General Electric dishwashers are popular for two key features of appliances—their ability to produce top quality and beautiful appliance designs.
These designs also come with an efficient error detection system that calls your attention when there are issues like the H20 error in the dishwasher.
However, after detecting the error code, you might have some difficulty interpreting the code.
Therefore, you must determine the error’s meaning to identify the problem’s cause and fix it promptly.
The H20 error code on your GE dishwasher indicates that the machine is not getting enough or no water into its chamber. This problem usually means that your water supply is compromised, your water inlet hoses are faulty, or you opened the valves halfway. To fix the code, check your water inlet valve and hose for any faults.
In this article, you will understand the H20 error code, what causes the error to display on your display panel, how to clear the code, and fix its causes.
You will also get a sneak peek at other error codes and their meaning.
What Does the Error Code H2O Mean on My GE Dishwasher?
If your GE dishwasher displays an H20 error code, it indicates that the water flowing into the washer chamber is insufficient. It appears when there is no water flowing into the dishwasher.
This low water issue is often due to several underlying problems like a faulty water inlet valve, faulty inlet hose, improperly opened valve, or a dysfunctional water supply.
However, if the error code appears in the 1-hour wash cycle, you need to contact a professional to service the dishwasher.
If it appears in other wash cycles, a thorough inspection of your water source and the inlet valve will clear the error codes and help you identify the cause.
Furthermore, the H20 error code commonly appears:
- If you purchased the dishwasher recently,
- You are running the appliance for the first time,
- If you recently fixed your plumbing,
- You turned off your water supply recently.
The following are the underlying causes of the H20 error code in your GE dishwasher:
#1. Faulty Inlet Valve
The water inlet valve controls the amount of water that fills the dishwasher, and the timer controls it. It is faulty if it does not respond when you turn on the timer.
Open the lower access panel to locate the inlet valve to verify if the valve is functional.
Also, if the inlet valve does not have enough water pressure, your inlet valve might be the cause of the error code display.
#2. Faulty or Kinked Hose
If the inlet hose is faulty, it will not allow enough water to flow into the dishwasher chamber, hence the H20 error code.
The error code display could also be due to a bent or kinked hose. In this case, the hose will restrict water flow into the chamber due to its improper position.
#3. Improperly Opened Valve
If you recently turned off your inlet valve, you might want to check if you properly turned it on. You might have turned it on halfway, reducing the water flow pressure.
Apart from these common issues, your GE dishwasher might be displaying an H20 error code due to other issues like:
- A fault in the circuit board, or
- A problem with the main water supply.
Therefore, before trying to fix the error, ensure you have a good understanding of the source of the problem to avoid further unnecessary complications.
Apart from the H20 error code, there are other error codes you might need help deciphering on your display panel.
The table below shows some common GE error codes and what they indicate.
|GE error codes||Description|
|number + H||Indicates that your dishwasher is in a Delay Start mode.|
|999||This error indicates possible leakage.|
|C1, C2||Indicates that the pump-out cycle has exceeded two to seven minutes.|
|C3||Your dishwasher did not drain completely, or it will not drain.|
|C4||This error code indicates a clogged drain or a stuck float switch.|
|C5||The pump-out time during the drain cycle is too short.|
How Do I Fix the Error Code H2O on My GE Dishwasher?
To fix the error code in your GE dishwasher, locate the inlet valve near the dishwasher and check if it is completely ON. Check the inlet hose for any links or faults and fix them.
If the problem is not from the appliance, check your main water supply, it might be cut off or not completely turned on. Once you can detect the cause of the error code display, fixing it will not be a problem.
Here are some solutions to fix and clear the GE dishwasher H20 error:
#1. Replace Faulty Inlet Hose
The inlet hose connects the water inlet valve to the dishwasher chamber, allowing water inflow.
However, when the pipe develops a fault, it reduces the water pressure and activates the H20 error code.
To fix this issue, locate the inlet hose and inspect it for damages and faults. If the hose is faulty, replace the inlet hose.
#2. Straighten Kinked Hose
In this case, your hose might be in the wrong position, causing it to bend and restrict the water flow from the primary water source.
#3. Inspect the Water Valve
If the solutions above do not work, the water inlet valve might be the issue. However, to confirm the functionality of the inlet valve, you must inspect it.
Follow the steps below to examine your inlet valve:
- Disconnect your dishwasher from its power supply and turn off the water source.
- Check the lower left part of your dishwasher to locate your machine water inlet valve.
- You might need to open the lower access panel to access it.
- Inspect the inlet valve for cracks, wear, or any sign of damage. If you detect any in the inlet valve, replace the inlet valve.
Apart from the solutions above, you can try the tips below to clear the dishwasher error code:
- Ensure the washer is not tilting to one side. The tilt could lower the water level at one side of the washer’s chamber, triggering the error code.
- Choose a different cycle mode and reselect the previous wash cycle.
If the issue persists after trying the solutions above, schedule an appointment with a professional to service the washer.
How Do You Reset Error Codes on a GE Dishwasher?
You can reset error codes on GE dishwashers by disconnecting the power supply, entering service mode, or pressing the Start button.
The reset method you require depends mainly on the model of your appliance, the type of error code, and the location of its control panel.
Though resetting your washer is a good solution to clear error codes, it should be your last resort to fix any error code.
Here are the various ways to perform a reset on your dishwasher:
#1. Entering Service Mode
Most GE dishwasher models have a service mode that you can activate to reset the washer. The mode also helps you run tests to identify the cause of the error code in your dishwasher.
To activate service mode in your GE dishwasher:
- Press and hold the Select Cycle and Start buttons for about five seconds.
- Next, press and hold Select Cycle again for five seconds. This action will trigger the lock button.
- Then press the Start button again for about five seconds. This action will cause the Start button to flash repeatedly.
- Finally, repeat the first step to reset the dishwasher. This action will activate the control panel light and reset the dishwasher.
#2. Disconnecting the Power Supply
This method reset the dishwasher by draining off the electrical charges in the dishwasher.
To disconnect the power supply, unplug the dishwasher from the power supply. Wait for 30 seconds before turning it back on.
#3. Double Tap the Start Button
This reset method is suitable if your GE dishwasher is on but is not running. To reset the dishwasher, press the Start Button twice. This action will restart the cycle.
An H20 error code display on your control panel indicates that your dishwasher chamber is not getting enough water during a wash cycle.
Once you notice this error code, check your water supply, the water inlet valve, or the inlet hose for any issues. Once you detect any faults you cannot fix, contact an expert to service the washer.
