KitchenAid Dishwasher Code F8E1: not detecting water, same as H2O

What F8E1 means

On KitchenAid built-in dishwashers with the F#E# control, such as the KDFE104HPS and KDPM604KPS, F8E1 is the digital form of the eight-then-one blink and appears as H2O on some models. The dishwasher is not detecting water. You see F8E1 and the fill step waits. Make sure the water supply is on and the hose has no kinks, then press Start and it will attempt to fill.

Common causes of F8E1

The water supply valve is closed or partly closed.
The supply hose is kinked.
The fill valve or the water sensing is not working.

✓ One safe check you can try

1. Make sure the valve under the sink is fully open. 2. Straighten any kink in the supply hose. 3. Run the kitchen faucet to confirm good flow. 4. Close the dishwasher door and press Start. 5. If F8E1 appears again, call us.

! Why to stop there

A closed valve costs nothing to open.
If water arrives and F8E1 stays, the fill valve or sensing needs a test.
You see the estimate in writing before we start; repairs have 30 days of warranty.

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.

F8E1F8E1 questions

Does H2O show up instead of F8E1 on some models?

Yes, the same condition appears either way: the dishwasher is not detecting water. Some models spell it F8E1, others H2O, and LED models blink eight then one.

How do I make it resume?

Restore the water supply, straighten the hose and press Start. The dishwasher will attempt to fill and continue the cycle. Many people find the valve was simply half closed.

When do I call you?

When the water is on and the hose is clear but F8E1 returns. The fill path gets tested, and the written quote comes before any work. We then check the inlet screen as well.
