Dometic Flush Panel

I have a 2020 Dutch Star with Dometic macerator toilet with the hand-wave flush panel. About 15 months into ownership the flush panel became problematic. I called Diane at Dometic, the Dometic toilet guru. I explained the problem and that I had switched flush panel position mid to back. She wanted me to remove the toilet and check the controller. I told her once again what I had done and that I felt it was a faulty flush panel and after additional logic she agreed it was probably the flush panel. I asked since the coach was fairly new if it were covered under warranty. The answer was no, there was a one year warranty, no exceptions, no company good will, just fork over $250+ for a new flush panel. New flush panel installed, worked correctly for about 5 months. Another call to Diane, went through the same explanation a few times with the same responses from my previous conversation with her. Asked about warranty or company good will. No, warranty on replacement parts is only 3 months (why do replacement parts have a different warranty than new parts? Are they inferior to new parts?), no exceptions, go spend another $250+. My opinion, Dometic is selling junk, does not stand behind their product, and Newmar should look elsewhere for a better product.

I had the same issue with both of my hand wave switches at different times fail while under warranty. When I called Newmar, they were on back order on the switch panel with the hand wave function but had another switch that would work-it just has a fill and flush button but no hand wave function and the switches are real switches. We like the more basic switch much better and have not had a problem since replacing. When the second one failed, I specifically asked the Newmar parts guy for the same basic switch and he said no problem. Newmar/Dometic covered the costs for both but I was under warranty. Having two toilets, it makes it easy to swap switches to see if you are having a switch or controller issue.

Change to the push button panel and dump the hand wave panel.

Anyone happen to have the part number for the non wave switch?? I had to replace one of mine as well and couldn't get it from Newmar at the time, and they didn't offer any replacements at the time. Happened to find 2 of the wave versions at a marine supplier. I would like a mechanical backup on hand.
