Whirlpool Dishwasher Error Code F9 E2 — Drain Position Error
What this means
The F9 E2 error code on Whirlpool dishwashers indicates a drain system error that differs from a simple clog (F9 E1). While F9 E1 means water isn't draining, F9 E2 points to abnormal sensor readings in the drain path — the drain pump may be running but the water level sensor still detects water, or the drain cycle timing is outside normal parameters. This can be caused by a faulty drain pump, a defective water level sensor, or an issue with the drain check valve.
Alternate codes: F9E2
Step-by-step fix
4 stepsClear any visible blockages
Remove the lower dish rack and spray arm. Clean the drain filter and sump area at the bottom of the tub. Remove any food debris, glass, or buildup.
The drain filter should be cleaned monthly to prevent buildup.
Check the drain hose and garbage disposal
Inspect the drain hose under the sink for kinks. If connected to a garbage disposal, ensure the knockout plug was removed during installation. Run the disposal to clear any blockages.
A high loop in the drain hose (secured near the top of the cabinet) prevents backflow.
Test the drain pump
Access the drain pump under the dishwasher. Check for obstructions in the pump impeller. Test the pump motor with a multimeter for continuity.
A broken impeller fin can cause the pump to run without actually moving water.
Check the drain check valve
Inspect the check valve in the drain path. It should allow water out but not back in. If it's stuck closed, water cannot exit even with the pump running.
Food debris can lodge in the check valve flapper, preventing it from opening.
When to call a professional
If the pump, check valve, and hose are all clear and the error persists, the water level sensor or main control board may be faulty.
