I have two Wolf Ovens, one electric, self cleaning and one gas, not self cleaning. Purchased in 2006.
Both have large chips coming off the bottom of oven. Wolf calls them tiny cracks called Crazing. Mine are not "tiny". They won't even offer to come see.
They tell me it will not affect performance! It certainly affects the appearance and at this rate of cracking it won't be long before the whole bottom of oven is involved. Part of the purchase of "high" end products are the appearance.
I can't believe this is ok. I am unhappy about lack of concern from Wolf.
