KitchenAid Dishwasher Code F4E3: heating error during the cycle

What F4E3 means

KitchenAid built-in dishwashers with the F#E# control, including the KDPM604KPS and KDFE104HPS, show F4E3 for a heating error. The control found a problem with how the water is being heated, and the cycle stops. You see F4E3 on the display. A power cycle is the first step; if it returns, the heating circuit needs attention. F4E2 is a related heating code.

Common causes of F4E3

A heating circuit problem the control detected.
The heating element is not working correctly.
A sensor or control issue that affects heat regulation.

✓ One safe check you can try

1. Switch off the breaker for about 30 seconds, then restore power. 2. Shut the door firmly and begin a short test cycle. 3. Make sure hot water reaches the dishwasher. 4. Do not run repeated long cycles if the code returns. 5. Call us if F4E3 appears again.

! Why to stop there

A heating error can leave dishes dirty and damp.
Testing shows whether element, sensor or control is to blame.
We give the price in writing; 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.

F4E3F4E3 questions

How is F4E3 different from F4E2?

Both involve heating. They are separate codes, so we read which one appears and test the heating circuit with that in mind. We read the exact code on the display before starting.

Can I keep using the dishwasher?

If F4E3 clears after a power cycle and stays gone, yes. If it returns, avoid repeated cycles and book a diagnosis. It helps you see which heating step went wrong.

What will you test?

The heating circuit and its sensing, with a meter. We explain what we find and quote in writing before we repair anything. Sensing parts are checked beside the heater.
