Bosch Dishwasher Error Codes
If your Bosch dishwasher displays an error code, it means the appliance has detected a fault during operation. Modern dishwashers use diagnostic systems to identify problems with components such as drainage systems, water supply, heating elements, sensors or electronic control boards.
Understanding what these error codes mean can help you identify the cause of the problem and determine whether a simple reset or basic check may resolve the issue before contacting a technician.
Try This First (Quick Reset)
• Turn the dishwasher off at the mains
• Leave it for 2–3 minutes

This can clear temporary faults and save you an unnecessary repair.
