LG Washer Error Code E-13

The E-13 code on an LG washer indicates a gas sensor T1 maximum time error, meaning the humidity sensor did not detect moisture within the expected time during a cycle. This can be caused by an empty drum, a contaminated sensor surface, or a faulty sensor. The machine stops operation and displays this code to prevent running under abnormal conditions.

A reset may temporarily clear the code, but if the underlying cause is not addressed, the error will return when the next cycle runs. Resetting is useful as a first step to confirm whether the fault was a one-time event, but persistent E-13 errors require physical inspection of the sensor and drum load. Resolving the root cause before resetting gives the best chance of permanent resolution.

If the fix is simply cleaning the sensor or ensuring a proper load is used, there is no parts cost involved. If the T1 humidity sensor needs replacement, parts alone typically range from around $15 to $60 depending on the specific model and supplier. Adding professional labor for diagnosis and replacement can bring the total repair cost to somewhere between $80 and $200 in most cases.

Start by confirming that laundry was actually loaded into the drum, since an empty drum will not generate the humidity the sensor expects. Next, locate the T1 humidity sensor and inspect it for any residue, lint, or debris on its surface, then clean it gently. If the error continues after these steps, the sensor or its wiring connection may need to be tested and possibly replaced.

The appliance stops its cycle when E-13 is displayed, so it will not continue operating in a potentially abnormal state. It is generally safe to inspect the sensor and drum, but you should not attempt to bypass or ignore the error and force the machine to run. Address the cause of the code before resuming normal use.
