KitchenAid Dishwasher Error Code F8E1 — Slow Drain
What this means
The F8E1 error code on KitchenAid dishwashers indicates the unit is draining too slowly. Water remains in the tub at the end of a cycle. This can be caused by a clogged drain path, a blocked drain pump, or a malfunctioning drain pump motor. Food debris, broken glass, and grease are common causes of slow drains.
Alternate codes: 8-1
Step-by-step fix
4 stepsClean the drain path
Check for obstructions in the drain path: clean the filter assembly at the bottom of the tub, check the drain hose under the sink for kinks, and run the garbage disposal to clear it.
On new installations, make sure the garbage disposal knockout plug was removed.
Check the air gap
If your sink has an air gap device on the countertop, clean it out. A clogged air gap can prevent the dishwasher from draining.
Inspect the drain pump
If the drain path is clear, the drain pump may be weak or obstructed. Listen during a drain cycle — you should hear a humming motor. If silent, the pump may have failed.
Replace the drain pump if needed
If the pump is not running or is very weak, replace it. Check the wiring first to make sure it's getting power.
When to call a professional
If cleaning everything doesn't resolve the slow drain and the pump runs, there may be an issue with the drain valve or control board.
