KitchenAid Dishwasher Error F1E1 — What It Means & How to Fix It

What Does This Error Mean?

F1E1 means your KitchenAid dishwasher's main control board has lost communication with the user interface board — the two electronic brains of the machine can no longer talk to each other. This stops the dishwasher from accepting any commands or starting a cycle. The cause is usually a loose wiring harness connector, but it can also be a failed control board or user interface.

Affected Models

KitchenAid KDTM354DSS
KitchenAid KDTE334GPS
KitchenAid KDFE104HPS
KitchenAid KDFM404KPS
KitchenAid KDPM604KPS

Common Causes

Loose or unplugged wiring harness connector between the control board and user interface
Corroded or damaged wiring harness pins causing intermittent signal loss
Failed main electronic control board (ECB)
Failed user interface (UI) board
Power surge or voltage spike that damaged one or both boards

How to Fix It

Press Cancel/Drain to attempt a soft reset. If the dishwasher does not respond, switch off the circuit breaker for the dishwasher for 5 minutes, then switch it back on.

A hard power reset clears transient communication errors caused by power fluctuations.
Run a short test cycle after the reset. If F1E1 reappears immediately, the error is hardware-related and not a one-time glitch.

If the error clears and does not return, the machine is safe to use — monitor for recurrence.
Disconnect power at the circuit breaker, then remove the inner door panel by unscrewing the perimeter screws. Locate the ribbon cable or wiring harness that connects the control board (usually at the bottom of the door) to the user interface (at the top).

Take a photo before disconnecting anything so you know how it reconnects.
Unplug and firmly reseat each connector at both ends of the harness. Look for bent, corroded, or discoloured pins — straighten any bent pins gently with a toothpick.

Corrosion on pins is common in humid environments — light corrosion can be cleaned with electrical contact cleaner spray.
Reassemble the door panel, restore power, and attempt a cycle. If F1E1 is gone, the loose connector was the cause.

A firm connector click confirms the harness is fully seated.
If F1E1 returns after reseating connectors, schedule a professional repair to diagnose and replace the faulty control board or user interface board.

Parts typically cost $80–$200; a technician can usually complete the swap in under an hour.

When to Call a Professional

If reseating the wire connectors does not clear F1E1, one of the two circuit boards has failed and needs to be replaced. Diagnosing which board is at fault requires a multimeter and service manual — a job best left to an appliance technician. Contact KitchenAid service or an authorised repair centre with your full model number.

Frequently Asked Questions

Is F1E1 dangerous — can I keep using the dishwasher?

F1E1 prevents the dishwasher from operating at all, so there is no immediate safety hazard from water or heat. However, do not attempt to bypass the error — the machine should not be operated until communication between the boards is restored.

Could a power surge cause F1E1?

Yes — a voltage spike can damage the delicate communication circuitry on the control board or user interface. If F1E1 appeared right after a storm or power outage, board damage is the most likely cause. Consider using a surge protector on your dishwasher's outlet going forward.

How do I know if the control board or the UI board needs replacing?

A technician will typically swap one board at a time and test after each replacement to isolate the fault. Without specialist diagnostic equipment it is very difficult to tell which board has failed from the outside. Attempting to replace both at once is an expensive guessing game — professional diagnosis saves money.
