Amana Dishwasher Error Code F8 E4 — Drain Pump Failure / Slow Drain
What this means
The F8 E4 error code on Amana dishwashers means the control board detected that water is not draining from the tub within the expected time. The drain pump may be clogged, the drain hose may be kinked or blocked, or the pump motor itself may have failed. Food debris in the sump filter is the most common and easiest-to-fix cause.
Alternate codes: F8E4
Step-by-step fix
4 stepsClean the sump filter and food trap
Open the dishwasher and remove the lower dish rack. Locate the cylindrical filter assembly at the bottom of the tub. Twist it counterclockwise to remove. Rinse both the fine mesh filter and the coarse filter under running water, removing any food particles, grease, or debris.
Amana recommends cleaning the filter at least once a month to prevent drain issues.
Inspect the drain hose
Turn off the circuit breaker. Pull the dishwasher forward and check the drain hose running from the dishwasher pump to the garbage disposal or sink drain. Look for kinks, clogs, or crush damage. Disconnect the hose at the disposal end and blow through it to check for blockages.
If your dishwasher connects to a garbage disposal, make sure the knockout plug inside the disposal inlet was removed during installation.
Clear the drain pump impeller
With the breaker off, remove the lower spray arm and the sump cover to access the drain pump. Check the impeller for foreign objects like broken glass, bones, or plastic bits that may be jamming it. Remove any debris.
Small seeds, olive pits, and toothpick fragments are surprisingly common culprits in dishwasher drain pump jams.
Test the drain pump motor
If the impeller spins freely but the pump still does not run during a drain cycle, the pump motor may be burned out. With a multimeter, test the pump motor for continuity. Replace the pump assembly if it shows no continuity.
A loud grinding or humming noise from the pump before the error appeared usually signals a motor on its way out.
When to call a professional
If the filter, hose, and impeller are all clear and the pump motor has failed, replacing the pump assembly requires removing the dishwasher and accessing the underside. A technician can do this efficiently.
