Reheat (dish with heat or steam)

Brings cooked, chilled food back up to eating temperature. On Bosch and Siemens steam ovens it adds steam so the food does not dry out.

What it is for

Cooked food stored in the fridge (Smeg), plated meals and baked items (Bosch), crisping up pastries (Siemens).

Makes differ, check your oven’s manual: the same drawing can mean different things on different brands, and only your model’s manual says exactly which elements run and how hot.

What it looks like
A dish with heat or steam rising from it. Bosch adds a steam cloud above the wavy lines; Siemens draws a cloud over a fan and a dish.
Names makers use
