The Siemens HB556ABS0 is a spacious oven with 7 rack levels and various oven and grill functions. Use the dials to easily set the temperature and preparation time. The dials light up as the oven turns on. Not quite sure which settings you need for for your dish? The oven also features automatic settings that will select the right temperature and preparation time for your dish. When you're done cooking, all you have to do is wipe down the oven walls: the oven features catalytic walls that absorb and burn grease. Thanks to the special coating, food remains won't build up in the oven either.
