TROUBLESHOOTING
6 Flash Amber code:
1) If the 6 flash amber code is present, it is okay to leave it as is if the performance of the water
heater is to your satisfaction. If the performance is inadequate, move the Setpoint Knob and
then move it back to its initial position and the water heater will resume its normal operation.
7 Flash Red code:
1) Turn "OFF" power to the water heater.
2) Ensure the tank is filled with cold water.
3) Open the upper handhole cover and check to see if the high limit switch is tripped by following the instructions
in the High Limit (ECO) Testing section on page 13.
4) Inspect connections to the Upper Temperature sensor by following the instructions in the Upper Temperature
Sensor Testing section on page 17
5) Open the Lower handhole cover and follow the instructions on Power Switch Module (PSM)
Testing on page 16.
6) Repeat step 4, this time checking between terminals 1 and 3.
(NOTE) Even if the Power Switch Module is determined to be non-functioning, check the
elements for functionality. This should be done as a potential cause of a bad Power Switch
Module is a faulty element.
7) If everything appears to be functioning normally, apply power to the water heater and turn
the control to a setpoint that will allow the control to enter StartGuard™.
