Troubleshoot

The indicator light illuminates but water is not heated or the
water temperature is too low:
STEP ONE:
The water flow rate is too high. Reduce the water flow using the faucet. With
experimentation, an increase in water temperature should be observed. BE
CAREFUL, THE WATER EXITING THE FAUCET IS HOT. SCALD INJURY CAN
OCCUR FROM THE HOT WATER.
STEP TWO:
Make sure the unit is connected to the voltage supply specified on the U.L. rating
label located on the front cover of the unit.
STEP THREE:
Proceed to page 4 and follow STEP THREE.
Other possible solutions:
STEP ONE:
Note: Be sure electricity is turned “OFF” before proceeding.
Make sure the printed circuit board is mounted in the correct position. This is the top
set of mounting holes (See diagram below). Failure to mount the PCB in the correct
position will cause element burn out and may cause further damage to the unit.
(This board may have been incorrectly positioned if serviced previously).
