(469) 638-3215F8E5 is one of the few KitchenAid dishwasher codes that needs action right away. KitchenAid ties it to a fill valve stuck open, which can keep feeding water into the machine.
KitchenAid lists the potential cause of F8E5 as “Fill Valve Stuck Open.” The water inlet valve should close once the tub has enough water; when it doesn’t, water keeps coming in. KitchenAid’s instructions are specific: shut off the water to the dishwasher if you can, press Cancel once to silence the alarm, close the door and keep it closed, and leave the power on. Only if you can’t shut off the water should you turn the power off. Source: KitchenAid F8E5 (opens in a new tab).

KitchenAid names the valve; a technician confirms why it stuck.
Follow these exactly. They differ from most dishwasher codes.
Close the valve that feeds the dishwasher, usually the hot water valve under the kitchen sink.
Press Cancel once to stop the alarm, then shut the door and keep it closed. KitchenAid says not to turn off the power at this point.
KitchenAid’s fallback is to turn off the power to the dishwasher instead. Then towel up any water and keep children away from wet floors.

We test the inlet valve and its control signal, replace what failed and run a full fill to confirm it closes. You get a written estimate first. After-hours visits cost extra.

That is the order KitchenAid gives: shut off the water, silence the alarm, close the door and leave the power on. Its article makes cutting power the fallback for when the water can’t be shut off, so follow it in that order.
Not until the valve is checked. A valve that stuck once can stick again and overfill while nobody is watching.
No. F8E4 means water was found in the drip tray. F8E5 points to the fill valve stuck open. Both involve water where it shouldn’t be.
In most DFW kitchens it is a small valve on the hot water line under the sink. Turn it clockwise to close it.
