7.6 Heating elements
The heating elements should be cleaned regularly after they have cooled down. Remove dirt adhering
to the plate with e.g. ethanol. Then clean the plate with a moist cloth and dry it.
ATTENTION
Never use scratching sponges, cleaning pads or cleaner containing abrasives to clean the heating
elements as they might damage the surface.
