1. Check wiring harness to the water flow servo for loose, broken or damaged connections from
servo back to PC board.
2. Turn off the power to the water heater and then reapply to see if code resets.
3. The water flow servo valve has failed to close during the bath fill function. Immediately turn off
the water flow and discontinue the bath fill function.
4. WARNING: Turn off the electrical, gas and water supply to the water heater before proceeding.
Replace water flow control servo.
If the water flow servo motor is disconnected when the unit tries to cycle the product will post a

turned off and then on again.
