First, check for 24-volt power on terminals #20 and #21. If the power is present, you should replace the Detergent Controller P.C. Board. If there's no 24-volt power at #20 and #21, check for high voltage at the machine power source. If high voltage power is available, inspect the wiring to the transformer and from the transformer to the P.C. Board, repairing or replacing as necessary. If there's no high voltage power, check the power source or try an alternate one.
