KitchenAid Dishwasher H2O: Check Water Supply Before Restarting
THE SHORT ANSWER
The dishwasher is not detecting water.
H2O means the dishwasher is not detecting water. Start with the water supply and visible hose.
Check that the dishwasher water supply is turned on.
Do not pull out a hardwired dishwasher or open pressurized connections for this check.
WHAT YOU MAY NOTICE
Symptoms to record

Causes & useful observations
A code identifies a condition. It does not, by itself, confirm which part needs repair.
| Possible cause | What to look for | Safe check / next step |
|---|---|---|
| Closed supply valve | Water supply was left off. | Check the accessible valve. |
| Kinked supply hose | An accessible section is visibly bent. | Inspect without disturbing electrical connections. |
