Bosch Dishwasher Error Code dr:02

The dr:02 code on a Bosch dishwasher indicates an IGBT interruption, meaning a critical power-switching transistor on the control board has been damaged or has failed. The IGBT is an internal component of the control board and cannot be repaired separately. The control board must be replaced to resolve this fault.

No, the dishwasher should not be used while displaying dr:02. The control board damage means the appliance cannot properly regulate power to its internal components, and continued attempts to run it could cause further damage. Disconnect power to the unit until the control board has been replaced.

No, resetting or power-cycling the dishwasher will not clear the dr:02 error. This code is caused by physical hardware damage to the IGBT transistor on the control board, and that damage persists regardless of any software reset. The fault will return immediately because the underlying component failure has not been corrected.

Resolving dr:02 requires replacing the control board, which involves working with electrical components and disconnecting wiring harnesses inside the dishwasher. A confident DIYer with appliance repair experience may be able to perform this replacement, but if you are not comfortable working with appliance electronics, a qualified technician is recommended.

The cost to repair a dr:02 error depends primarily on the price of the replacement control board and labor if a technician is hired. Control board parts for Bosch dishwashers typically range from around $150 to $350 or more depending on the model. Professional labor can add another $100 to $200, bringing the total repair estimate to roughly $250 to $550 in many cases.
