KitchenAid Dishwasher F9 E1 Error Code

KitchenAid identifies F9 E1 as a long-drain condition. Its homeowner guidance focuses on the removable filter, visible drain hose, disposer knockout plug on new installations, air gap where used, and excessive suds before service is considered.

Applies to KitchenAid dishwasher using the documented F/E or H2O display family

What the appliance detected

Detected condition

The dishwasher reports a long-drain or not-draining condition.

What may contribute

Possible causes

  • The removable filter may be clogged.
  • The visible drain hose may be kinked, pinched, or restricted.
  • A new disposer connection may still have its knockout plug installed.
  • An air gap may be blocked where one is installed.
  • Excess suds or an internal drain-pump, hose, wiring, or control problem may keep the dishwasher from draining normally.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the code and check standing water safely

    • Photograph F9 E1 and confirm the model number.
    • If water is standing in the tub, keep hands away from electrical areas and disconnect power before owner-accessible wet-area checks.

  2. Clean the owner-accessible filter

    • Remove and rinse the filter only if the exact owner manual identifies it as removable by the user.
    • Reinstall it fully and correctly before testing another cycle.

  3. Inspect the visible drain path

    • Check the visible drain hose for a kink or pinch.
    • If connected to a recently installed disposer, confirm the disposer inlet was properly opened by the installer; if an air gap is present, follow its documented cleaning instructions.

  4. Use one documented power cycle only if needed

    • KitchenAid documents a 30-second power cycle for the dishwasher control.
    • If F9 E1 returns after the accessible drain checks, stop repeating resets and request service.

Actions not recommended

  • Do not open the drain pump, sump, wiring, or control areas.
  • Do not use drain chemicals in the dishwasher.
  • Do not replace the drain pump from F9 E1 alone.

When to stop and request service

  • F9 E1 returns after the accessible filter, hose, disposer, and air-gap checks.
  • Standing water cannot be addressed safely or the dishwasher is leaking.
  • Internal pump, hose, wiring, or control diagnosis is needed.
