burghere66 Posted February 4 Share Posted February 4 I installed a new Dometic Series 300 (321) toilet in our Monaco Windsor. It has worked flawlessly for the last 5 years. This morning after flusing several times the waste ball that rotates, when I step on the pedal, failed to open. Several attempts later and it still would not open when I step on the pedal. I was able to manually open it using my fingers, it rotates freely but doesn't close or move when the pedal is depressed or allowed to return to the upright position. The pedal seems to be detached from the ball. The pedal does spring back into place when you let up. I have checked out numerous Youtube videos on the Dometic 300 but none of them address this failure. Does anyone know how to diagnose and fix this problem?
