Abstract

A method for rinsing crockery in a dishwashing machine is disclosed. The dishwashing machine includes a circulation pump, a water heater, an upper spray arm and a lower spray arm both alternatively fed by the circulation pump. The method includes the step of heating of the rinsing circulated water up to a maximum predetermined value. The method further includes the step of interrupting the feeding of the lower spray arm when a threshold water temperature is reached so that only the upper spray arm is fed by the circulated water.
