KitchenAid Dishwasher Code F9E1: long drain, check filter and hose

What F9E1 means

KitchenAid built-in dishwashers with the F#E# control, such as the KDTM404KPS and KDFE104HPS, show F9E1 for a long drain. The dishwasher is taking too long to pump water out. You see F9E1 on the display, and there may be water standing in the tub. The checks are the filter, the drain hose, the disposer knockout plug and the air gap, then a power cycle.

Common causes of F9E1

A clogged filter in the bottom of the tub.
A kinked or blocked drain hose.
A disposer knockout plug that was never removed, or a clogged air gap.

✓ One safe check you can try

1. Remove the lower rack and rinse the filter under running water. 2. Look behind the dishwasher for a kink in the drain hose. 3. Run the disposer empty if you have one. 4. Clean the air gap on the sink, if present. 5. Turn off power for 30 seconds, restore it and run a short cycle.

! Why to stop there

A plain clog is likely and may be solved at home.
A weak pump needs tools and testing.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F9E1F9E1 questions

What causes F9E1?

Water leaves the tub too slowly. A dirty filter, a kinked hose, an unremoved knockout plug or a clogged air gap are the usual causes.

Does the nine-then-one blink mean F9E1?

Yes. LED models flash nine times, pause, then one time, to show the same code that digital models spell out. Both are quick checks you can do while the dishwasher rests.

When should I call?

If the filter, hose, disposer and air gap are clear and F9E1 still returns. We test the drain pump and quote in writing before we start.
