I have a bay that the pre-soak function does not shut off. I have a Dixmor timer in the bay. I think I have eliminated that as a cause by plugging a different timer in and get the same result. The pre-soak indicator light stays on in the panel above the pump and the solenoids for the air and chemical for the pre-soak say open. No other function works on the bay. No wiring has been changed or disturbed. I was wondering if it is likely this GinSan controller or timer above the pump? The only way I have found to shut it off is the breaker for the bay.
