Oe Error Meaning
The LG dishwasher displays the OE error code when it detects a drainage problem. This code means the water inside the dishwasher is not draining properly. The appliance stops the cycle to prevent water from flooding your kitchen.
Understanding what causes the OE error helps fix the issue quickly. It also prevents damage to the dishwasher and your home. Many times, the problem involves simple blockages or kinks in the drain system.
What Does The Oe Error Code Mean?
The OE error code stands for “Overflow Error.” It shows the dishwasher cannot drain water as expected. This error appears during or after the wash cycle. It signals that water is stuck inside the tub or drain hose.
Common Causes Of The Oe Error
Several factors can cause the OE error. The most common is a clogged filter filled with food debris. Another cause is a bent or pinched drain hose. Sometimes, a garbage disposal’s knockout plug blocks the drain. The air gap or disposal waste spigot may also have clogs.
How To Identify Drainage Issues
Check the dishwasher filter and clean it regularly. Inspect the drain hose for kinks or blockages. Ensure the garbage disposal knockout plug is removed after installation. Remove and clean the air gap if your sink has one. Also, clear any food residue from the disposal waste spigot.

Common Causes
The LG dishwasher error code OE signals a drainage issue. Understanding common causes helps you fix it faster. Drainage problems stop the dishwasher from emptying water properly. This can lead to error codes and poor washing results. Several parts may block water flow or cause drainage failure. Check these areas to find the root cause.
Clogged Filter
The filter catches food and debris during washing. Over time, it can get blocked and stop water flow. A clogged filter causes water to drain slowly or not at all. Remove the filter from the bottom of the dishwasher. Clean it with warm water and a soft brush. Regular cleaning prevents drainage errors and keeps your dishwasher working well.
Blocked Drain Hose
The drain hose carries dirty water out of the dishwasher. It can get kinked, bent, or clogged by debris. Any blockage stops water from draining properly. Check the hose under your sink for bends or clogs. Straighten any kinks and clear any blockages. This simple step often solves the OE error quickly.
Garbage Disposal Knockout Plug
If your dishwasher connects to a new garbage disposal, check the knockout plug. This plastic plug blocks the dishwasher drain until removed. Forgetting to remove it stops water drainage. Locate the plug on the disposal unit and remove it carefully. Removing the plug allows water to flow from the dishwasher to the disposal.
Dirty Air Gap
The air gap prevents dirty water from flowing back into the dishwasher. It sits on the sink or countertop. Debris can build up inside the air gap, causing a blockage. Remove the air gap cover and clean it with a brush and water. A clean air gap ensures proper drainage and prevents error codes.
Clogged Disposal Waste Spigot
The disposal waste spigot connects the dishwasher drain hose to the garbage disposal. Food waste can clog this spigot and block water flow. Inspect the spigot and clear any food debris. Cleaning this area helps water drain smoothly from the dishwasher.
Quick Fixes
Quick fixes can solve the LG dishwasher error code OE fast. This error means the dishwasher has trouble draining water. Many simple steps can clear blockages and get the water flowing again. Trying these fixes might save a service call and get your dishwasher working today.
Clean The Filter
Start by locating the dishwasher filter at the bottom. Remove it carefully and rinse with warm water. Use a soft brush to scrub away food bits and debris. A clean filter helps water drain smoothly and stops clogs.
Check And Clear Drain Hose
Look under the sink for the dishwasher drain hose. Make sure it is not bent or pinched. Detach the hose and run water through it to clear blockages. A clear hose ensures water flows out easily.
Remove Knockout Plug
New garbage disposals often have a knockout plug blocking the dishwasher drain. Check if the plug is still inside the disposal inlet. Remove it by knocking it out carefully. This allows water to drain from the dishwasher into the disposal.
Clean Air Gap
Find the air gap on your sink, a small cylindrical cap near the faucet. Remove the cap and clean inside to remove debris. A clean air gap helps prevent water backup in the dishwasher.
Clear Disposal Spigot
Check where the drain hose connects to the garbage disposal. Food waste can clog this spigot. Use a brush or a small tool to clean out any gunk. Clearing the spigot helps water drain freely from the dishwasher.
Resetting The Dishwasher
Resetting the dishwasher is a simple yet effective step to clear error codes like the LG dishwasher OE error. This process helps restart the system and can fix minor glitches. It often solves issues related to drainage and electronic faults.
Resetting does not require special tools or technical skills. You can perform it quickly using basic methods. Two common ways include power cycling and manual drain override. Both methods help the dishwasher refresh its functions and clear error messages.
Power Cycle Method
First, turn off the dishwasher completely. Unplug it from the power source or switch off the circuit breaker. Wait for about five minutes to let the system reset fully. After the wait, plug the dishwasher back in or turn the breaker on. Turn on the dishwasher and check if the OE error has cleared. This method often resets the dishwasher’s control board and resolves minor electrical issues.
Manual Drain Override
If power cycling does not work, try the manual drain override. Open the dishwasher door and press the “Cancel” or “Drain” button if available. This forces the dishwasher to drain water manually, clearing any stuck water causing the OE error. You may hear the pump running during this process. Wait until the water drains completely. Close the door and restart the dishwasher to see if the error disappears. This method helps if water is trapped inside the dishwasher.
Drain Pump Issues
The drain pump plays a key role in removing water from your LG dishwasher. Problems with this pump often cause the OE error code. The dishwasher cannot drain properly if the pump is faulty or blocked. This leads to incomplete wash cycles and standing water inside the unit.
Understanding the signs of a faulty pump can help you fix the issue quickly. Testing the pump ensures it works correctly. If needed, replacing the drain pump restores proper drainage and dishwasher function.
Signs Of A Faulty Pump
Water remains in the dishwasher after the cycle ends. You hear strange noises during draining. The dishwasher stops mid-cycle showing the OE error code. These are common signs of a bad drain pump. The pump may also fail to start or run weakly.
Testing The Pump
First, unplug the dishwasher for safety. Remove the lower panel to access the drain pump. Use a multimeter to check the pump’s electrical resistance. A reading of zero or infinity means the pump is defective. Spin the pump impeller by hand; it should move freely without resistance.
Replacing The Drain Pump
Turn off the water supply and unplug the dishwasher. Disconnect the drain hose and electrical connectors from the pump. Remove the mounting screws holding the pump in place. Install the new pump by reversing these steps. Secure all connections tightly to prevent leaks. Test the dishwasher to confirm the OE error is cleared.

Advanced Problems
Advanced problems with the LG dishwasher error code OE often point to deeper issues. These faults affect key components responsible for proper drainage and overall function. Understanding these problems helps in accurate diagnosis and repair. Below are common advanced issues linked to the OE code.
Drain Motor Fault
The drain motor pushes water out of the dishwasher. If it fails, water cannot drain properly. Signs include loud noises or no drainage at all. The motor may be jammed or burnt out. Testing the motor with a multimeter can confirm faults. Replacing a faulty motor restores proper drainage.
Control Board Issues
The control board manages the dishwasher’s operations. A damaged board can misread sensors or stop the drain pump. This causes the OE error to appear repeatedly. Moisture or power surges often damage the control board. Inspecting the board for burns or cracks helps identify problems. Swapping the control board is necessary if faults exist.
Pressure Sensor Failures
The pressure sensor detects water levels inside the dishwasher. Failure leads to wrong water level signals. This confuses the control board and stops drainage. A faulty sensor may show erratic water levels or cause overflow. Testing the sensor with a multimeter can reveal problems. Replacing the pressure sensor fixes drainage errors linked to OE.
When To Call A Technician
Knowing when to call a technician for an LG dishwasher error code OE is important. This code signals a drainage issue, which can sometimes be fixed at home. Simple tasks like cleaning the filter or checking the drain hose often solve the problem.
Still, some situations need a professional’s help. Calling a technician ensures the problem gets fixed safely and correctly. This section explains when it is best to seek expert service for your dishwasher.
Persistent Error Code After Basic Checks
If the OE error stays after cleaning filters and hoses, call a technician. The problem might be inside the drain pump or wiring. A technician can diagnose and fix these complex issues.
Water Not Draining Or Leaking
Water pooling inside or leaking outside the dishwasher needs expert attention. Technicians can find hidden blockages or damaged parts causing leaks. Delaying repair may cause water damage to your kitchen.
Unusual Noises During Drain Cycle
Loud or strange sounds during drainage often point to mechanical faults. A professional can inspect the pump and motor for worn or broken components. Avoid using the dishwasher until it is checked.
Multiple Error Codes Displayed
When more than one error code shows, the issue may be electrical or control board related. A qualified technician can run tests and repair or replace faulty electronics safely.
After Failed Reset Attempts
Resetting the dishwasher by unplugging it sometimes clears the OE code. If resetting fails repeatedly, a technician should examine the appliance. They can identify hidden faults that cause persistent errors.
