Error codes
| Code | Meaning | Checks |
|---|---|---|
| OE | The washer drains slowly or not at all. | 3 causes |
| UE | The load is unbalanced: clothes have gathered on one side of the tub, often because the load is too small. | 3 causes |
| IE | No water is coming in, or the water pressure is low. | 4 causes |
| dE1, dE2 | The door is not secured, so the tub does not rotate. | Checks |
| LE | The tub does not rotate, usually because the washer is overloaded and the motor has overheated. | Checks |
| Sud | Too many suds. The washer adds a suds-reducing routine of about two hours, and stops spinning if suds appear during spin, to prevent leaks. | Checks |
| tCL | Not a fault. The tub needs cleaning; the reminder generally appears every 1 to 2 months depending on use. | Checks |
| PF | A power failure occurred during the cycle. | Checks |
| tE, FE, PE | tE is a control error, FE means the water supply does not stop, and PE means the water level sensor is not working. LG gives no owner fix. | Checks |
| CL | Not a fault. Child Lock is on: the buttons are locked, but the door is not. The lock stays on after the washer shuts off, and only the Power button works. | Checks |

Problems
- Door does not open when the cycle pauses or finishes2 causes in the manual. First: the tub is too hot. A safety lock keeps the door shut to prevent burns.
- Washer does not turn on2 causes in the manual. First: the plug is not in properly.
- Washer vibrates, thumps or is noisy4 causes in the manual. First: the shipping bolts are still fitted.
- Washer smells musty or moldy3 causes in the manual. First: detergent residue and dirt build up in the tub, on the door gasket or in the drain pump filter.
- Water leaks around the washer2 causes in the manual. First: A faucet or water line leaks or is loosely connected.
- Banging noise when the washer fills2 causes in the manual. First: plumbing in the home moves or flexes when the water valves in the washer shut off. This is not caused by a defect in the washer.
Cycle takes longer than usual
Normal. The washer adjusts the cycle time to the load size, water pressure, water temperature and other conditions. Excess suds add about two hours. Source: Troubleshooting: Before Calling for Service; Checking Error Messages, pp. 35, 37
Clicking, hissing or buzzing sounds
Normal: clicks come from the door lock, hissing from water spraying in the tub, and buzzing or gushing from the drain pump. Source: Troubleshooting: Before Calling for Service, p. 36
