H2O on a KitchenAid dishwasher means no water is detected. The manufacturer's checks are the supply and the hose.
Model compatibility: KitchenAid reuses codes across series and model years, so H2O may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
What this code means
Dishwasher is not detecting water; check that the water supply is turned on and the supply hose is free of kinks.
If the display of a KitchenAid dishwasher reads H2O, the machine is not detecting water. You may also meet the spelling H20 in KitchenAid’s pages. Both point to one entry.
At a glance
| Code | H2O |
|---|---|
| What it means | Dishwasher is not detecting water; check that the water supply is turned on and the supply hose is free of kinks. |
| What you can check | Make sure the water supply to the dishwasher is turned on and look along the supply hose for kinks. Once that is fixed, press Start so it can fill and continue. |
| When to call a technician | If the supply and hose look fine and H2O shows again, schedule a service visit. Tell the technician whether the valve was open and whether any water entered. |
Only two items on the list
- Turn the water supply to the dishwasher on, if it is not already.
- Look along the supply hose for kinks.
KitchenAid repeats exactly these two checks on both of its pages. The articles do not describe a reset, a filter check or a look at the drain.
Resuming the cycle
One of the two articles pairs H2O with F8E1. It tells you to press Start once the supply has been fixed, after which the dishwasher attempts to fill and continue the cycle.
Where H2O sits next to the F6 entries
H2O has an owner fix in an owner-help article. By contrast, the F6 entries in the technician documents (low or no water, fill valve electrical problem, cool water) list parts and are not written for households. A supply and hose that look fine, followed by another H2O, means scheduling service.
Useful facts for the technician
- Whether the supply valve was open when H2O appeared
- Whether the hose looked straight
- Whether any water entered the dishwasher
