Daewoo Washer Error Code lb

The lb error code on a Daewoo washer indicates an IGBT error, meaning the power transistor responsible for controlling the motor drive circuit has failed. This fault is located on the PCB assembly, and the control board is considered defective when this code appears. The washer will not operate normally until the issue is resolved. Replacement of the PCB assembly is the prescribed repair action.

No, the washer should not be used while displaying the lb error code. A failed IGBT on the control board means the motor drive circuit is compromised, which could lead to unpredictable motor behavior or additional component damage. Power the unit off and disconnect it from the outlet until repairs are completed.

Repair costs for an lb error depend primarily on the price of the replacement PCB assembly, which typically ranges from around 80 to 200 dollars or more depending on the model. Adding professional labor for diagnosis and installation can bring the total repair estimate to somewhere between 150 and 350 dollars. Getting a cost estimate from a technician before proceeding is advisable, especially on older machines.

The lb error requires replacement of the PCB assembly, which involves working near high-voltage components. A knowledgeable DIYer comfortable with appliance board swaps can complete the replacement, but the work should be done with the washer fully unplugged. Sourcing the correct replacement board for the specific Daewoo model is essential before attempting the repair.

A simple reset is unlikely to permanently clear the lb error because it indicates a hardware failure in the IGBT circuit on the control board. The code may temporarily disappear after a power cycle, but it will return as soon as the washer attempts to run the motor. The underlying board fault must be corrected through PCB assembly replacement.
