I have an older Miele Turbothermic G572, but it has not been used a lot. My problem is very dangerous, and I have just unplugged the machine except when I need it, but cannot continue like that. Based on some of the/your prior answers, it sounds like a heating temperature monitor or something like that is out of wack.
any clues? I would also like a manual or photos to help describe what parts to check out.
