Browse by Common Appliance Problem
You may not always see a clear error code. Some appliances display flashing lights, warning symbols, beeping patterns, or unusual behaviour instead.
Choose a problem to find relevant troubleshooting guides:
- Appliance will not start
- Appliance keeps stopping
- Water is not draining
- Water is not entering
- Appliance is not heating
- Appliance is not cooling
- Door will not lock
- Lights are flashing
- Appliance keeps beeping
- Appliance is making unusual noise
- Circuit breaker keeps tripping
- Error returns after reset
Include the appliance brand and model number when searching for a symptom.
For example:
- LG washer not draining
- Bosch dishwasher beeping three times
- Samsung refrigerator not cooling
- Whirlpool dryer not heating
- Daikin air conditioner flashing green light
Why Appliance Type Matters
Manufacturers often reuse similar error-code formats across different appliances.
For example, an E1 code on a washing machine may relate to water supply, while an E1 code on an air conditioner may relate to a temperature sensor or communication problem.
Always confirm:
- Appliance type
- Brand
- Model number
- Exact error code
- Country or region
Model numbers and code meanings may differ between the United States, United Kingdom, Canada, Australia, New Zealand, and Ireland.
How to Find Your Appliance Model Number
The model number is usually printed on a product label or rating plate.
Common locations include:
Washing machines and dryers
Check inside the door, around the door frame, behind the appliance, or near the detergent drawer.
Dishwashers
Look along the inside edge of the door or around the door frame.
Refrigerators
Check inside the fresh-food compartment, behind a drawer, or on an interior side wall.
Air conditioners
Look on the side of the indoor unit, outdoor unit, rear panel, or product label.
Ovens and microwaves
Check around the door frame, inside the door, behind the appliance, or inside a storage drawer.
Boilers and furnaces
Look on the front panel, side casing, control compartment, or installation label.
The model number is different from the serial number. The model identifies the product design, while the serial number usually identifies one individual unit.
How to Get the Best Search Result
Use as much information as possible.
A strong search includes:
Brand + Appliance + Error Code + Model
Examples:
- LG washer OE error
- Samsung dryer HC error
- Bosch dishwasher E15
- Whirlpool refrigerator PO code
- Daikin air conditioner U4 error
- Worcester boiler EA fault
If the first search does not show the right result:
- Add the appliance type.
- Add the model number.
- Remove spaces or dashes from the code.
- Check whether zero and the letter O have been confused.
- Search for the flashing-light pattern.
- Search for the visible symptom instead of the code.

- What to do if the basic fix fails
- Parts that may be involved
- Affected models

Important Safety Notice
Stop using the appliance if you notice:
- Smoke
- Sparks
- Burning smells
- Gas smells
- Water near electrical connections
- Severe overheating
- Damaged wiring
- Repeated circuit-breaker trips
- Refrigerant leakage
- Loud grinding or metal contact
Disconnect the appliance from power only when it is safe to do so.
Repairs involving electricity, gas, refrigerants, internal wiring, sealed systems, or major disassembly should be handled by a qualified professional.
Frequently Asked Questions
Which appliance category should I choose?
Choose the exact appliance showing the error. If you have a washer-dryer combination, start with the washer-dryer or washing-machine section and include the full model number.
Why does the same error code show different meanings?
Error codes are created by individual manufacturers. A code may have one meaning on a washer and another meaning on a refrigerator or air conditioner.
Can I search by symptom instead of error code?
Yes. Search using the appliance, brand, and visible problem, such as “Bosch dishwasher not draining” or “LG dryer not heating.”
Should I include the model number?
Yes. The model number helps identify the correct instructions, parts, controls, and regional version of the appliance.
Are all troubleshooting steps safe for homeowners?
No. Basic checks may be suitable for homeowners, but electrical, gas, refrigerant, internal wiring, and major component repairs should be performed by qualified professionals.
Is Error Code Vault connected with appliance manufacturers?
No. Error Code Vault is an independent informational website. Brand names, product names, model numbers, and trademarks belong to their respective owners.
