Bosch Dishwasher Error Code 0101

Error code 0101 on a Bosch dishwasher indicates an inverter phase loss fault. The inverter module, which drives the wash pump motor using a three-phase output, is detecting that one or more of its output phases is missing or not reaching the motor. The dishwasher will not operate normally until the fault is resolved.

No, you should not attempt to run the dishwasher while this fault is active. The error indicates a failure in the motor drive system, and continued operation attempts could cause further damage to the inverter, motor, or associated wiring. Leave the unit powered off until the fault is diagnosed and repaired.

Repair costs vary depending on the root cause. If the fix involves reseating a connector or replacing a damaged harness section, costs are relatively low, typically in the range of $50 to $150 for a service call plus any minor parts. If the inverter module requires replacement, parts and labor can range from $200 to $450 or more depending on the specific model and local labor rates.

Some causes of this error are DIY-accessible, particularly inspecting and reseating connectors or checking the wire harness for visible damage. However, if the inverter module or wash pump motor needs replacement, those repairs require comfort working with electrical components and disassembly of the appliance interior. If you are not confident with appliance electrical diagnostics, a qualified technician is recommended.

A reset may temporarily clear the displayed code, but the error will return as soon as the dishwasher attempts to run and the inverter detects the phase loss condition again. A reset does not address the underlying electrical fault. Proper diagnosis and repair of the inverter, wiring, or motor is required for a lasting fix.
