How a Dishwasher Works

Hot h2o travels to the interior of a dishwasher through a supply hose that connects to a water supply valve, typically mounted under the sink. To shut off the water to the dishwasher, you shut this valve. The other end of the supply hose connects to a h2o inlet valve inside the dishwasher. The inlet valve, electronically connected to the controls, opens and closes to supply water to spinning spray arms. These spray artillery, normally at both the top and bottom of the tub, are similar a high-pressure sprinkler system that sprays the dishes clean.
Dirty water collects at the base of the interior chamber, moves through a filter, and gets pumped back through the system during the early wash cycles. When all of the cleaning and rinsing cycles finish, the pump sends the dirty water out through a drainpipe. Then an electric heating element heats up to dry the dishes.
