Breaks in enamel finish of (relatively) new Wolf oven?
We have 30" Wolf wall ovens that have been in 2.5 years. They don't get especially heavy use (light to normal I would say -- many days they are never turned on at all because we grill or use the gas rangetop), and we've only had to run the self-clean perhaps a half dozen times since we've had them. We noticed recently that on the floor of the upper oven, that beautiful bright blue enamel had what for the world looked like scrape marks (except that NO ONE has scraped it with anything at all, much less something seriously metallic which is what it would take to dig into the enamel) toward the left rear. Sort of a small clump of lines where the enamel is clearly broken. Just ran the self-clean on that oven last night, and found a new area, looking identical, of "scrapes" at the front center. The enamel actually came off in bits when we wiped down the oven with a damp paper towel post-cleaning. These areas do not correspond in any way to the "feet" of the pizza stone element, which we have used occasionally. They seem to be completely random in location.
So my question is whether anyone else has had problems with the interior finish of their Wolf ovens. We have called Wolf and they are looking into it. The ovens are obviously JUST out of warranty by a few months, so incredibly annoying and we hope they will (a) have an answer as to what might have caused this and (b) stand behind their product. This is on top of already having replaced the complete electronic control panel for these ovens once. To say we are unimpressed with the quality of these ovens so far, especially for the price!, is an understatement.
