Bosch equipment is famous to be one of the most reliable and long-lasting. Yet even the high-quality appliances need maintenance and repair services from time to time. The team of professional and skilled technicians will identify the problem type, remove the problem and replace spare parts if needed. New Bosch ovens differ from the old one with their ability to show the occurred problems. They have self-diagnostic programs. The ovens are equipped with the electronic display.

An owner may see the error number and find the error number in the manual. Neither the owner nor a technician has to spend time searching for a problem. Their task is to resolve a problem. Let`s have a look at some most widespread ovens errors manufactured by the German company Bosch:
