KitchenAid Dishwasher Code F6E4: water float switch

What F6E4 means

On KitchenAid built-in dishwashers with the F#E# control, such as the KDTE204KPS and KDPM604KPS, F6E4 is tied to the water float switch. The float tells the control whether water in the base is at a normal level. You see F6E4 on the display and the cycle stops. The first steps are to level the dishwasher and cycle the power. The dishwasher will not continue the cycle.

Common causes of F6E4

The float switch is not moving freely or is not reporting correctly.
The dishwasher is not level, so the float behaves oddly.
A wiring or control issue affecting the float switch signal.

✓ One safe check you can try

1. Open the door and look at whether the dishwasher sits level front to back and side to side. 2. If it does not, call us rather than moving it yourself. 3. Switch off the dishwasher breaker for 30 seconds, then flip it back on. 4. Run a short cycle. 5. If F6E4 returns, stop and call.

! Why to stop there

The float and its wiring need a proper test.
An unlevel machine may need adjusting with the right tools.
Our estimate is on paper first, the work covered 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.

F6E4F6E4 questions

What is the float switch?

A small switch in the base that rises and falls with the water level. It tells the control whether the level is normal, and F6E4 appears when its signal is wrong.

Why does leveling matter?

If the dishwasher tilts, the float may stick or read wrongly. Leveling is the published first step, along with cycling power. A level base keeps the float moving freely.

Can you fix this on site?

Usually yes. We test the float and its connection, quote in writing before work, and warrant our repair for 30 days. Most float problems are solved in a single appointment.
