Symptom
Possible Solution
No power to the
unit.
Verify the unit is plugged into a 15 Amp circuit and the Power Switch is set to the “ON” position.
If the unit does not have any power:
Check if the GFCI circuit breaker is tripped:
A) Remove the non-stick cover to inspect the plate. If there are any punctures or burn
marks you will have to replace the seal plate.
B) If there is no visible damage to the seal plate, the GFCI can be reset. If the GFCI
cannot be reset it can be replaced.
C) You’ll know the GFCI is reset when the red power light on the right of the unit glows.
D) If the GFCI trips, the seal plate might have moisture inside. Allow 1-2 days to dry out
and then try resetting it again.
