KitchenAid Dishwasher H20 Code: No Water Detected
Updated
Short answer
What H20 means
In KitchenAid's words, condensed: the dishwasher is not detecting water (KitchenAid).
What KitchenAid says to try
- Make sure the water supply to the dishwasher is turned on.
- Check the water supply hose for kinks.
Unplug the appliance or switch off its breaker before reaching into any part of it. Codes and steps vary by model, so check your manual too.
If the code comes back
With the water on and a straight hose, the inlet valve is the next thing to check. Dishwasher hose replacement runs $75 to $130; water line replacement $100 to $200. (Angi, dishwasher repair cost (updated Apr 6, 2026))
