ABSTRACT:
A dishwashing apparatus having a pump arrangement which is belt driven by a laterally disposed drive motor. The apparatus further includes a tub defining a washing chamber and a fluid inlet system including a fill valve for supplying fluid to the washing chamber. The pump recirculates the fluid within the washing chamber to wash the dishes and drains the fluid from the washing chamber. A timer controls the apparatus through a predetermined cycle of recirculation and drain periods for rinsing and washing the dishes. Operation of the fill valve is controlled to provide different levels of fluid for rinsing and washing with the fill valve being operable prior to recirculation in predetermined fills to provide a first fluid level and being operable after recirculation has begun in at least one other fill to provide a second higher fluid level.
