LG Dishwashers: Problems, Error Codes & Models

Use this page as the troubleshooting hub for LG dishwasher products. Start with what the product is actually doing, then move into the correct model page, diagnostic code, symptom guide, or repair service.

This page intentionally targets problems / troubleshooting / codes / models rather than competing with the commercial service page for the exact “repair” keyword.

Common LG Dishwashers Problems

Typical troubleshooting starts with one of these observable patterns:

• Will not drain
• Leaks or triggers leak protection
• Dishes remain dirty after a full cycle
• Will not fill normally
• Stops with an IE, OE, AE, LE, HE, or other code
• Drying or heating behavior changes

A symptom is a starting point, not a failed-part name. Compare the behavior with the model number and any code shown before moving into component-level diagnosis.

LG Dishwashers Error Codes

Read the code exactly as it appears and keep it inside the Dishwasher context. LG can reuse the same-looking code across different product families.

• AE — Leakage detected

/error-codes/lg-dishwasher-ae-error-code/

• FE — Overfill / excessive water level

/error-codes/lg-dishwasher-fe-error-code/

• IE — Water inlet/fill error

/error-codes/lg-dishwasher-ie-error-code/

• OE — Drain/outlet error

/error-codes/lg-dishwasher-oe-error-code/

• tE — Temperature sensor error

/error-codes/lg-dishwasher-te-error-code/

• HE — Heater/heating error

/error-codes/lg-dishwasher-he-error-code/

Troubleshooting Guides

• LG Dishwasher Not Draining
• LG Dishwasher Leaking
• LG Dishwasher Not Cleaning

These guides begin with the symptom and explain when safe owner checks should stop.

Repair Services

• LG Dishwasher Repair

Commercial service pages own the “LG ___ repair” intent. This product hub remains the information/navigation parent for troubleshooting, codes, and models.

How to Narrow a Problem Safely

1. Confirm the exact product type.
2. Record the full model number when accessible.
3. Copy the display code exactly.
4. Note when the symptom begins and what changes it.
5. Complete only normal owner checks relevant to the product.
6. Stop before live electrical testing, sealed-system work, gas-system work, pressure testing, or deeper disassembly not covered by owner instructions.

Why Product-Family Context Matters

LG uses different control systems and diagnostic conventions across refrigerators, laundry products, dishwashers, cooking appliances, air products, heat pumps, commercial VRF systems, and other platforms. A code or symptom should therefore stay connected to the correct product family rather than being treated as a universal LG definition.

FAQ

Where should I start if I only know the symptom?

Start with the most specific behavior you can verify—such as not cooling, not draining, leaking, not heating, unusual noise, or a repeat display message—and then choose the matching guide or model page.

Do all LG Dishwashers use the same error codes?

No. Codes can vary by platform, model generation, features, and region. Use the correct family context and model documentation when the diagnosis becomes specific.

Can I request service without a model number?

Yes. The product type and symptom are enough to begin a request. The full model number is still useful for model-specific troubleshooting and service planning.

Is this an official LG support page?

No. This is independent repair and troubleshooting content organized using LG product and model references.

Need Repair Instead of More Troubleshooting?

If the same symptom keeps returning, move from the troubleshooting hub to the matching repair service.
