GE Dishwasher · Code C6

GE Dishwasher C6 code: Water too cold

The water coming into the dishwasher isn't hot enough. GE wants incoming water at about 120°F for good cleaning.

Most common causes

  1. Water heater set too low
  2. Long pipe run from the water heater, so the first water in is cold
  3. Dishwasher connected to the cold line
  4. Heating element or temperature sensor problem

What you can safely check yourself

  1. Run the kitchen faucet until the water is hot before starting the dishwasher.
  2. Check that the home water heater is set to deliver about 120°F.
  3. Choose a cycle or option that adds heat, if your model has one.

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