Bosch Dishwasher Error Code 1111

Error code 1111 on a Bosch dishwasher indicates an inverter error caused by a software fault inside the inverter module. The inverter controls the wash pump motor speed and operation. When its internal software encounters an unrecoverable condition, this code is triggered and the appliance stops running. Replacement of the inverter is the recommended resolution.

A standard power reset, such as unplugging the dishwasher or turning off the circuit breaker for a few minutes, is unlikely to permanently resolve error 1111. Because the fault is described as a software error internal to the inverter module, the error condition typically persists or returns immediately after reset. If the error clears briefly but reappears, the inverter module itself is the failed component.

Repair costs for error 1111 depend on the cost of the replacement inverter module and labor charges in your area. Parts alone for an inverter module can range from roughly 80 to 250 dollars depending on the specific Bosch model. With professional labor, total repair costs typically fall somewhere in the range of 150 to 400 dollars. Getting a quote from a certified technician before proceeding is advisable.

Error 1111 is diagnosed as an internal software fault within the inverter, and the recommended fix is replacement of the inverter module. While a knowledgeable DIYer can inspect wiring connections to the inverter as a preliminary step, the inverter itself typically requires replacement. Sourcing the correct inverter part and safely accessing it inside the dishwasher requires comfort working with appliance electronics and disconnecting power before servicing.

You should not continue running the dishwasher while error 1111 is active. The inverter controls the wash pump motor, and operating the appliance with a faulted inverter risks further electrical damage. The dishwasher will typically halt its cycle when this code appears, which is a protective response. Have the inverter inspected and replaced before resuming use.
