Below the glass surface there are electric components which can cause electric shock and also be damaged beyond repair by water or oil which can get through the cracks.

Here are some recommendations how to prevent breaking the glass on your cooktop:

  • Avoid storing jars or cans above the cooktop
  • Do not leave a hot lid on the cooktop
  • Clean up all spills and soils as soon as possible
  • To avoid scratches, do not slide cookware across the cooktop
  • Do not allow objects that could melt, such as plastic
  • Do not use the cooktop as a cutting board
  • Cookware should not extend more than 1.3 cm outside the marked cooking area
