Loved my tramontina 3 piece induction system from Costco until this happened. Was boiling some eggs as I do every morning and had done for 9 days in a row with this system. This morning I might have had the temperature a little higher but not much more. When the water came to a rolling boil I put 2 eggs in. When it was time to pull them out I shut off the cooktop and went to pull off the lid, but I couldn't because it was stuck. I thought that maybe it needed to cool down so I left it alone now 12 hours. However the lid is still stuck to the pot. I do not wish to force it. I have even held it upside down as pictured.
