8-1 — (F8E1 / H2O) Error — Not Detecting Water
8-1 — shown as F8E1 or H2O on models with a display, or as the Clean light flashing 8 times, pause, 1 time — means the dishwasher is not detecting water coming in during the fill step. KitchenAid's published guidance: make sure the water supply is turned on and the line is not kinked, then press Start/Resume. Note: some older service charts list 8-1 as a slow-drain error — KitchenAid's current documentation assigns it to water-fill detection, and this page follows KitchenAid.

How to fix it
- Check the under-sink water supply valve is fully open and the supply line has no kinks.
- Press Start/Resume — per KitchenAid, the dishwasher will attempt the fill again once water is available.
- If it still will not fill, power off at the breaker for 5 minutes and retry once.
- If 8-1 returns with the supply confirmed on, the water inlet valve is the usual suspect — replace it or have it serviced.
Why it happens
Typical signs: Clean light flashing 8-1 (8 flashes, pause, 1 flash), or F8E1 / H2O on the display · Dishwasher hums or waits at the start of the cycle but never fills · No wash action
- Water supply off or restricted The under-sink shutoff valve is closed or partially closed, or the supply line is kinked. The most common and cheapest outcome.
- Water inlet valve not opening The electrically operated fill valve on the dishwasher can fail closed, so no water enters even with the supply on.
