LG Washer Error Code E-11

E-11 on an LG washer indicates a gas sensor open error, meaning the control board cannot detect any signal from the gas sensor. This is an open circuit fault, not an out-of-range reading. The machine stops operation because this sensor is part of the gas drying safety system. The fault points to the sensor itself, its wiring, or the connector at the PCB.

It is not recommended to continue using the appliance while the E-11 error is active. This code relates to a gas sensor that is part of the drying system's safety monitoring. Operating the unit with a non-functional gas sensor bypasses an important safety check. The machine should remain out of service until the sensor circuit is inspected and repaired.

Repair costs vary depending on what component has failed. If the fix is simply reseating a loose connector, a service call fee may be the primary expense, typically in the range of $75 to $150. If the gas sensor itself needs replacement, parts and labor combined could run anywhere from $150 to $350 or more depending on your location and the technician's rates. A full diagnostic visit will clarify exactly what needs to be replaced.

Start by checking the gas sensor connector at both the sensor housing and the PCB to make sure both ends are fully seated and undamaged. Inspect the wiring harness for any visible breaks, pinching, or corrosion on the terminal pins. If the connections are secure and the wiring is intact, the gas sensor component itself likely needs to be tested and replaced. A repair technician can perform continuity testing to confirm which component is at fault.

A reset is unlikely to permanently clear the E-11 error because it is caused by a hardware fault in the sensor circuit, not a temporary software glitch. The error will return as soon as the machine attempts to detect the gas sensor and finds the circuit still open. The underlying cause, whether a loose connector, damaged wire, or failed sensor, must be corrected before the code will stay clear.
