Direct answer
On the covered KitchenAid dishwasher, F8 E4 means water was detected in the base or drip tray, or an overfill condition is present. KitchenAid's page begins by asking whether the dishwasher was newly installed. First, check the water supply connection, float switch and drip tray; check for excessive suds.

Preserve the failure state
ReversibleCheck the water supply connection, float switch and drip tray; check for excessive suds. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversibleCorrect an installation or suds cause; arrange service for a genuine leak. KitchenAid documents these checks for this code: was the dishwasher newly installed; do you see water; and are there excessive suds. Work them in that order and correct only what you actually find.
Verify once, then respect the service boundary
ReversibleRepeat only the shortest safe action that reaches the original stage. If F8 E4 returns, stop repeated resets and use model-specific manufacturer support.
