LG Washer Error Code E-04

The E-04 code on an LG washer indicates that the cooking time entered for convection mode exceeds the maximum allowed duration of 45 minutes. This is a control system input validation error, not a hardware fault. The appliance will not proceed with the cycle until the time setting is corrected. Press Cancel to reset the current state and re-enter a valid time at or below 45 minutes.

Yes, the E-04 error does not indicate any electrical or mechanical hazard. It is a parameter input error that the appliance uses to prevent operation outside its programmed limits. Once you cancel the error and enter a valid time, the appliance is safe to operate normally.

In most cases, there is no repair cost at all since E-04 is caused by an incorrect time entry rather than a failed component. If the error persists after canceling and re-entering valid settings, and a control board fault is suspected, board replacement costs can range from around $150 to $400 or more depending on the model and labor rates in your area.

Press the Cancel key to clear the current error state and return the appliance to standby. Then re-select convection mode and enter a time setting that does not exceed 45 minutes. No tools or replacement parts are needed to resolve this error in most cases.

Pressing the Cancel key is the recommended way to clear the E-04 error, and it should resolve the condition immediately. A full power reset by unplugging the unit can also clear the fault if the Cancel key does not respond. However, the error will return if you re-enter a convection mode time setting above 45 minutes.
