What F8E5 Means
Dishwasher: KitchenAid publishes F8E5 as "Potential Cause: Fill Valve Stuck Open", and the steps it prints are not diagnostic steps - they are containment. Turn the water off to the dishwasher if you can. Press the Cancel key once to silence the alarm, then shut the door, and specifically do not turn the power off and keep the door closed. Only if you cannot turn the water supply off does KitchenAid tell you to cut power to the machine. That order is the whole message of this code: a valve that will not close is admitting mains water into the tub continuously, and the machine needs to keep draining while you stop the water at the source.
Common Causes of F8E5
- The fill valve mechanically stuck open by debris or a failed solenoid
- A valve that has been energized long enough to fail in the open position
- Grit from the household supply lodged on the valve seat
🔧 One Safe Check You Can Try
Shut the supply valve to the dishwasher first - it is usually under the sink on the hot line. Press Cancel once to silence the tone, close the door and leave the power on so the machine can carry on draining, exactly as KitchenAid instructs. Only if the supply valve is seized or you cannot find it should you cut power at the breaker instead, and in that case the water must be stopped at the house shut-off. Do not run another cycle, and do not leave the house with the supply still open.
⚠ Why You Shouldn't Go Further Than That
- A valve stuck open is fed by household water pressure, so the volume it can put into a kitchen in a few unattended hours is limited only by how long it takes someone to come home.
- The valve sits in the wet base of the machine on a pressurised fitting with live wiring alongside, and unscrewing it without the supply shut and the power off means water under pressure meeting an energized terminal.
- Stopping the machine draining, by cutting power while the tub is still filling, removes the only thing keeping the water level under control.
