Fault codes, also called error codes or fault codes, allow your device to automatically report an internal malfunction. Below you will find the list of fault codes for your Bosch oven and their meaning: this will give you an indication to best diagnose the origin of the malfunction of your appliance.
The error code can be read directly on the front panel of your Bosch oven – cooker. Depending on the model, you can read this code on a display (for example, “Err 01”) or by observing the number of LED flashes (for example: 4 LED flashes = “Err 04”).
Refer to the instructions for your Bosch appliance to find out the exact meaning of the fault code displayed or the lights that flash. The number of flashes often corresponds to the error code number, but there are specificities linked to each model and brand.
