GE Dishwasher Error Code: C5
Be sure the water supply valve to the dishwasher is completely open. Be sure the overfill float switch is not stuck in the up position as this will prevent the dishwasher from filling with water. Remove the dishwasher from power and turn off the water supply valve. Remove the water fill line and check the water inlet valve. If the inlet screen is blocked or has clogs then replace the water inlet valve as only cleaning the screens is not enough and can cause flooding. Check the wiring harness on the water inlet valve to be sure there are no loose wires. If you find that the water inlet valve does not open when power is applied then replace it.
