This is an instructional guide detailing the E5 Error Code.
The E5 Error indicates a condition where the High Limit Temperature Sensor has sensed a high temperature (Greater than 248 F. / 120 C.) within the PCU Heater.
E5 will disable all functions and requires the PCU to be returned for service.
Due to the sensitive nature of the sensors and control electronics it is possible that the error code was triggered by a surge in the supply power, a momentary loss of supply power or even the effect of lightning.
Anytime an error code appears first perform the PCU RESET by plugging in the GFCI then press the TEST BUTTON on the GFCI - wait 5 seconds -then press the RESET BUTTON.
This will reset the Control Pack, if the error code returns then you will need to follow the corrective steps for that code.
If the E5 error code persists, please contact Customer Service as this is not user correctable.
