LG Washer Error Code E-02

The E-02 code on an LG washer with a combined microwave oven mode means the cook time you entered for the MWO function exceeds the maximum setting allowed by the unit. It is a parameter validation error, not a mechanical or component failure. Pressing the Cancel key clears the error, and you can then re-enter a cook time within the accepted limit.

The E-02 error is a non-critical input error that prevents the unit from operating outside its programmed limits. The appliance is designed to stop and display this code rather than proceed with an out-of-range setting, so there is no immediate safety risk. Simply cancel the current state and re-enter a valid cook time before using the microwave mode again.

In most cases, there is no repair cost because E-02 is typically resolved by simply pressing Cancel and entering a valid cook time. If a faulty keypad is causing unintended time values to be registered, keypad replacement parts and labor can range from roughly 50 to 150 dollars depending on the specific model and service provider. A control board replacement, if needed in rare cases, can range from 150 to 350 dollars or more including labor.

Press the Cancel key to clear the current error state and return the unit to standby mode. Once cleared, re-enter a cook time value that is within the microwave mode's maximum allowable range. If the error reappears even when entering a short or minimal cook time, inspect the keypad for stuck buttons or contact a technician to evaluate the control board.

Yes, pressing the Cancel key is the recommended way to reset the E-02 error and return the unit to a ready state. A full power cycle by unplugging the unit for a few minutes may also clear the error display. However, the code will return if an out-of-range cook time is entered again, so the root input issue must also be corrected.
