KitchenAid Dishwasher Error Code F8E5

F8E5 means the control board detected water flowing through the flow meter while the fill valve was commanded to be off. This indicates either a fill valve that is stuck open and cannot stop water from entering the tub, or a shorted TRIAC on the control board that keeps the fill valve energized. The dishwasher stops operation to prevent overfilling and potential flooding.

No, it is not safe to continue running the dishwasher with this fault active. An F8E5 code signals uncontrolled water flow that can lead to tub overflow and water damage to your floors and cabinetry. Keep the dishwasher off and the water supply valve closed until the fill valve or control board has been inspected and repaired.

If only the fill valve needs replacement, parts typically range from $20 to $60 depending on the model, and professional labor adds $80 to $150 in most markets. If the control board is the cause, the board itself can range from $100 to $250 or more, making total repair costs potentially $200 to $400 with labor. Getting a diagnosis first to confirm which component has failed can help avoid replacing unnecessary parts.

Start by opening the door during a fill cycle to see if water continues to enter the tub. If it does, unplug the dishwasher, shut off the water supply, and replace the fill valve. If filling stops when the door is opened but the fault appears during a normal cycle, the control board is the likely cause and will need to be replaced. Do not attempt repairs with the dishwasher plugged in or the water supply active.

A reset may temporarily clear the code from the display, but it will not fix the underlying hardware failure. If the fill valve is stuck open or the TRIAC is shorted, the fault will return as soon as the dishwasher attempts another fill cycle. A reset should only be used as part of diagnosis, not as a solution.
