Check the water level pressure switch. Should be closed with tub empty and open when full. There may be gunk in the air dome and hose on the lower left side of the outer tub hindering operation of the pressure switch. If the pressure switch is operating properly, check continuity from power cord neutral (large blade) and the wht/red wires on the water valve solenoid plugs and continuity from water valve plugs to control board. If pressure switch and continuity checks are good, it’s likely a bad control board.
