With only .83 gallons of water, filtration is the start of improved performance. Water is cleaned through

the fine and ultra-fine filters before it enters the main pump. Water must also flow through the Piranha

Hard-Food Disposal and finally into the wash pump assembly. Clean filtered water then flows into

the diverter system which directs it to either the lower spray arm or mid spray arm and upper sprayer.

Water is jetted through more jets and with more power due to different wash zones created by the

diverter.

This section will discuss wash system filtration, operation, components, removal procedures and

diagnostics. The new 2020 plastic tub dishwasher features alternating spray arms allowing low water

use, helping energy efficiency. A diverter system is used to isolate the wash arms and is controlled

by cycling the wash pump as described later in this section. Some models have a wash zone feature

which allows the consumer the flexibility of washing in the lower or upper racks only. Using this feature

will shorten the cycle time by 30%. When Bottle Wash is selected, the upper rack time is increased

allowing the bottle wash feature to be used for maximum cleaning. Filtration has been greatly improved

to allow clean filtered water to circulate during wash. The fine and ultra-fine filters are consumer

removable and cleanable.
