NOTE:  BE SURE ELECTRICITY IS TURNED OFF BEFORE PROCEEDING

 

 

STEP ONE: 
 
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 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).

 

 

 
 
 
 
 
 
 
 
 
 
 

 
 

 

 
 
 
 
 
 
 

 
 
 

 
 
 

 

The correct mounting holes
for the PCB on an “ES,EFC,
EFT” model.

Board mounted in correct

Inlet filter

 

STEP TWO: 
 
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.
