We’re new to this website. Any help is appreciated.
Have a 2018 Mobile Suites with Thetford Tecma Silence Plus toilet that will not flush. Funny thing, after failing the first time it flushed two mornings in a row for about 3 flushes then quit for the day. Today nothing. It seems to fill ok and when it did flush it acted and sounded normal so nothing stuck in pump. Also noticed bubbles coming up into the bowl. Didn’t have that before but that seems like it could be a vent issue.

Might try the ThorOwners forum/DRV....many more recent models posting there. Tecma seems to have quirky problems, glad I have the old style.

We have a 2019 41 RKSB4 with the Tecma toilet. It wouldn't flush one day when new. That's when I learned not to let the holding tank fill too much. The led readout said tank was 68% full but the light on the Tecma flush control was red. Emptied the tank and all was fine. Perhaps a wiring problem in the sensor setup? I dump as soon as the light turns yellow (50%, according to Tecma), no biggie, no problems.
