LG Washer Error Code E-22

E-22 on an LG washer indicates a temperature sensor short error. The washer's control board has detected that the terminals of the temperature sensor are shorted together, producing an invalid resistance reading. This prevents the machine from accurately monitoring water temperature, so it stops operation and displays the code. The sensor, its wiring, or the connector will need to be inspected and the shorted component removed or replaced.

No, you should not continue running the washer while the E-22 code is active. A shorted temperature sensor means the control board cannot accurately track water temperature, which could result in water being heated beyond the intended range. Continuing to operate the machine in this condition risks damage to fabrics and potentially to internal components.

A reset may temporarily clear the E-22 code, but the error will return as soon as the washer attempts to read the temperature sensor again if the underlying short has not been corrected. To permanently resolve the error, the shorted sensor terminal, wiring, or component must be physically identified and repaired or replaced before the code will stay clear.

Some DIY repair is possible depending on the cause. If the short is in an accessible connector or a visible section of wiring, a knowledgeable DIYer can disconnect the sensor, inspect both terminals for bridging, and repair or replace the affected component. If the thermistor itself has failed internally, it will need to be replaced, which typically requires basic disassembly of the washer cabinet to access the sensor location.

Repair costs vary depending on the root cause. If only the wiring or connector needs to be cleaned or repaired, costs are minimal, primarily the cost of your time or a service call fee ranging from $50 to $100. If the temperature sensor needs to be replaced, parts typically cost in the range of $15 to $50, and a professional repair including labor could run $100 to $200 depending on your location and the technician's rates.
