GE Dishwasher · Code H2O / H20

GE Dishwasher H2O code: Low or no water

  2. Kinked or pinched inlet hose
  3. Low household water pressure
  4. Dishwasher not level
  5. Faulty water inlet valve

What you can safely check yourself

  1. Make sure the water supply valve under the sink is fully open.
  2. Check the inlet hose for kinks.
  3. Make sure the dishwasher is level.
  4. Clear the code by choosing a different cycle option, then switching back to the one you want.

Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
