GE Dishwasher H20 Error: 4 Easy Fixes To Try
Seeing an H20 error in your dishwasher? Don’t worry, it doesn’t mean your washer’s doing the mechanical equivalent of drowning – it’s simply low on the H20 supply.
The GE Dishwasher H2O error is common and often happens due to loose water connections or water supply issues. Sometimes, it’s a tricky pressure sensor causing trouble. Fixes usually involve tightening connections, checking the water supply, or giving that sensor a good cleaning.
Keep reading the post to learn more about the reasons and how to get on about fixing them. Let’s get started.
What Causes The H2O Error In GE Dishwashers?
The error comes up due to various water related errors, hence the “H20” code. Let me go through all the reasons.
Cause 1: Loose Water Supply Line Connection
The H20 error on GE dishwashers might pop up if the water supply line isn’t snugly connected during installation or to the hot water valve.
If there’s a loose connection, the dishwasher won’t get the water it needs, triggering the error.
Cause 2: Turned Off Water Supply
When the water supply line is unintentionally turned off, the dishwasher can’t access water, causing the H20 error.
Cause 3: First-Time Washer Operation
Running the dishwasher for the first time involves an initial setup.
If the water supply isn’t steady or there are hitches during this crucial startup, the H20 error may appear as the dishwasher struggles to establish proper water flow.
Cause 4: Recent House Plumbing Completion
If the house plumbing has just been finished, there might be air pockets or debris causing water supply disruptions.
These issues can lead to the H20 error as the dishwasher tries to navigate a newly configured plumbing system.
Cause 5: Wonky Pressure Sensor
Down at the bottom of the dishwasher, there’s a pressure sensor.
If it’s acting up or not sensing the water pressure correctly, it can confuse the dishwasher, triggering the H20 error.
GE Dishwasher H20 Error Fix
Here’s a rundown of some quick fixes – one of them will usually do the job. You’re very unlikely to end up needing to call in servicing.
Fix 1: Check for Kinked Inlet Water Hose
- Trace the inlet water hose from the dishwasher to its connection point.
- Straighten any kinks or bends in the hose.
- Reconnect the hose securely to the dishwasher.
Fix 2: Make Sure The Hot Water Valve Under the Sink Is Functioning
- Turn off the hot water valve under the sink.
- Place a container under the water hose connection point to catch any residual water.
- Unscrew the water hose connected to the hot water valve.
- Turn the hot water valve clockwise to open it fully.
- Reconnect the water hose securely and turn on the hot water valve.
Fix 3: Ensure Proper Leveling
Correct leveling prevents water from pooling in the wrong areas and sometimes sets off the sensor.
A leveled dishwasher ensures even water distribution during the cycle. Here’s what to do:
- Open the dishwasher door and remove the lower rack.
- Use a bubble level on the floor of the dishwasher.
- Adjust the leveling legs at the front and rear of the dishwasher to achieve proper leveling.
- Reinstall the lower rack and close the dishwasher door.
Fix 4: Check The Pressure Sensor
- Ensure that the dishwasher is turned off and unplugged from the power source to ensure safety.
- Fully open the dishwasher door.
- If there are any racks or utensil baskets inside, remove them for better access.
- Find the sump- the lowest part of the dishwasher where water collects during the wash cycle. It’s usually located at the bottom center of the dishwasher.
- Search for a small electronic device or sensor mounted near or within the sump area. It may be attached to the side or bottom of the dishwasher.
- Clean the sensor gently using a soft cloth to get rid of any fat and oil buildup.
- If that doesn’t help, follow manual instructions for replacement.
FAQs
How do I test my GE dishwasher water inlet valve?
Locate the valve behind the kickplate, usually in a dishwasher corner. Disconnect power, set your multimeter to Rx1, and place probes on valve terminals. If the reading is close to zero, your valve is good.
Where is the flood float on my GE dishwasher?
Look at the dishwasher bottom to spot the flood float. Remove Ultra Fine and Fine filters to access it. The float rises with water, triggering the float switch.
