Abstract:
A dishwasher having a washing chamber with upper and lower dishracks disposed therein and having associated therewith upper and lower spray devices supplied with washing liquid respectively by first and second pumping devices. The first and second pumping devices are commonly mounted in a sump of the washing chamber and driven by a single unidirectional motor. The pumping devices are positioned in axial relation to one another with the lower or first pumping device supplying washing liquid at a lesser pressure to the upper spray device and the upper or second pumping device supplying washing liquid at a higher pressure to the lower spray device. A water level control is provided to supply the washing chamber with first and second levels of washing liquid with the lower pumping device supplying washing liquid to its associated spray device at both the first and second levels of washing liquid and the upper pumping device supplying washing liquid to its associated spray device only when the second level of washing liquid is present in the washing chamber. The lower pumping device supplies washing liquid alternatively to the upper spray device or to a drain conduit.
