JennAir Dishwasher F9 E1 Error Code

F9 E1 is one of the more homeowner-checkable JennAir dishwasher codes. Start with the accessible filter, visible drain hose, disposer inlet or air gap, then use one documented 30-second power cycle only after the drain path is corrected.

Applies to JennAir dishwasher with F-E error-code display or flashing status light

What the appliance detected

Detected condition

The dishwasher did not complete draining within the expected time.

What may contribute

Possible causes

  • The accessible filter may be restricted with food or debris.
  • The drain hose may be kinked, pinched, clogged, or installed incorrectly.
  • A new disposer connection may still have its knockout plug in place, or an air gap or sink drain may be blocked.
  • An internal drain-pump, control, or wiring issue may remain if external checks are clear.

Start conservatively

Safe preliminary checks

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

  1. Clean the owner-accessible filter

    • Turn the dishwasher off and use the model manual to remove only the filter intended for routine cleaning.
    • Rinse the filter under running water, reinstall it correctly, and do not reach into pump or electrical areas.

  2. Check the visible drain route

    • Inspect the visible drain hose for kinks, pinches, or obvious blockage.
    • If connected to a disposer, confirm the disposer is clear and that the inlet knockout plug was removed during installation. If an air gap is used, follow its manufacturer instructions for accessible cleaning.

  3. Power cycle once after correcting the drain path

    • Disconnect power for 30 seconds only after any visible obstruction or routing problem is addressed.
    • Restore power and try normal operation once. If F9 E1 returns, schedule service rather than repeatedly resetting it.

Actions not recommended

  • Do not disassemble the drain pump, sump, motor, or internal drain plumbing.
  • Do not reach into a disposer unless it is safely de-energized and its own instructions allow the check.
  • Do not repeatedly reset F9 E1 without correcting a visible drain problem.

When to stop and request service

  • F9 E1 returns with a clean accessible filter and clear visible drain path.
  • Standing water cannot be removed safely or an internal obstruction is suspected.
  • The next step would require pump, wiring, control, or internal hose diagnosis.
