Oe Error Meaning
The OE error on an LG dishwasher means there is a drainage problem. This error stops the dishwasher from completing its cycle. Water fails to drain properly, causing the machine to pause and show the OE code. Understanding this error helps you fix it quickly and avoid damage.
Drainage is key for dishwashers to work well. If water stays inside, dishes will not get clean. The OE error alerts you to check the drainage system and clear any blockages or faults.
Drainage Problem Signal
The OE error signals that the dishwasher cannot drain water. This could be because the drain hose is blocked or bent. It can also mean the filter is clogged with food debris. The drain pump might not be working properly either. When water cannot leave the dishwasher, the OE error appears on the display.
Common Causes
- Clogged Filter: Food particles block water flow in the filter.
- Blocked Drain Hose: Kinks or dirt stop water from draining out.
- Garbage Disposal Knockout Plug: If newly installed, this plug may still be inside the drain connection.
- Dirty Air Gap: Debris can build up in the air gap on your sink.
- Faulty Drain Pump: The pump may be broken or clogged and not push water out.
Filter Cleaning
Cleaning the filter is a key step to fix the LG dishwasher OE error. The filter catches food bits and debris. Over time, it can get clogged and block water flow. This causes drainage problems and triggers the OE error code. Regular cleaning keeps your dishwasher running smoothly and prevents errors.
Removing The Filter
Open the dishwasher door fully. Locate the filter at the bottom of the tub. Turn the filter counterclockwise to unlock it. Pull the filter straight up and out. Handle it carefully to avoid damaging the mesh. Keep the filter in a safe place for cleaning.
Washing And Scrubbing
Rinse the filter under warm running water. Use a soft brush to scrub away stuck food and grease. Avoid harsh brushes that can tear the mesh. Clean both the fine and coarse parts of the filter. After scrubbing, rinse again to remove loosened debris. Dry the filter with a clean cloth before placing it back.
Drain Hose Check
Checking the drain hose is a key step in fixing the LG dishwasher OE error. This error signals a problem with draining water properly. The hose can sometimes get blocked or bent, stopping water flow. Regular inspection helps spot these issues early. Fixing hose problems often clears the error and restores dishwasher function.
Locating The Hose
The drain hose usually runs from the dishwasher to the sink drain or garbage disposal. Find it under the kitchen sink or behind the dishwasher. It is a flexible tube, often made of plastic or rubber. Make sure the hose is connected firmly at both ends. Loose connections can cause leaks or drainage errors.
Identifying Kinks And Blockages
Look closely at the hose for sharp bends or twists. Kinks stop water from flowing and can cause the OE error. Straighten any bends you find. Check inside the hose for blockages like food scraps or debris. Use a long brush or run water through it to clear clogs. A clean and smooth hose helps the dishwasher drain well.
Garbage Disposal Inspection
Inspecting the garbage disposal is key to solving the LG dishwasher OE error. This error shows a drainage issue, often linked to the garbage disposal setup. A thorough check can clear blockages and ensure smooth water flow. Start with simple steps for better results.
Knockout Plug Removal
The knockout plug blocks the dishwasher drain in a new garbage disposal. It must be removed for proper drainage. Locate the plug inside the disposal inlet. Use a screwdriver or hammer to knock it out carefully. After removal, flush the disposal with water to clear debris.
Clearing Waste Spigot
The waste spigot connects the dishwasher drain hose to the garbage disposal. Food particles often clog this area. Detach the drain hose and inspect the spigot. Use a small brush or cloth to clean inside. Make sure no residue blocks the water flow for better drainage.
Air Gap Maintenance
Maintaining the air gap is essential to fix the LG dishwasher OE error. The air gap prevents dirty water from flowing back into the dishwasher. Over time, debris can block the air gap. This blockage stops water from draining properly and causes the OE error.
Regular cleaning keeps the air gap clear. It helps your dishwasher drain smoothly. The cleaning process is simple and quick. Follow these steps to maintain the air gap and avoid drainage problems.
Removing The Cap
Start by locating the air gap on your sink or countertop. It looks like a small cylinder with a cap on top. Grasp the cap firmly and twist it off or lift it straight up, depending on your model. Set the cap aside carefully. Removing the cap gives you access to the inside of the air gap.
Cleaning Debris
Use a small brush or cloth to clean inside the air gap. Remove any visible dirt, food particles, or buildup. Run water through the air gap to flush out hidden debris. Make sure the water flows freely without blockage. After cleaning, replace the cap securely. This simple step can clear drainage issues and stop the OE error code.
Resetting The Dishwasher
Resetting the dishwasher can help clear error codes like the LG dishwasher OE error. This process restarts the machine’s control board. It may fix minor glitches affecting the drainage system. Resetting is a simple step before calling for repair. Follow the power cycle steps carefully to avoid damage.
Power Cycle Steps
First, turn off the dishwasher using the power button. Then, unplug the dishwasher from the power outlet. Wait for at least 5 minutes to let the system reset. After the wait, plug the dishwasher back in. Press the power button to turn it on. Check if the OE error disappears and the dishwasher drains properly.
When To Try Reset
Try resetting the dishwasher after cleaning the filter and drain hose. Also, reset if the dishwasher shows the OE error repeatedly. Avoid resetting if the dishwasher makes loud noises or leaks water. Reset only after ensuring no physical blockages exist. If the error returns often, professional help may be needed.
Drain Pump Troubleshooting
Drain pump troubleshooting helps fix the LG dishwasher OE error quickly. This error means the dishwasher cannot drain water properly. The drain pump moves water out of the dishwasher. If the pump has a problem, the dishwasher shows the OE error. Simple checks can find out if the pump works well or not.
Start by listening to the pump noise and forcing the drain mode. These steps show if the pump runs and drains water as it should. If the pump is silent or stuck, it needs cleaning or replacement. Let’s explore these methods in detail.
Listening For Pump Noise
Turn on the dishwasher and start a cycle. Listen carefully near the bottom for a humming or buzzing sound. This noise means the drain pump is running. No sound may mean the pump is broken or blocked.
If you hear strange noises like grinding or rattling, debris might be inside the pump. Cleaning or removing the blockage can help. If the pump is silent, check the power supply or wiring to the pump. A faulty pump motor may need replacement.
Forcing Drain Mode
Forcing drain mode helps test if the pump can drain water. Open the dishwasher door slightly and press the “Start” button for three seconds. This action activates the drain pump directly.
Water should start draining quickly. If water does not drain, check the drain hose for clogs or kinks. Also, inspect the air gap and garbage disposal connection for blockages. If everything is clear and the water still won’t drain, the drain pump may be faulty.
Repeat forcing the drain mode a few times to confirm the problem. If the dishwasher still shows the OE error, call a professional technician for pump repair or replacement.
Pump Replacement Indicators
The LG dishwasher OE error often points to drainage issues. One common cause is a faulty pump. Recognizing pump replacement signs helps avoid bigger problems. Early detection saves time and repair costs. Watch for specific symptoms that show pump failure.
Humming Without Draining
A humming sound without water draining signals a possible pump issue. The motor tries to run but can’t push water out. This happens when the pump impeller is stuck or damaged. Debris or small objects can block the pump. The motor hums but the dishwasher stays full of water. This sign means the pump needs checking or replacement.
Post-clearance Error Persistence
After clearing clogs and cleaning filters, the OE error remains. This persistence suggests the pump is failing internally. Even if hoses and filters are clean, the pump might not work correctly. Electrical faults or worn parts inside the pump cause this issue. Replacing the pump often stops the error from coming back.
Advanced Issues
Advanced issues causing the LG dishwasher OE error often involve key components. These problems go beyond simple blockages. Understanding these issues helps in accurate troubleshooting and repair.
Drain Motor Problems
The drain motor pushes water out of the dishwasher. If it fails, water stays inside. This triggers the OE error code. Motors can wear out or get stuck due to debris. Testing the motor with a multimeter shows if it works. Replacing a bad motor restores proper drainage.
Control Board Faults
The control board manages dishwasher functions. Faulty boards may not signal the drain motor to run. This causes the OE error. Signs include no response during drain cycles. Moisture or electrical damage often causes board faults. Resetting or replacing the control board fixes this problem.
Pressure Sensor Errors
Pressure sensors detect water levels inside the dishwasher. Malfunctioning sensors send wrong signals. This confuses the system and stops drainage. Sensors can fail due to dirt or wiring issues. Cleaning or replacing the pressure sensor can clear the OE error code.

Signs Of A Persistent Oe Error
The OE error repeats after you clean the filter and drain hose. The dishwasher fails to drain water fully. Strange noises come from the drain pump area. These signs suggest a deeper problem. A professional can diagnose and fix these issues safely.
Complex Drain Pump Issues
The drain pump may be clogged or broken. Cleaning it is tricky and needs special tools. If the pump does not work after cleaning, it might need replacement. A technician has the right skills and parts for this job.
Blocked Air Gap Or Disposal Spigot
Sometimes, the air gap or garbage disposal spigot blocks drainage. These parts are hard to access and clean properly. Professionals use proper tools to clear these blockages. They ensure the dishwasher drains smoothly again.
