LG Washer Error Code E-2A

E-2A on an LG washer indicates a temperature sensor short error variant. The control board has detected that both terminals of the water temperature sensor are in a slightly shorted condition, producing an abnormally low resistance reading. This prevents the machine from accurately monitoring water temperature, so it stops the cycle as a protective measure.

It is not recommended to continue running the washer with an active E-2A error. Without a functioning temperature sensor, the control board cannot properly regulate water temperature, which could result in inadequate cleaning or, in machines with heating elements, a risk of overheating. Addressing the fault before resuming use is the safer course of action.

Repair costs depend on the root cause. A replacement thermistor is generally an inexpensive part, often in the range of $15 to $40 for the component alone. If a technician is needed, labor charges typically bring the total to somewhere between $100 and $200 depending on your location. A control board replacement, if required, would be significantly more costly, potentially ranging from $200 to $400 or higher including labor.

In some cases, yes. Start by unplugging the washer and inspecting the temperature sensor connector for moisture, corrosion, or damaged wiring. If the wiring harness is intact and the connector is clean, test the sensor terminals with a multimeter to check for a short. Replacing the thermistor is a moderately accessible repair for someone comfortable with basic appliance disassembly and using a multimeter.

A reset, typically done by unplugging the washer for a few minutes and then reconnecting power, may temporarily clear the code. However, if the underlying sensor short condition still exists, the error will return once the washer attempts to read the sensor during a new cycle. A reset alone is not a repair and should only be used as part of diagnosing the issue.
