Aqua Logic AQL PS-4 control panel will not turn on or off

Customer Question

Aqua Logic AQL PS-4 control panel will not turn on or off filter pump. It makes a clicking sound and must be in the lit (on) position to work, but I have to turn pump on and off by the breaker. The rest of the panel controls seem to work properly when pressed. Pump motor was recently replaced.

This means the contacts for pump relay are welded shut.
The only fix for this is to replace the board that pump wires attach to. The board thinks it turns them off, but the contacts are stuck in the closed position.
Even if you get them unstuck...they always stick again.
