Indeed, General electric washing machines are highly reliable. Part of this reliability is their ability to promptly call your attention to minor problems, which can quickly snowball into more prominent and challenging to tackle.

General electric washing machine error codes pop up at the most unexpected times, just as you have it now or might have later. 

The onus now lies in you interpreting the problem correctly and proffering an appropriate solution to the problem indicated by the washing machine error code.

So pay close attention to the ultimate fix for this all-common GE washer error code. 

A GE H20 supply error code indicates that the washer senses inadequate water filling in the washer’s chamber. This is usually due to a compromised water supply volume secondary to a blockage or closure of the water inlet valve or faulty water inlet hoses.

What Does H20 Supply Mean on a GE Washer?

This washing machine error code indicates a few things depending on the GE washer model you are using.

First, for one reason or another, the water inlet valve or water inlet hoses are not supplying an adequate volume of water to the washer, hence, the washing machine error code. 

However, a thorough inspection of the water valve and inlet hoses shows they are good enough to supply water to the GE washing machine.

Therefore, the problem might be due to a faulty circuit board. This board coordinates the various activities of the washer. 

Once there is a problem on the board concerning the coordination of any of the functions, it initiates the display of washer error codes peculiar to the role they perform.

Thus, the underlying problem might be the circuit board itself, not the water inlet valve or water inlet hoses.

Furthermore, the problem prompting this GE washing machine error code could be the main water supply from your residential tank.

You might have cut off the supply of water from the tank itself. Thus, water would not be available to the GE washing machine, hence the error code.

How Do You Clear the Error Code On a GE Washing Machine?

First and foremost, diagnosing the underlying condition responsible for the washing machine error code is essential.

In this case, the practical test would aid accurate diagnosis is the T06 pressure switch test.

To get into the test mode, press the washing machine power button for about ten seconds while rotating the selection knob; the machine would switch to the test mode.

All details on how to run this diagnostic test are detailed in the user manual packaged with your General electric washer. 

If the T06 pressure switch test is positive (i.e., water starts filling the GE washing machine), the problem is neither coming from the water inlet valve nor the water inlet hoses.

Instead, the issue to be fixed most likely lies outside the GE washing machine. The main water supply or the circuit board most likely is the problem’s source.

Once you have been able to proffer an adequate solution to the underlying problem, washer error codes of this sort would disappear.

Once again, you would use the GE washing machine without such promptings and error codes.

How Do You Clean the Filter On a GE Washing Machine?

Keeping the filter clean at all times is very important to preventing pop-ups of several washer error codes.

This is especially water supply error codes which would most likely pop up when the filter leading to the water inlet valve and water inlet hoses have been clogged up with a build-up of dirt.

Find below an outline on keeping the filter clean on GE washing machines.

  • Switch of the GE washing machine and disconnect from the mains power supply
  • Turn off the main water supply connected to the GE washer 
  • Pull off the water inlet valve and water inlet hose from the main water supply
  • Drain all the residual water from the water inlet hose
  • Detach the water inlet valve from the GE washer’s back panel. On some models, you would have to unscrew in the anti-clockwise direction to loosen and disconnect the water inlet hose and water inlet valve from the GE washer. Handle very carefully to avoid displacement of the rubber washer inside this water inlet valve 
  • At this point, the filter is exposed to the body of the GE washer. You have removed the water inlet valve and inlet hose from the spot.
  • Now, pull out the filter from its holder.
  • Clean both the inner and outer portions carefully and thoroughly under clean running water
  • After proper, thorough cleaning, the filter should have a bright and clean metallic appearance.
  • Now, re-insert into its original position on the GE washer’s back panel
  • Reconnect the water inlet valve and water inlet hose by screwing in the clockwise direction until the connector knob fits perfectly into position
  • Reconnect the other end of the water inlet valve and water inlet hose to the main water supply. Switch on the water supply to enable water flow to the GE washing machine.

Ensure you turn on the main water supply after all the above procedures have been duly observed. 

Furthermore, if the water inlet valve filter gets clogged up with dirt too often, it is advised that you check your primary source of water supply.

The main tank might need to be correctly washed to reduce the load of dirt transferred to the GE washing machine. 

How To Reset GE Washing Machine?

In some cases, restoring default settings on the GE washing machine is essential.

Find below an outline on how to properly reset a GE washing machine.

  • Ensure the system boots properly. To do this, unplug the machine, wait for 15 seconds, then plug it into the main sockets again. Finally, allow the device to boot correctly.
  • Now, lift and lower the lid six times within a time limit of twelve seconds. Ensure the raised to a height of at least 2″.

    This would ensure that the cover disconnects temporarily from the magnetic pool of the lid’s sensor. Also, ensure the lid is closed correctly when the top is returned to a closing position.
  • The GE washer motor and central control system have been reset by now.

However, always consult your user manual to confirm which reset method works best for your GE washing machine model. 

Before you initiate a reset on the GE washing machine, ensure the underlying problem is not related to hardware issues.

These issues include leaking or faulty water inlet valves and water inlet hoses, improperly screwed water inlet valves, and unavailability of water from the primary water supply source.

You can quickly fix all these problems by addressing the issues themselves and finding a solution. Once the key is proffered, there might not be a need for a GE washing reset.

In essence, only initiate GE washing machine rest when there are no other options. Consider it a weapon of last resort!


GE washer H20 supply errors are mainly due to clogged water inlet valve filters, faulty water inlet hoses, accidental breaking of water supply from the public water supply source in the home, or defective circuit boards in GE washers.

There is an adequate washing machine power supply, the water inlet valve and water inlet hoses, and an uncompromised general water supply.

So, washer error codes about H20 supply errors can only be due to a clogged filter or a damaged circuit board.

Once all the above have been examined and found in top shape, You would resolve GE washing machine error codes bordering around water supply.
