  • Page 81: Stains On Glass Surface Or The Inductors

    5.13 Stains on glass surface or the inductors Frequently the stains are actually not stains at all, but stubborn dirt which disappears when cleaned with the glass scraper and a suitable detergent. (Fairy and a BSH product for cleaning ceramic surfaces.) On the website of the brand manufacturers is a video on the subject of cleaning which may help us explain to the user how to clean ceramic surfaces.
  • Page 82 5.13.2 Repair due to utensils left to stand First, we clean the glass with Fairy, glass scraper and the BSH detergent for ceramic surfaces. It is also very important to check whether the inductors are in perfect working order. Even if they perform correctly, check that the NTC resistors are in perfect working order to avoid subsequent problems.
  • Page 83 5.13.3.1 Solution The glass must be replaced with a new one. Procedure: 1. Remove old glass surface. 2. Apply heat transfer compound to the NTC resistors (618647). 3. Cover heat transfer compound with foil (which comes together with the glass spare part set) to prevent contact with the new glass surface.

    5.14 What is to be considered when using induction 5.14.1 Levelness cookware If a thick and level base is selected, i.e. pans with stainless steel  Use pans which have a thick and level base so that they are in sandwich base, the heat distribution is much better, saving time full contact with the cooking surface.
  • Page 85 Each cooking zone has a pan detection minimum limit. This value Never use pans made of: cannot be calculated exactly, as behaviour depends on the material of the pan used. We therefore recommend using the zone which Normal stainless steel corresponds most closely with the diameter of your pan.
