Controller on wall flashes red triangle and water level blinks yellow to green alternately. Called Thetford customer service at:1-800-543-1219 Basically no help other than to send me a troubleshooting guide that talked a lot about voltage checking. I was confident it was not a voltage issue so I used a Youtube video to show me how to remove and take apart the toilet to check pump for blockage. There are plenty of videos, but I used this one: One difference on my toilet was there was a hard black PVC pipe coming out of the floor about 8" to the pump discharge hose. This meant I had to spin the toilet clockwise after removing the 4 bolts holding it to the floor. This allowed me to access the rear opening of the toilet to disconnect plumbing and wiring. Once plumbing and wiring was disconnected I was able to lift the toilet straight up to get it over that hard pipe. I removed the pump and bench tested it. It did not turn. I took the pump apart and there it was.... a SOCK stuck in the macerator area. This must have happened as my wife was emptying the drying, which is right above the toilet. Removed sock, bench test sat. One thing I didn't do was put caulk between toilet and floor. I don't think it is necessary. One note of caution: when putting the bolts back to secure the toilet to the floor, be careful of torq. This is porcelain and can crack with too much torq.
