+5V status light is off:

+5V status light is on:

•Check toilet fuse or circuit breaker at DC distribution panel.

•Check for loose or defective wiring between control module and DC distribution panel.

•Check for reverse polarity of input power to control module.

•If all of above check OK, replace control module.

•Input power must be 10 volts or higher.

•Check control module for error codes.

•Put Mode Switch in SERVICE position. If flush valve opens, go to next step. If the flush valve does not open, go to Symptom 2.

•Put the Mode Switch in NORMAL position and push handle or switch to "Flush" while observing “FLUSH” status light. The “FLUSH” status light must come on when the switch is pushed and go off when the switch is released.

•Disconnect either the purple or yellow wire from the Open Limit Switch.

•With DC voltmeter test leads across pins 9 and 10, flip the Mode Switch between the NORMAL and SERVICE positions. If voltage is present for about two seconds in the SERVICE position, the flush valve motor or related wiring is defective. If voltage is not present, replace the control module.
