What error code F6E4 means on a KitchenAid HE dishwasher

This is a sensors code. Codes and wording can vary by model, so check your owner's manual for your model number.

How to fix KitchenAid HE dishwasher error code F6E4 (safe owner checks)

Safety first: disconnect power before you remove any panel or reach into the sump or drum. Do not touch wiring, the control board or the motor. If you see water near electrical parts, stop and call a technician. These steps are based on the KitchenAid HE dishwasher error-code chart (via Sears PartsDirect) [1], rewritten for clarity.

Write down the code and model number. Note exactly what the display shows (F6E4) and copy the full model number from the rating label, so you can confirm this chart applies to your HE dishwasher and order the right parts.
Reduce the load. Check the overfill float switch to see if it's stuck or if an item is stuck under it.
Open the water supply. Check if the inlet water fill valve is properly shutting off the water supply when the dishwasher is off.
Do a power reset. Unplug the appliance or switch off its breaker for one minute, then restore power and try again. If the code clears and stays away, it may have been a one-off fault.
Test and decide. Run a short cycle or restart and watch the display. If F6E4 comes back after these checks, stop using the dishwasher for this function and call a technician, because the remaining causes need meters or part replacement.

The first and last steps (and the power reset) are general owner checks added by ErrorCodePro; the rest follow the KitchenAid HE dishwasher error-code chart published by Sears PartsDirect, rewritten for safe owner use.
