Whirlpool Dishwasher FA E4 Error Code: Door Switch and Motor Fault

Quick Answer

FA E4 on a Whirlpool dishwasher combines the door circuit (FA) with the motor control fault (E4). The most common cause is a failing door latch assembly that intermittently signals the door as open while the wash cycle is running, causing the control board to halt the motor as a safety response. On the WDT series, the door latch includes a microswitch that wears over time.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

1

With the dishwasher running a cycle

With the dishwasher running a cycle, gently push and pull on the closed door to simulate vibration. If FA E4 appears when you flex the door, the latch microswitch is intermittent under mechanical movement.

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

Why does FA E4 appear more often during heavy cycles?
Heavy cycles create more vibration. A marginally worn door latch microswitch that holds a reliable connection at rest can break contact when the machine vibrates, triggering FA E4. Replacing the latch resolves this.
