What causes LG Dishwasher OE Code?
When a dishwasher displays an OE error code, it indicates that the unit has detected a drain issue. There are several causes of this error code. They include:
1. Washing Machine Installation Issue
A dishwasher may display an OE error code if not installed properly. If the drain hose is not installed correctly, it can result in an OE error code.
2. Kinked Drain Hose
A kinked drain hose is one of the most common causes of an OE error code in LG dishwashers.
If the drain hose gets bent or twisted, it can restrict the water flow out of the dishwasher and cause an OE error code.
3. Drain Issue
A dishwasher may display an OE error code if there is a problem with the drain. The drain may be clogged with food debris or other objects, or there may be a problem with the drain pump.
4. Drain Filter
If the drain filter is clogged with food debris, it can restrict the water flow out of the dishwasher and cause an OE error code.
5. Food Debris
Food debris can accumulate in the dishwasher and cause an OE error code. Removing large food debris from the dishwasher before running a cycle is essential.
6. Malfunctioning Components
Malfunctioning components like the drain pump or valve can cause an OE error code. If any of these components fail, they will need to be replaced.
It is essential to troubleshoot the above issues to resolve the OE error code.
How to Fix LG Dishwasher OE Code
An OE error code on an LG dishwasher’s display shows that the unit has detected a drain issue, often resulting from food clogs or an installation issue. Here are some steps to follow to fix LG dishwasher OE error codes:
1. Inspect for Food Debris
If you find any food debris in your dishwasher’s tub, remove larger food debris and items that may not wash out. Secondly, Perform maintenance activities, which include cleaning the filters, cleaning the spray arms, and running a maintenance cycle.
After cleaning the dishwasher, try running a standard or heavy-duty cycle with no dishes or detergent. This will flush the unit as well as test the drain function.
2. Wash the Filter
Cleaning the filter is essential to ensuring that your dishwasher runs smoothly. Begin by removing the lowest rack of your dishwasher to clean (or wash) the filters.
The filter can be found below the long spray arms under the rack.
3. Inspect the Drain Hose
If the drain hose is kinked, the dishwasher will not drain properly. To avoid kinks, inspect and adjust the drain hose.
Look for a ridged or corrugated hose under the sink. It will be white, translucent, or gray. Check to see if anything has been pushed against or on top of the hose, causing it to become pinched or kinked.
Run a test cycle after straightening the hose.
4. Inspect the Air Gap
The OE error code is triggered when the dishwasher is not draining properly. Check the drain air gap or in-sink disposal for debris and clogs.
Check the knockout plug to see if the dishwasher has a new garbage disposal installed.
5. Force the Drain
Check the control panel for the CANCEL & DRAIN option to perform a drain only. This is activated by pressing and holding two buttons, e.g., DELICATE + DUAL CONTROL. The two buttons may vary depending on your model.
If your model does not have a CANCEL & DRAIN option, start a cycle, let it run for 45 seconds, then power the unit off. The first 45 seconds of any cycle is drain only.
6. Check the Wash Cycle
Sometimes, the wash cycle is too short, resulting in the dishwasher not fully draining. Check the wash cycle to ensure that it’s running for the proper length of time.
7. Check the Drain Pump Filter
The drain pump filter can be found at the bottom of the dishwasher, and it can become clogged with debris. To clean the drain pump filter, unplug the dishwasher and remove the lower front panel to access the filter.
Turn the filter counter-clockwise to remove and clean it with warm water and a soft brush. Re-install the filter and the front panel and plug in the dishwasher.
8. Check the Drain Pump and Motor
If the drain pump filter is clean, but the dishwasher still won’t drain, check the drain pump and motor for any damage or malfunction.
If the pump or motor is damaged, it may need to be replaced.
9. Check the Control Panel
If all of the above steps fail to fix the OE error code, check the control panel for any error codes or malfunctions. Refer to the dishwasher manual for troubleshooting tips specific to your model.
If the control panel is malfunctioning, it may need to be replaced.
10. Request a Repair
If you try all the options above and the OE error code displays again, the unit will require a repair service.
How To Prevent LG Dishwasher OE Error Code
Following some simple maintenance and usage guidelines is vital to prevent LG Dishwasher OE Error Codes from occurring.
1. Proper Loading
Ensure that dishes are correctly loaded and not blocking the dishwasher’s spray arms. Overloading the dishwasher can lead to incomplete cleaning, resulting in food debris clogging the dishwasher’s filters and drain.
2. Pre-Rinse Dishes
Before loading dishes into the dishwasher, it is recommended to rinse off any large food particles. This will help prevent food debris from clogging the dishwasher’s filters and drain.
3. Regular Cleaning

5. Run Hot Water
Before starting a wash cycle, run the hot water at the kitchen sink until it is hot. This will help ensure that the dishwasher starts with hot water and will help dissolve detergent and food debris.
6. Use the Appropriate Wash Cycle
Use the appropriate wash cycle for the type of load being washed. For example, use a heavy-duty wash cycle if the load contains heavily soiled dishes.
7. Check Drain Hose and Connections
Check the dishwasher’s drain hose and connections for kinks or blockages. Straighten out any kinks and ensure that the connections are secure.
By following these simple maintenance and usage guidelines, you can help prevent LG Dishwasher OE Error Codes and ensure that your dishwasher operates at peak performance.
