Our mixers do not allow hot pans or pots to be located under the mixing arm. You should always cook/heat ingredients in a different pan and then pour the content of your vessel into the mixing bowl that comes with the kitchen machine (or any compatible bowl model, glass or stainless steel): the provided KW bowl is the only tool guaranteeing safe and stable fixing by locking the bowl into position to the mixer base. Both the glass bowl and the stainless steel bowl are safe with hot mixtures.
