What does KitchenAid F8E4 mean?

The diverter disk motor, which directs water between the lower spray arm and the upper/middle spray arms in sequence, has stalled or failed to reach its target position.

What causes KitchenAid F8E4?

  • Foreign object (broken glass, food bone) lodged in the diverter disk
  • Failed diverter motor
  • Diverter position sensor failure

How to fix KitchenAid F8E4 yourself

  1. 1 Remove both racks and inspect the bottom of the tub for broken glass or hard debris — this is the most common cause.
  2. 2 Remove the lower spray arm and clean around the diverter disk area.
  3. 3 Run a reset: power off at the breaker for 5 minutes, then restore power and run a normal cycle.
