Abstract: A dishwasher has a container with baskets for the articles to be washed, a flushing system with a scavenging pump, spray arms, a strainer system with a fine strainer and a coarse strainer, and a discharge pump. The operation of the dishwasher is controlled by a control system which, after a prewashing controls partial drainage of the water to such an extent that the water level is lower than the upper surface of the fine strainer. With this reduced water level, the fine strainer is cleaned by running the residual amount of water through the flushing system during a predetermined time interval. Dirt flushed away from the strainer surface is collected in the central part of the strainer system and is discharged after completion of the flushing together with the residual water amount.

Abstract: To secure a desired value, preferably adjustable in advance, of the moisture content at the end of the drying process, independent of the amount of articles to be dried and of the material of these articles, a tumbler dryer may be provided with a temperature sensor (G) which senses the temperature (T) of the exhaust air from the drum (TR). The tumbler dryer is provided with control members (S) which determine the value of the temperature at the time when the rate of increase of the temperature during the latter stage of the drying process starts increasing, and which terminates the supply of hot air to the drum when the temperature has risen by a preset amount, corresponding to the desired moisture content, above said value.
