What the dr:01 error code actually means

Your dishwasher has detected a burned-out or failed electrical component inside its control board, which is the brain of the appliance. This type of failure cannot be reset or repaired by the homeowner, and the dishwasher will not run until the control board is replaced. A qualified technician will need to source and install a new control board to restore normal operation.

Questions people ask about dr:01

What does dr:01 mean on a Bosch dishwasher?
The dr:01 code indicates an IGBT short circuit inside the main control board. The IGBT is a power-switching transistor that regulates current to the dishwasher's motor and other high-load components. When it fails in a shorted state, the control board detects the fault and shuts down the appliance. This code requires control board replacement to resolve.
Is it safe to use my Bosch dishwasher with the dr:01 error showing?
No, you should not attempt to run the dishwasher while the dr:01 code is active. A shorted IGBT can cause uncontrolled current flow, which risks additional damage to the wiring harness or other connected components. Discontinue use until the control board has been replaced.
Will resetting my Bosch dishwasher clear the dr:01 error?
No, a reset will not clear the dr:01 error or restore normal operation. This code reflects a hardware failure, specifically a shorted transistor inside the control board, not a software glitch or temporary sensor fault. The error will return immediately or the dishwasher will remain non-functional until the control board is physically replaced.
Can I fix the dr:01 error myself?
This error points to an internal failure of the control board, specifically a shorted IGBT transistor. Because the faulty component is soldered onto the board and not a user-serviceable part, the repair requires full control board replacement. Most homeowners will need a qualified appliance technician to source the correct board and complete the installation safely.
How much does it cost to fix a dr:01 error on a Bosch dishwasher?
Repair costs vary depending on the specific model and labor rates in your area. Control board parts alone typically range from $150 to $400, and professional installation labor can add $100 to $200 on top of that. In some cases, the total repair cost may warrant comparing against the price of a replacement dishwasher, particularly on older units.
