KitchenAid Dishwasher Code F8E4: water in the base, drain sequence runs

What F8E4 means

KitchenAid built-in dishwashers with the F#E# control, including the KDTM404KPS and KDFE104HPS, report F8E4 when water is found in the base. The drain sequence starts, and the machine will not operate. The display shows F8E4. The published checks are the water supply connection, that the float switch is connected, and an empty drip tray. The dishwasher will not accept a new start until the situation is resolved.

Common causes of F8E4

A leak from the supply connection into the base.
The float switch is disconnected or not reporting correctly.
Water has collected in the drip tray or base area.

✓ One safe check you can try

1. Turn off the water supply. 2. Let the drain sequence finish with the door closed. 3. Check the supply connection under the sink and behind the dishwasher for drips. 4. Dry the area around the base. 5. Restore water, run a short cycle, and call us if F8E4 returns.

! Why to stop there

Water in the base means a leak or a sensor problem that will not cure itself.
Hidden leaks quietly harm cabinets.
The estimate is put in writing and the repair is guaranteed for 30 days.

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.

F8E4F8E4 questions

Why does it drain when F8E4 shows?

The dishwasher found water where it should not be and begins draining as a protection. It also blocks operation until the problem is dealt with.

What should I look at first?

The supply connection, the float switch connection and any water in the tray under the dishwasher. Dry everything and try again. Tracing it may mean looking behind the kick plate.

When do you come out?

When F8E4 returns after those checks. We trace the leak or sensor issue, quote in writing, and warrant our repair for 30 days. Quotes in writing mean no surprises on the bill.
