However, if the error code appears on the1 hour wash cycle, you should contact a professional to repair the dishwasher.

If it appears in other wash cycles, a careful inspection of the water source and inlet valve will clear the error codes and help you identify the cause.

Also, the H20 error code often appears:

  • If you have recently purchased the dishwasher,
  • You are running the device for the first time,
  • If you have recently repaired your plumbing,
  • You recently cut off the water supply.

The following are the underlying causes of the H20 error code on your GE dishwasher:

#1.faulty inlet valve

The water inlet valve controls how much water fills the dishwasher and the timer controls it. It's faulty if it doesn't respond when you turn on the timer.

Open the bottom access panel to locate the inlet valve and verify that it works.

Also, if the inlet valve does not have enough water pressure, your inlet valve could be the cause of the error code being displayed.

#2.Defective or twisted hose

If the inlet hose is faulty, it will not allow enough water to flow into the dishwasher's chamber, hence the H20 error code.

The error code display can also be caused by a kinked or kinked hose. In this case, the hose will restrict the flow of water into the chamber due to its incorrect placement.

  • A faulty circuit board or

  • Check the bottom left of your dishwasher to locate your machine's water inlet valve.
