Enviro M55 Porcelain problem

Bin a while since I last posted, but I am having a weird problem with my Enviro M55 Insert.
I noticed some chipping on the porcelain and immediately blamed the wife. She insisted that she did not bump into it with the vacuum of anything else for that matter. I was a bit suspect but had no proof. Next day I noticed more chipping of the porcelain on the door. No flecks on the floor in front just more and more porcelain peeling off and disappearing. I now believe my wife but have no idea why the porcelain on the door of my M55 is disappearing. The only thing that I noticed over the past week or so is a faint smell of smoke in the house and a couple of loud cracking sounds after a few hours of running.
Has anyone else experienced this issue with your M55 Insert????
I have not contacted my dealer and I think I am still under warranty but it is really bothering me since i can not figure out what might be going on here.
Any ideas????
Thanks

I have the plain cast, so no problems with mine.

"Immediately blamed my wife" - that was good for a few laughs with my wife this morning! Thanks.

curious about this.....often finishes are excluded from warranty

There are some other limitations(of coarse) But it looks as though if it is deemed a defect. You might get a replacement, if its under 1 year old?

OP first posted in Jan, 2011, and stated in the first post that his stove was a year old then........the plot thickens......I wonder why after 2 years it would start flaking......better waterboard your wife, Freddo!
