b. Otherwise, replace the pressure switch to gain dependability.  
 
IF shorting out the pressure switch does NOT solve the problem, the failure is the 
board itself. Double check that the pressure switch cord to make sure it’s plugged 
securely into the board and the cord isn’t cut. IF not, your short is telling the board 
water movement is happening and it’s ignoring the signal. This rarely happens but 
when it does, you have to replace the board. 
 
 
The CLICKS are not over: 
 
After the pump and heater come on and don’t touch any topside control, you will 
hear another CLICK. That is the ozonator being turned on.
