LG Dishwasher Error OE Manual

The LG Dishwasher Error OE indicates a drainage issue where the dishwasher cannot properly drain water. This error typically occurs due to clogged filters, blocked drain hoses, or problems with the drain pump. Below are comprehensive sections covering error identification, causes, troubleshooting steps, preventive maintenance, and professional service information.

Error OE Overview

Error OE appears on the display panel when the dishwasher detects a drainage problem. The system monitors water flow during drain cycles and triggers this error if water remains in the tub after attempted drainage.

Common Causes

Multiple factors can trigger the OE error code in LG dishwashers.

1. Clogged drain filter or food debris
2. Kinked or blocked drain hose
3. Obstructed air gap or garbage disposal connection
4. Faulty drain pump or motor
5. Drain hose installation issues
6. High loop not properly installed

WARNING! Always disconnect power before inspecting drainage components to prevent electrical shock.

Troubleshooting Steps

Follow these steps systematically to resolve OE error.

1. Cancel current cycle: Press and hold START/RESET for 3 seconds.
2. Check drain filter: Remove lower rack and clean filter assembly.
3. Inspect drain hose: Ensure no kinks or obstructions.
4. Verify installation: Confirm proper high loop and connection to disposal/sink.
5. Test drain pump: Listen for humming sound during drain cycle.
6. Reset dishwasher: Unplug for 5 minutes or turn off circuit breaker.

CAUTION! Do not operate dishwasher with standing water as it may cause overflow or damage.

Drain System Components

• Drain Filter: Captures food particles; requires regular cleaning
• Drain Hose: Flexible tubing connecting to sink drain or disposal
• Drain Pump: Electric pump that moves water out of dishwasher
• Air Gap: Prevents backflow into dishwasher (if installed)
• High Loop: Prevents sink water from siphoning back
• Check Valve: Prevents water backflow in drain system

Cleaning Procedures

Proper cleaning prevents OE errors and maintains optimal performance.

Filter Cleaning: Twist counterclockwise to remove, rinse under water, reassemble securely.

Drain Hose Inspection: Disconnect from sink/disposal, check for obstructions, flush with water.

Pump Area Cleaning: Remove bottom cover, clear debris around impeller area.

Monthly Maintenance: Run empty cycle with vinegar to clean internal components.

Reset Instructions

Reset procedures can clear temporary OE errors.

1. Press and hold START/RESET button for 5 seconds
2. Unplug dishwasher from power for 10 minutes
3. Turn off circuit breaker for 5 minutes then restore power
4. For hard reset: Hold HEAT DRY and START simultaneously for 10 seconds

Note: Resets may clear error but won't fix physical obstructions.

Preventive Maintenance

Regular maintenance reduces OE error frequency.

Always follow safety guidelines when troubleshooting.

Electrical Safety: Disconnect power before accessing internal components.

Water Safety: Have towels ready for potential water spills.

Component Handling: Avoid forcing parts; refer to manual for proper removal.
