The GE Dishwasher H2O error indicates a water supply issue, typically due to insufficient water entering during the fill phase. This can cause the dishwasher to stop early, fail to start the wash cycle, or display the 'H2O' error. Common causes include a turned-off water supply, low water pressure, or obstructions like kinks in the supply hose. Internal components such as the inlet valve or float switch may also be malfunctioning.
