Bosch Washing Machine Error Codes

Fault codes, also known as error codes, enable your Bosch washing machine to automatically report internal malfunctions. Below is a comprehensive list of error codes and their meanings to help you diagnose potential issues with your appliance.

The error code appears on the front panel of your Bosch washing machine. Depending on the model, it may be displayed as text (e.g., “Err 01”) or indicated by a specific number of LED flashes (e.g., 4 flashes = “Err 04”).

For precise interpretations of fault codes or LED indicators, refer to your Bosch washing machine’s user manual. While many codes correspond directly to the number of flashes, variations may exist depending on the model.
