It has been happening since day 1 because the design Is flawed.The appliances were provided by the builder as an upgraded package.
The grates of this cooktop are so high that it makes the 4 corner burners useless. It takes 15 minutes to boil a cup of water . The middle one is so big that it will burn the handles of the pots/pans . And I use normal sized pots and pans needed for an average family of four.
I contacted the customer service multiple times and they recommended me to look for lower grates in Lowe/home depot since they do not recommend any other grates or buy another cooktop.The cooktop is just over a year old and they do not stand behind their flawed design or help !Model - KCGS556ESS Serial - D54414553
