But it is very important to follow the exact steps exactly as they are written.

  1. Testing the water pressure

H20 Error Code

Low water flow often makes it so that the dishwasher doesn’t get enough water. When there isn’t enough water flow, the machine can’t fill as quickly and thinks there isn’t enough water.  This is where the h20 error code for ge dishwasher happens most often.

Before you do the test, please make sure you have a pressure measure.


  • Make sure all the taps in your home are turned off.
  • Next, turn on the kitchen tap all the way and hook it up to a Pressure Gauge.
  • After a short break, you should check the water flow.

Please be aware that between 50 and 60 psi is the ideal water pressure for a dishwasher to work well.

  1. Verify the inlet valve

H20 Error Code

The dishwasher’s inlet valve is the main part that helps water get into the machine.  Sometimes it gets clogged or stops working properly over time, so it can’t get enough water to the dishwasher.

The valve can’t be fixed; it can only be changed.


  • Unscrew the Lower Panel of the dishwasher to get it open.
  • Next, open the door of the machine and take the screws out.
  • Take the outside panel off and set it away.
  • Use the main valve to turn off the water line.
  • Unscrew the intake valve and take off the brass elbow.
  • Also, disconnect the wire cable.
  • To get the clamp off, use pliers.
  • Take out the opening that lets air into the unit.
  • Unclog it and look carefully for any problems.
  • If the old outlet valve is broken, set up a new one.
  • Link the filling tube to the valve.
  • Fix the screws in the base of the dishwasher to fix the valve.
  • Wrap Teflon around the elbow of the bass!


  1. Check water hose

H20 Error Code

Over time, the dishwasher line could get clogged, which would make it impossible to get water to the dishwasher. After checking the entry valve, the next step is to look closely at the hose, which could be clogged or leaking. If it breaks, the hose will need to be replaced, which is a cost-effective fix.

Please make sure you’ve done all of the above to get to the water hose and valve.


  • Replace the dishwasher water hose

H20 Error Code

  • First, carefully loosen the screws that hold the Junction Box to the lower panel. Then, remove the bracket that goes with it.
  • Start by carefully untwisting the wires in the junction box. Make sure each wire is free of any tangles and is standing alone. Then, move on to the next step, which is to release the strain relief mechanism. This will relieve any tightness or stress on the wires.
  • To start the process of disconnecting, you have to take the water hose off the sink or the garbage disposer.
  • To start the process, turn the dishwasher’s fastening screws anticlockwise to loosen them. After this step, make any changes to the legs of the unit that are needed to lower the dishwasher to the position you want.
  • Take care to take the unit out of the box.
  • Disconnect the line from the Drain Pump.
  • It is recommended to start the flow of hot water through a hose to help remove debris that is getting in the way.
  • Using a brush to clean the hose for the first time is recommended if you want to get all the dirt out. After that, you should run water through the hose to get rid of any leftover dirt.
  • It is important to check carefully for any possible signs of hose breaking.
  • To make sure the pump works right, it is best to either replace the old hose or connect the pump to the one that is already there.

Once you’re ready, carefully follow the steps in backward order to put all the parts back together. When you turn on the machine, you should no longer see the ge dishwasher h20 error. But if this isn’t the case, please continue with the next steps.

  1. Changing Pressure Switch

H20 Error Code

The dishwasher pressure switch is the next part you need to pay attention to.  The pressure switch in the unit measures how much water it has, but if it’s broken, it won’t be able to tell how much water is in the unit.

To fix the h20 error code for good, all you have to do is change the switch on your GE dishwasher.


  • Stop giving them power and water supply.
  • Disconnect the hose from the sink or garbage disposal and feed it from the closet.
  • Next, take off the screws from the lower access panel and set the bracket away.
  • Use the pliers to take the water pipe part off the valve that lets water in.
  • Take off the cover of the Junction Box and untwist the wires!
  • With a flathead screwdriver, you can release the pressure relief.
  • Next, take out the screws that hold the dishwasher in place, and then lower its legs.
  • Take the unit out of the cupboard.
  • Then turn the unit over and lay it on its back.
  • Take off the cable from the Pressure Switch.
  • To get it out of the box, you need to turn it anticlockwise.

Now you can put in a new pressure switch and reconnect everything in the same way you took them apart.

  1. Verify Float Switch Function

H20 Error Code

The float switch on a ge dishwasher is often used to control the water level, which stops the valve.  Your dishwasher’s float switch may be broken, so it can’t tell how much water is in the unit and the inlet valve can’t fill it with water.


  • Make sure the power and water are turned off.
  • Open the machine’s door and take out the screws from the outside panel.
  • Separate the outer piece carefully and set it aside.
  • Take out the screws on the lower panel!
  • Use Philip’s screwdriver to take out the float switch from inside the tank.
  • Take the wires off the switch and use a multimeter to see if the switch works.
  • If the switch doesn’t work, you need to change the float switch.
  • Put everything back together the right way.

Attention: Make sure to use the multimeter several times before coming to a decision.
