I have a 5 year old Wolf 30" wall oven. The glass door contunually fogs and after using the self clean setting yesterday the blue porcelain floor of the oven has begun to peel off leaving an exposed metal surface. Customer service knows of the problem and refuses to do anything about it. I am questioning why I purchased an appliance in excess of $4000 to have it self destruct in a few years. To be sure I will never purchase another Wolf product. Unfortunately I also own a Sub Zero fridge and a 36" Wolf gas range. Anyone one else have a similar problem?
