KitchenAid Dishwasher Error Code F8E2 — Drain Pump Electrical Problem
What this means
Error code F8E2 indicates an electrical problem with the drain pump. The control board is unable to properly power or communicate with the drain pump motor. This can be caused by a failed drain pump motor, a broken or corroded wire connection, or a faulty control board relay. The dishwasher may fail to drain, leaving standing water in the tub.
Alternate codes: F8 E2, 8-2
Step-by-step fix
4 stepsPower cycle the dishwasher
Turn off the circuit breaker for 5 minutes, then restore power. Start a drain cycle to see if the pump activates.
Listen for the pump motor — you should hear a humming sound if it is receiving power.
Check the drain pump wiring
Disconnect power and access the drain pump under the dishwasher tub. Inspect the wiring harness for loose, damaged, or corroded connections.
Have towels and a shallow pan ready — there may be standing water when you access the pump area.
Test the drain pump motor
Use a multimeter to check continuity across the drain pump motor terminals. A reading of OL (infinity) means the motor winding is open and the pump needs replacement.
Expected resistance is typically 5-20 ohms for a working drain pump motor.
Replace the drain pump
If the pump motor tests faulty, disconnect the wiring harness and water connections, remove the mounting hardware, and install the new drain pump.
Ensure the drain hose is properly reconnected and secured with a hose clamp after installation.
When to call a professional
If the drain pump and wiring test good but the error persists, the control board relay may be faulty. Professional diagnosis is recommended to confirm before replacing the board.
