Dishwashers pretty much all work the same way. In order to understand how they work, there are three areas that you need to understand: The pump and motor system; The solenoids, valves, switches, and controls, and; The interior. Since dishwashers can be so complicated it is often best to leave repairing them to trained technicians unless you understand them completely.
The Pump and Motor system
All dishwashers have at least one motor. The dishwasher motor is attached to a pump which pumps water into the sprayer arms. The pump also pushes the water out and down into the drain during the drain cycle. There are a few dishwashers that are made in Europe that have 2 motors which are separate. One is used for draining and one is used for spraying.
The dishwasher motor is located underneath the dishwasher immediately behind an access panel. There are some models that have motors that are reversible and others don’t. Dishwasher motors that are reversible are mounted vertically in the bottom center of the dishwasher and the motor shaft will usually be pointed up. The pump is usually mounted on top of the motor and then attached underneath the dishwasher. When the motor runs one way, it drains the water, when it runs the other way, it pumps water up to the spray arms.
The motor is mounted horizontally and the motor shaft will usually be pointed sideways, near the bottom center of the dishwasher if the dishwasher’s motor only rotates in one direction. The dishwasher pump is mounted on the end of the motor underneath the dishwasher. It pumps water to the spray arms when the motor is running. To pump the water to the drain, a mechanical arm that is integrated into the pump and when the motor activates, it diverts the water to the drain.
The Solenoids, Valves, Switches, and Controls
All dishwashers have a minimum of 3, but will often have 6 or more solenoids, valves, switches, and controls. These include; The Timer; The selector switch; The water inlet valve; The float switch; The soap dispenser; The rinse aid dispenser; The drain solenoid; The thermostat; The door switch; The drying fan, and; The heating element.
Whirlpool Dishwashers have a timer that is located behind the main control panel either behind the lower access panel or at the front top of the dishwasher. The timer is either completely electronic that has a digital readout or it is mechanical device similar to a clock. The timer runs the dishwasher in a predetermined pattern. The timer provides the electricity to all of the dishwasher components at the proper time, for the proper length of time.
The Selector switch
Dishwashers typically have a minimum of 1 selector switch that is usually located on the primary control panel which is at the top front of the door. These switches allow for the selection of drying cycles, wash cycles, and the wash and rinse temperature. The timer depends on the switches to tell it which cycle options it needs to engage.
The Water Inlet Valve
The water inlet valve is located on the bottom left or right of the dishwasher behind the access panel on the bottom. The water inlet valve permits the water to flow into the dishwasher during the wash cycle. Normally, it is attached to the supply line for hot water, and also to a tube that is then attached to the right or left side of the dishwasher. The valve opens and lets water into the dishwasher when the timer sends the proper signal to the valve. When the timer stops sending the proper signal to the valve the valve ceases water flow.
The Float Switch
The float switch is designed to keep the dishwashers from overfilling. The float switch is typically a small switch which is attached to a float. This float is located on the bottom left side on the inside the dishwasher. As the water in the dishwasher rises, the float rises. When the float reaches a height that is predetermined, a switch is activated by the float and the electricity is cut off to the water inlet valve.
The Soap Dispenser
The soap dispenser on a dishwasher is located on the inside of the dishwasher’s door. If the timer cycle requires the soap to be emptied into the dishwasher, the soap dispenser either mechanically opens the soap dish or it sends an electric signal to a bi metal switch which opens the soap dish.
The Rinse Aid Dispenser
If he dishwasher has a rinse aid dispenser it is located on the inside of the dishwasher’s door. If the timer cycle needs the rinse aid to be emptied into the dishwasher, it provides a signal to a solenoid switch, which in turn opens the dispenser and measures the rinse aid into the dishwasher.
The Drain Solenoid
On some dishwashers, there’s a drain solenoid that is activated by a timer that opens a drain valve to drain the wash water through a hose and out to the house’s waste water system.
Dishwashers usually contain have at least one cylindrical, small thermostats. These thermostats usually have at least 2 wires attached to them. They protect humans, the dishes, and the dishwasher by turning off the heating element that heats the air or the water in the dishwasher when the dishwasher has reached a predetermined temperature. The thermostat automatically resets whenever the temperature decreases to another level that has been predetermined.
The Soil Sensors
Later model dishwashers have soil sensors that are comprised of multiple components that continually monitor the wash water during the wash cycle. These sensors help the dishwasher to wash for the amount of time which is appropriate with how dirty the dishes are, rather than for a predetermined period. The sensor signals the timer to continue with the next cycle, when the water becomes clear enough.
The Door Switch
Dishwashers have an interlock door switch. If this switch is functioning properly, it will turn off the dishwasher if the door is opened.
The Drying Fan
Many dishwashers use a small fan to blow heated air into the dishwasher to help dry the dishes faster. If the dishwasher has a drying fan, it’s located in the right back corner underneath the dishwasher.
The Heating Element
All dishwashers have a minimum of 1 heating element. It is usually a black circular tube that is located under the lower spray arm at the bottom of the dishwasher. This element usually assists in drying the dishes or in heating the wash and rinse water to the proper temperature. Some dishwashers that have another heating element integrated with the drying fan that is used to warm the air blown into the dishwasher to help dry the dishes.
The dishes are placed in the interior of a dishwasher. The interior contains the water filter, the upper part of the pump assembly, the tower that sprays water on the dishes, the spray arms, and the dish racks.
