We have two Thetford TECMA toilets in our RV which is almost 3 years old now. Only once or twice that I can remember that the red "Full" light has stayed on after emptying tanks. One or two times flushing out the tanks has always resolved the problem. In fact, over the three years the toilet sensors have worked wit 99% accuracy while the Black tank monitor systems works about 5% of the time. Based on testing on our coach there is about 8-10 gallons of extra capacity in the black tank even after the sensors say it is full so don't worry about overriding the system a couple of times before dumping. Would not push it much more than that just in case your sensor locations are closer to the top of the tank.
