Circulation System
With only 0.75 to 0.95 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. Water is jetted
through more jets and with more power due to different wash zones created by the diverter.
The new 2021 Plastic Tub Value Model 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. 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.
