Make sure the PCB's (Printed Circuit Boards) are correctly mounted:
BE SURE ELECTRICTY 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).
Note: The upper mounting position is
applicable to all modules regardless
of their type.
Inspect the inlet filter
Inspect the inlet filter (See diagram above for location). Make sure the inlet filter screen is free
from debris, pipe dope or any other foreign materials that may prevent adequate water flow.
