The cooktop regulates the heating element temperature by turning the heat source on and off; This means that the heat source beneath the heating element, which gives off a reddish glow, may not always be visible. If you select a low heat setting, the heat source is frequently off; at higher settings it is seldom off. The source turns on and off even at the hottest setting. You may hear a quiet hum when the heating elements are in the heating phase. The heating elements may glow with different levels of brightness. Depending on the angle from which you are looking at the heating element, this glow may be visible over the marked edge of the heating element. These are technical characteristics. They have no effect on quality and function. Depending on the countertop that is present in the kitchen, an uneven gap between the cooktop unit and the countertop can occur. For this reason, a flexible seal is provided around the entire cooktop unit. Glass ceramic may have uneven areas on the surface due to the nature of the material itself. Because of the mirrorĆlike finish on the cooking surface, even extremely small bubbles less than 1 mm in diameter may be visible. These bubbles will not have any adverse effect on the operation of the cooktop nor on the durability of the glass ceramic cooking surface. 19
