Most likely causes

  1. Hot water supply valve under the sink not fully open
  2. Kinked, crimped, or partially blocked fill hose
  3. Low household water pressure or a recently shut-off supply line
  4. Clogged inlet screen or a weak water inlet valve
Before you start — unplug the appliance and turn off the water supply. You'll be working near water and electrical parts, and drained water can be hot. If a step involves the pump, wiring, or opening the cabinet and you're unsure, stop and call a qualified technician.

Step-by-step fix

1Open the supply valveFind the hot water shutoff under the sink and make sure it is opened all the way for full pressure.
2Check the fill hoseConfirm the inlet hose behind or under the unit is not kinked, pinched, or crimped.
3Clear the codeSelect a different cycle option and then set it back to your desired setting to clear the H2O display.
4Confirm levelVerify the dishwasher sits level, since tilting can make the fill appear insufficient.
5Call for serviceIf water pressure is good and the valve is open but the code returns, schedule a repair to check the inlet valve.

Still showing H2O?

If you’ve worked through every step and H2O keeps returning, an internal part likely needs testing and replacement. That’s a job for a qualified appliance technician, who can measure the suspect part against the service-manual spec before replacing it.
