This was bought for me as a wedding present 5 years ago now. It’s gone through the dishwasher maybe five times in it’s life span, I usually wash it by hand unless there is space in the dishwasher. I don’t have a high performance dishwasher, no sanitize button or hi temp dry option…so there is no valid reason the dishwasher safe insert should bubble and peel. When I pulled it out of the wash this morning the edge felt like it had food left on it, so I went to scrub it and discovered that the entire brim and some of the inside bubbled. I don’t leave the crock pot on longer than I cook the food, there is no exposure to heat without food in it. I’m extremely disappointed that a high end product put out by a company with a solid reputation is not only doing this, but that the warranty specifically won’t cover it…to me that supports the idea that the company knew this was going to happen.
