HELP! TOILETS HAVE RED LIGHTS ON SOLID, THOUGH THEY FLUSH. BLACKWATER TANK WAS DRAINED THIS MORNING AND STEAM CLEANED. EVERYTHING WAS FINE. LEFT AND CAME BACK AND RED SOLID LIGHT IS ON. ANY HELP GREATLY APPRECIATED! I am at the dock...
Pending the Sensor type; Knocked it apart, deformed it or it's stuck with debris in the wrong position. Steam cleaning a black water tank, that's a new one to me.
The tank sensor actually doesn't control the panel light directly, but it triggers a relay, which could also be stuck, theoretically. But considering the coincidence with the steam cleaning, it's more likely that the sensor was damaged. Also because I think it's a pressure-based type, very unlikely to be designed to withstand hot steam...
