If water is detected in an idle state(no cycle running), then the dishwasher will indicateLeak Detected and will not start.A 5 VDC signal is sent to the moisture sensor. Ifenough water leaks into the pan it will short acrossthe sensor probes, returning 5 VDC back to thecontrol. This will alert the consumer of a leak.The fault may reset if no water is detected. Itis possible for the water to evaporate and thedishwasher would restart with no water detected.Only active faults are displayed on the control.If the consumer tries to restart the dishwasher withwater still detected, the dishwasher will not restart.A physical inspection should be completed todetermine the source of the leak, with repairsperformed as needed. The moisture sensor mayhave to be cleaned and dried, by wiping it with asoft cloth.Floor Protect Pan(Continued next page)ConnectorFloor Protect PanSensor
