Bosch Dishwasher Error Code 1001

Error code 1001 on a Bosch dishwasher means the inverter has detected a power stage short circuit. The inverter is the electronic board that controls the wash pump motor. The dishwasher shuts down when this fault occurs to protect the system from further electrical damage. Resolving this code requires inspection and typically replacement of the inverter board.

A reset will not resolve error code 1001. Because this fault is caused by a physical short circuit in the inverter's power stage or connected components, the fault condition will remain and the code will return as soon as the dishwasher attempts to operate the wash pump. The underlying hardware fault must be repaired before the error will clear permanently.

Repair costs for error code 1001 vary depending on whether the inverter board, the wash pump motor, or both need replacement. Inverter board parts alone can range from roughly $80 to $250 or more depending on the model, and labor costs typically add $100 to $200 depending on your area. If the motor also requires replacement, total repair costs can be higher, making it worth evaluating the repair cost against the age and value of the appliance.

Diagnosing and repairing error code 1001 involves working with the dishwasher's main power electronics, which requires disconnecting the appliance from power and handling circuit boards and motor components. A technician with appliance repair experience can inspect the wiring harness and replace the inverter board. Most homeowners are not equipped to safely perform this repair and should contact a qualified technician.

No, you should not attempt to operate the dishwasher while error code 1001 is active. A power stage short circuit is a serious electrical fault that has caused the machine to shut down as a protective measure. Continuing to cycle power and force operation could worsen damage to the inverter, motor, or associated wiring and could create a safety hazard.
