LG Washer Error Code bE3

The bE3 code indicates a main relay error on the main PBA (printed board assembly). It means the control board has detected that the main relay is short-circuited, has a bent or improperly connected terminal, or the motor relay is not operating as expected. The washer stops running to prevent electrical damage until the fault is resolved.

A simple power reset is unlikely to permanently clear the bE3 code because it points to a hardware fault in the relay circuit rather than a temporary software glitch. The code will typically return as soon as the washer attempts to power the motor again. The underlying relay or connection issue must be corrected before the error will stay cleared.

If the repair only requires reseating or straightening a bent relay terminal, the cost could be minimal beyond a service call fee, generally in the range of $75 to $150. If the main PBA needs to be replaced, parts and labor combined typically run between $200 and $400 depending on the specific model and local labor rates. Getting a diagnosis before ordering parts is advisable since board prices vary significantly by model.

A knowledgeable DIYer can start by inspecting the relay connections on the main PBA for bent terminals or loose connectors, since a connection issue can sometimes be corrected without replacing parts. However, if the connections look correct, the main PBA itself needs to be replaced, which involves working near line-voltage components. If you are not comfortable working inside the washer's electrical panels, a qualified appliance technician is the safer option.

No, you should not continue running the washer with an active bE3 error. A shorted or malfunctioning relay in the power circuit can cause overheating, board damage, or an electrical hazard. The washer should remain unplugged until the relay connections have been inspected and the fault corrected.
