Luckily, not everything is ever really dirty, but you still want the whole lot clean. Now you can have less than a full load in your dishwasher and choose which rack you want washed with ZoneWash. If you select the top sprinkler, only the top rack(s) will be washed. Choosing the bottom sprinkler will only wash everything in the bottom rack. If you still want to wash a partial load of dishes with both sprinklers selected, they will run alternately. This provides tangible energy and money savings. Full performance at partial loads.
The end of the washing cycle is acoustically signalled.
