How Dishwashers Work? Ask Solutions

Wondering about the ins and outs on how dishwashers work? A dishwasher is a robot that sponge & drench dirty dishes. Humans have to load the dishes, by adding detergent, setting the proper washing cycles, and turn it on, but the dishwasher fulfills a series of functions by itself. A dishwasher: 

  • Adds Water
  • Heats the water to the pertinent temperature
  • Instinctively opens the detergent dispenser at the right time
  • Drains the dirty water
  • Sprays more water on the dishes to rinse them
  • Drains the water from itself again
  • Warms the air to dry the dishes off, if the user has chosen that setting. 

Dishwashers monitor themselves to ensure that everything is running properly. A timer manages the length of each cycle. A sensor dredged the air & water temperature to prevent the dishwasher from damaging or overheating your dishes. One of the sensors can indicate if the level of water gets too high and activates the draining function to keep the drain washer from overflowing. When the water is enough, the dishwasher knows the dishes are clean.

More on how dishwashers work:

If you’re wondering how dishwashers work, dishwashers are watertight, they do not actually fill up with water. A small basin at the bottom fills up. Heating elements heat the water from 130 to 140 degrees Fahrenheit. A pump thrust the water up to the water jets, where it is sprayed & forced out against the dirty dishes. When the rinsing & washing is finished, the water evacuates down to the basin again, where the pump thrust the water out of the dishwasher. It depends on the type of dishwasher, the drain water may go right into the pipes under your sink. 

Intake Value: 

This is where the water comes from the home water supply enters the dishwasher. The unit pump does not pump the water into the basin when the intake nozzle opens, the pressure of water drives the water into the unit. 



An electric motor is an integral part of how dishwashers work, it powers the pump. The pump forces the water into the spray arms during the water cycle. The pump forces the water into the drain hose during the drain cycle. The motor-pump gathering is mounted underneath the basin, in the center of the dishwasher. There are two types of pump: 

  1. Reversible: The pump switches between pumping water to the spray arms & pumping water to the drain by repudiating the direction of the motor. Usually, the reversible pump is vertically mounted. 
  2. Direct Drive: The motor runs in the same direction, so the flow of direction is switched from the spray arms to the drain by a solenoid that closes & opens the suitable switches or valves, one can choose the connection from one to another. Usually, non- reversible pumps are horizontally mounted. 

Dishwashers can be installed in a portable or permanent configuration depending on how dishwashers work, the one you’re considering using. Portable units have finished sides and top that can be used as a countertop.
