Bosch China scrap

I have received the microwave today and wanted, as mentioned in the instructions, do a test run with a cup of water - ie pressed 800W button, set 1:30 min, pressed start button. Everything went like a regular microwave just that after cooking the water was really nice and cold ... great quality. What the old Bosch would have said this - "Technology for the scrap heap" possibly

Is also disturbing that the fan runs for a relatively long time - even if the food was not heated.
