Bosch Dishwasher Error Code 1000

Error code 1000 on a Bosch dishwasher indicates an inverter fault related to the current null range. This means the inverter, the electronic module that drives the wash pump motor, has detected an abnormal condition in its current regulation circuitry. The dishwasher shuts down to prevent damage, and in most cases the inverter module will need to be replaced.

No, you should not continue operating the dishwasher once error code 1000 appears. The dishwasher shuts itself down when this fault is detected specifically to prevent further damage to the motor or electrical components. Running cycles while this fault is active could worsen the failure and increase repair costs.

Repair costs for error code 1000 typically depend on the price of the replacement inverter module and labor time. Parts and labor combined can range from around $150 to $400 or more, depending on the specific Bosch model and local service rates. It is worth comparing the repair estimate against the age and overall condition of the dishwasher before proceeding.

This repair is generally best handled by a qualified technician because it involves diagnosing and replacing the inverter module, which is an electronic component connected to the motor drive system. A knowledgeable DIYer can check the wiring harness and motor connections as preliminary steps, but the inverter itself requires replacement if those checks pass. Working with dishwasher electronics also involves safely disconnecting the appliance from power before any inspection.

A reset may temporarily clear the fault display, but the error code 1000 will return as soon as the dishwasher attempts to run the wash pump, because the underlying inverter hardware failure remains. Resetting does not repair the inverter. The fault must be resolved by inspecting the wiring and motor and, in most cases, replacing the inverter module.
