LG Washer Error Code EE3

EE3 on an LG washer indicates a fault with the main relay on the Printed Board Assembly (PBA). The code is triggered when the relay is short-circuited, when terminal connections are incorrect, or when a bent terminal is preventing proper contact. Because the motor relay is not operating, the washer cannot complete its cycle. Repair requires inspecting the relay terminals and the PBA itself.

No, you should not continue using the washer while EE3 is active. A shorted main relay or failed motor relay circuit can result in uncontrolled power delivery to internal components, which poses a risk of further electrical damage or, in severe cases, a fire hazard. Leave the washer unplugged until the fault is diagnosed and corrected.

Repair costs vary depending on the root cause. If the issue is simply a loose or bent terminal that can be corrected without parts, labor costs alone typically range from $75 to $150 depending on your location and service provider. If the PBA needs to be replaced, the total cost including parts and labor generally falls in the range of $200 to $450. Getting a diagnostic estimate before authorizing repairs is recommended.

A knowledgeable DIYer can start by inspecting the relay terminal connections on the PBA for loose, bent, or misaligned pins and reseating them if needed. However, if the relay is internally shorted or the board is damaged, replacing the PBA is typically required and involves working with line voltage components. If you are not comfortable working with electrical components, a qualified technician should perform the repair.

A power reset, such as unplugging the washer for a few minutes and restarting it, may temporarily clear the code if the fault was caused by a transient electrical condition. However, if the main relay is shorted or a terminal remains bent or improperly connected, the EE3 code will return once the washer attempts to operate. A physical inspection and repair of the relay circuit is necessary for a lasting fix.
