The present invention relates to a method for washing and disinfecting objects in awasher-disinfector comprising at least one chamber. The method comprises the steps of washing the objects in the chamber by circulating water and detergent in the chamber, rinsing the objects in the chamber by spraying non-circulating pressurized water in the chamber, draining the chamber, and disinfecting the objects. The steps of rinsing the objects and draining the chamber are performed at least partially simultaneously. The present invention allows for reduced water and energy consumption compared to prior art, while at the same time decreasing the risk for transfer of process residuals compared to when no rinsing is performed.
