How to fix KitchenAid F6E4

  1. Check that the unit is level

    Set a level, or a phone level app, on the open door and on a rack rail. If it's off, switch off the power and adjust the leveling legs until the bubble is centered side to side.

  2. Power it down and back up

    Give the control its 30 seconds without power, then try again.

When to call a technician

If the dishwasher is level and F6E4 keeps coming back, have a technician check the float switch and its wiring.
