"We are sorry you are experiencing warping. It is very common for griddles to expand and contract during heating and cooling, and in some cases with thermal shock the griddle can warp or pop-up temporarily, but will correct itself. This is likely to occur in the first couple months of use but will correct itself with continued use. You can reduce the impact by only placing room temperature foods on the griddle, never placing food right from the fridge or freezer onto the surface, and also not pouring water on the surface for cleaning. If your griddle is not correcting itself and going back to its original shape and/or is continuing to warp. Please reach out to customer service by phone or email. We would be happy to address any issues you are having. We can be reached at: 1-833-454-0864 or via email at: support@proseriesbbq.com.
