How the dishwasher works?

A dishwasher is equivalent to a robot that cleans and rinses dirty dishes.
It has a timer that operates like a small computer, regulating length of each cycle. There are sensors to detect water and air temperature, water level and some that can detect the dirtiness of the water coming off from the dishes.

Compartments of a dishwasher:
Control mechanism
Located inside the door behind the control panel. Most are using simple electro-mechanical system, which works like timer. Modern units have computerized control system, door latch or child safety locks.


Intake valve
The main supply of water to the dishwasher. When the valve opens, water pressure drives the water into the unit without pumping in water.

Pump
An electric motor ontrols the pump is situated at the bottom of the basin, in the center of the dishwasher. During pump cycle, water forces up into the spray arms from the pump's pressure. During the drain cycle, the pump automatically directs water into the drain hose.

The magic of a dishwashers:
•Fills itself water and heats, it at appropriate temperature
•Opens detergent dispenser automatically
•Shoots water through jets to get the dishes clean
•Drains the dirty water and rinses dishes
•Optional to dry the dishes off

Inside Dishwasher
Watertight and not filled with water.
Small basin at the bottom fills up.
Maximum heating goes up to 130 to 140 degrees Fahrenheit.
A pump will propels water to the water jets spraying against the dirty dishes. Drying the dishes is an optional cycle.

Needless to say, common problems occur from dishwashers includes getting he dishes squeaky clean, stuck-on food or detergent, low water pressures due performance of water intake valve or minerals in the waters that will clog up the jets.

But to think of it, we don't have to stand all night cleaning the party plates from last night's barbeque. Isn't that nice?

This is four Guideline to using a Dishwasher:
Don't use regular dish soap. Use only those designed for dishwasher.

Don't overload the dishwasher. Space needed for water jets to spray onto the dishes.

Don't mix steel and silver items to avoid corrosion.

Don't put wood, cast iron; fine china, crystal or hand-painted dishes into the dishwasher.
