I'm not familiar with that particular model, but it probably means that there is an internal fault. i.e. faulty door switch, blown fuse, or H.V. fuse. Possibly even a faulty magnetron, or capacitor. You could contact the manufacturer who should give you the list of error codes and what they mean. Once you know, it would be much easier to fix.
Some codes are just plane vague, and you have to spend time testing everything.
