Fisher & Paykel Dishwasher Error Code E1

The E1 code means the dishwasher has detected water in the base pan of the unit, which is the area beneath the tub. A flood sensor located in the base has been triggered, causing the machine to stop operation as a safety precaution. The error will remain active until the source of the water intrusion is identified, the leak is repaired, and the standing water is removed from the base.

No, you should not attempt to run the dishwasher while the E1 error is active. The machine has shut down specifically to prevent water damage and potential electrical hazards from water contacting internal components. The dishwasher should remain off until the leak is located and fully resolved.

Repair costs vary depending on the cause. Replacing a door gasket is typically one of the less expensive fixes, often falling in the range of $50 to $150 for parts and labor. A pump seal or inlet valve replacement may range from $100 to $300 or more depending on parts availability and labor rates in your area. Diagnosing the exact source of the leak is the critical first step before any cost estimate can be made.

Start by pulling the dishwasher forward enough to access the base and check for visible standing water. Identify the source of the leak by inspecting the door gasket, all hose connections, the pump, and the inlet valve. Once the faulty component is repaired or replaced, dry out the base pan completely and restart the unit. If you cannot locate the source of the leak, a technician should perform a more thorough inspection with the machine running.

A reset will not permanently clear the E1 error if water remains in the base pan or if the underlying leak has not been repaired. The flood sensor will re-trigger as soon as the machine attempts to fill or run. The base pan must be dried out and the source of the water intrusion fixed before the error will clear and stay clear.
