KitchenAid Dishwasher Error Code F9E3 — Diverter Disc Missing or Broken
What this means
Error code F9E3 indicates the diverter disc is missing, broken, or not seated properly in the pump outlet. The diverter disc is a small component that directs water flow between the upper and lower spray arms. If it is missing or damaged, the dishwasher cannot properly distribute water during the wash cycle, resulting in poor cleaning performance.
Alternate codes: F9 E3, 9-3
Step-by-step fix
4 stepsAccess the pump area
Remove the lower dish rack and the lower spray arm by unscrewing or unclipping it. Remove the filter assembly to expose the pump outlet area.
The diverter disc is located in or near the pump outlet beneath the spray arm hub.
Inspect the diverter disc
Use a flashlight to look into the pump outlet for the diverter disc. Check if it is cracked, broken, or missing entirely.
The disc is typically a small round plastic piece — broken fragments may be lodged in the pump area.
Remove broken pieces
If the disc is broken, carefully remove all fragments from the pump area. Even small pieces can jam the pump or diverter motor.
Use needle-nose pliers to extract small fragments if necessary.
Install a new diverter disc
Place the new diverter disc into the pump outlet in the correct orientation. Reinstall the filter assembly and spray arm, then test with a wash cycle.
Ensure the disc seats flat and moves freely — it should not be forced into position.
When to call a professional
If you cannot locate or access the diverter disc, or if replacing it does not clear the error, the diverter motor assembly may need replacement, which requires professional service.
