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.

hear another CLICK. That is the ozonator being turned on.
