Unhappy Dometic 8700 Toilet - Flashing Green Light

Got the dreaded red light the other day on the rear toilet, and had to turn off the house batteries to reset. Toilet worked fine for several days. Today, the green "power on" light started flashing continuously, like when changing flush modes, but it won't stop. Toilet won't flush, won't fill. Tried cutting the house batts. again but no luck. Any ideas?

Flush switch is malfunctioning

Circuit board in control module is
malfunctioning

Try unplugging the cable from control module or flush switch panel and see if it will reset

I disconnected the cables as suggested as well, and had no luck. However, the issue resolved itself after driving down the road a while. We got to our next campsite and everything was functioning normally. My only guess is that once the sensor in the tank cleared (which in my experience sometimes requires bouncing down the road a bit) the circuitry must have reset properly. Lesson learned: Yellow light means DUMP NOW !!
