10 fault codes documented
Arcing in the microwave oven
Sparks or arcing are visible inside the microwave oven cavity during operation. This is typically caused by food soil buildup or debris.

A message in the display indicates that the microwave door has been closed for five minutes or longer without starting a cooking cycle. This safety feature prevents unintended operation.

The display shows a combination of a letter and a number, which signifies a general error within the microwave oven system. This type of error typically requires professional assistance.
Cooling fan running during cooktop usage — Normal operation
