KitchenAid F8E5 Error Code: Inlet Valve Stuck On
High severity
Where F8E4 means water was found somewhere it shouldn't be, F8E5 means the opposite kind of problem: the valve that lets water into a KitchenAid dishwasher won't stop letting it in.
Applies to: KitchenAid dishwashers with electronic controls and a solenoid-operated water inlet valve.
What it means
The inlet water fill valve is stuck open (stuck on), so the control board triggers a drain sequence and prevents further operation to avoid overfilling.
The water inlet valve is a solenoid, an electrically operated gate that's supposed to snap shut the instant the control board decides the fill is complete. A flow meter downstream counts pulses as water passes through, and F8E5 appears specifically when that meter keeps counting pulses after the valve was told to close, which only happens if the valve itself is physically stuck open or something inside it is holding it there. Rather than let the tub keep filling toward an overflow, the control board immediately starts a drain sequence and locks the dishwasher out of normal operation until the fault is cleared.
Common causes
The list here stays narrow, since there are really only two ways a fill solenoid fails in the open direction:
- A stuck-open water inlet fill valve/solenoid
- Debris holding the valve open internally
What you can check yourself
The order of these steps matters more than usual, because water may still be actively flowing while you're reading this:
- If you can safely reach it, turn off the water supply to the unit; if you cannot turn off the water, do not cut power and keep the door closed to avoid a spill
- Once water is off, unplug the dishwasher (or flip its breaker) for 30 seconds, then restore power
- Turn the water supply back on and run a normal cycle to see if the fault clears
Notice that step one is about the water, not the power — the instructions specifically warn against cutting electricity before the water supply is off, because a de-energized valve can behave unpredictably and the alarm needs to stay live to keep the door sealed against a spill. Once the supply is shut and the reset is done, whether the valve holds closed on the next fill tells you immediately whether the fix worked.
Call a professional when
A stuck-open fill valve is a parts-level failure. If the reset doesn't resolve it, the inlet water valve needs professional inspection and likely replacement.
