Bosch Dishwasher Error Code 1011

Error code 1011 on a Bosch dishwasher indicates an inverter fault caused by an IGBT short circuit or open circuit. The IGBT is a power transistor inside the inverter module that controls the wash pump motor. When this component fails in either direction, the dishwasher cannot operate the pump and displays this code. Replacing the inverter module is the prescribed corrective action.

A reset will not clear error code 1011 permanently because the fault is caused by a hardware failure within the inverter module, not a software glitch. The code will return as soon as the dishwasher attempts to run the wash pump again. The inverter must be replaced to resolve the error.

The cost to repair error code 1011 depends on whether you hire a technician or do the work yourself. The inverter module part itself typically ranges from around 80 to 200 dollars depending on the specific model. Adding professional labor, total repair costs generally fall in the range of 150 to 350 dollars. Getting a quote before committing is recommended, especially on older units where repair costs may approach replacement value.

A knowledgeable DIYer comfortable working with appliance electronics can replace the inverter module themselves. The repair involves disconnecting power, accessing the inverter, disconnecting the wiring harness, and installing the replacement unit. However, because the inverter handles high-voltage power conversion, anyone not confident working around these components should hire a qualified technician.

The dishwasher will typically prevent normal operation when error code 1011 is active, so running a wash cycle is not possible in most cases. Attempting to force operation with a known inverter fault is not advisable, as a shorted IGBT can cause additional damage to connected components. The safest course of action is to keep the unit off until the inverter has been replaced.
