Dish Washers
Dish Washers
How do dishwashers work?
Dish Washers have 5 main cycles.
The fill cycle
This cycle ironically typically starts by draining the standing water that the dishwasher keeps to protect the seals in its system.
The dishwasher then sends power to the solenoid in its water inlet valve to allow water to flow into the machine via your homes water pressure.
The Rinse Cycle
Either a timer or sensor will tell the control board the dishwasher is done with the fill cycle and the rinse cycle will begin.
The circulation motor will then be given power and your spray arms or water dispersion system will begin to run.
Most Washers begin heating water as soon as sufficient water is in the appliance.
Wash Cycle
Usually about 15 minutes into the cycle the soap dispenser will open causing the wash cycle to begin
This can be caused by heat and a wax motor , rotation of the spin arms, or a timer and solenoid.
Final Rinse Cycle
The soapy water is drained from the washing machine and fresh water is allowed to enter once more.
The circulation pump once more sends the water through the dispersion system.
Dry Cycle
If your washer has a heated dry cycle your heating element will warm up heating the air.
A vent may open due to a solenoid or wax motor if included in your model.
Often times, dishwashers will start their wash cycle by draining the standing water in the bottom of the dishwasher. The dishwasher will send power to the inlet valve and the homes water pressure will send water through the dishwashers inlet hose to it's tub.
Some Common problems
An inlet valve can experience various problems.
If you notice a puddle forming under your dishwasher it is usually from a leaky hose, bad connection or a door seal problem
