Sliding dispenser cover not opening, already replaced the actuator spindle and now replaced the the wax actuator as well but it still fails to operate during a cleaning cycle. Manually tripping the actuator arm releases the dispenser cover without problem. I can only assume that the new wax actuator is functional (probably the old one too) so it would seem that whatever switches power to the wax actuator is not performing. Is there something I can look at to troubleshoot this further or is time to replace the washer? Cheers.
