. Wanted to reach out to see if anyone had the same issue they resolved

I have a 2018 31UL and my macerator is intermittent. I'm thinking poor ground. nhake01, would love to have a copy of the wiring diagram if you could pm me.

Traced wires what I could. Have not found relay. Disconnecting Toad this morning and I hear a motor noise. What is that and where is it ?
Found it to be macerator running. Open water bay turn switch up and it stops.
What is going on with this thing ?

I think it's a bad ground or bad switch. Had the same thing happen to me, macerator didn't work, came home and was cleaning up and I heard it running. I probably left the switch in the on position, and the ride home jiggled the ground wire or switch till it made connection.

Will check it out To see if I duplicate the wiggle or jiggle. Of course I will Do that in the privacy of my garage.
