Abstract

A method for preventing kitchenware articles sensitive to thermal shocks from breaking as a result of sudden cooling during washing in a dishwasher (1), the method comprising the steps oft i) performing a first washing step by spraying a heated washing liquid against a first zone (21) that accommodates the articles which might break as a result of sudden cooling, the first zone (21), relative to the physical vertical, being located above a second zone (22) for accommodating kitchenware articles, the first and second zones (21, 22) being located inside a washing compartment (2) in the dishwasher; ii) performing a second washing step using a new washing liquid initially cooler than the washing liquid sprayed just before the end of the first washing step, the second washing step comprising: - a first operating sub-step of spraying the new washing liquid into the washing compartment (2) without alloving the new washing liquid to come into contact with the first washing zone (21); - a sub-step of heating the new washing liquid, this heating sub-step being at least partly simultaneous with the first operating sub-step; - a second operating sub-step, following the first operating sub-step, in which the new washing liquid strikes the first zone (21) of the washing compartment (2).
