LG front-load washer error codes:
Reference Model: This chart covers codes for most LG front-load washers including the LG Tromm WM2277HW error codes.
These error code explanations can help you diagnose a problem with your LG front-load washer.
LG washer error codes appear on the control panel display when the control board detects a problem. Look up the code being signaled and follow the troubleshooting steps to fix the problem.
| Code | Meaning | Possible Cause | Possible Parts |
| IE | Inlet water supply error | The initial expected water level isn't reached in 8 minutes or the final preset water level isn't reached in 25 minutes. Check the water supply faucets behind the washer to make sure they are fully open. Check the fill hoses for kinks or freezing (in winter). Check the inlet water valves. If the valves are defective, replace the inlet water valve assembly. If the water valves are okay, replace the main electronic control board | Inlet water valve assembly, Main electronic control board |
| UE | Unbalanced load | Redistribute the garments in the washer. If the load is too small to be balanced, increase the load size. Heavy items mixed with light ones may not balance properly. Make sure the washer is properly leveled | |
| OE | Drains slowly | Check the washer drain for a clog. Check the drain hose for a kink or restriction. Unplug the washer and check the wire harness connection between the electronic control board and the drain pump. Reconnect any loose wires or replace the wire harness if damaged. If the drain pump doesn't run when activated, replace it | Drain pump, wire harness |
| FE | Water overflow error | The drain pump runs constantly when the FE error code is displayed. Check the inlet water valves to see if they shut off the water supply properly after the washer is filled. If the inlet water valves are defective, replace the inlet water valve assembly | Inlet water valve assembly |
| PE | Water level sensor failure | Unplug the washer and check the wire harness connections between the water level sensor and the electronic control board. Reconnect any loose wires or replace the wire harness if damaged. If the wire connections are okay, replace the water level sensor | Water level sensor, wire harness |
| dE | Door is open error | Unplug the washer. Check the door for an obstruction. If the door is damaged, replace any defective parts. If the door is closing properly, check the door lock/switch assembly wiring. If the wiring connections are sound, replace the door lock/switch assembly | Door lock/switch assembly, Washer door components |
| tE | Heating sensor error | Unplug the washer. Check the wiring connections on the drum thermistor (temperature sensor). Measure the resistance using a volt/ohm meter. It should measure about 40,000 ohms at 85 degrees F. If the thermistor is defective, replace it. Check the heating element for damage. If the heating element is defective, replace it | Drum thermistor, Heating element |
| LE | Locked drive motor error | Check the wire harness connections on the motor and the hall sensor (tachometer). Repair any wiring failures. If the wiring connections are sound, check for damaged motor components. Replace any damaged motor components. If there are no problems found with the motor, replace the hall sensor | Drive motor components, Hall sensor (tachometer) |
| EE | EEPROM error on main electronic control board | The EEPROM (Electrically Erasable Programmable Read-Only Memory) on the control board is corrupted. Try to clear the code by unplugging the washer for 5 minutes. If the code doesn't clear when you restore power, replace the main control board | Main electronic control board |
| PF | Power failure | A power failure occurred during the cycle. The cycle may not have completed properly. Start a new cycle |
