Dishwashers have become an essential appliance in many households, making the task of cleaning dishes more efficient and less time-consuming.
One of the key processes in a dishwasher’s cycle is draining the water at specific intervals.
This process ensures that dirty water is removed and replaced with clean water, which is crucial for achieving spotless and sanitary dishes.
How Many Times Does a Dishwasher Drain During a Cycle?
The number of times a dishwasher drains during a cycle can vary depending on the specific model and the chosen wash cycle.
Different dishwasher cycles use varying temperatures, times, and energy levels to cater to the needs of your dishes.
Some dishwashers have multiple stages in a single cycle, each requiring a draining and refilling process to ensure thorough cleaning.
For example, a standard dishwasher cycle may consist of the following stages: pre-wash, wash, rinse, and dry.
In this cycle, the dishwasher would drain at least twice – once after the pre-wash and then again after the wash stage – before proceeding to the rinse and dry stages.
However, keep in mind that some cycles, such as those designed for heavily soiled dishes, may require additional draining and rinsing steps to achieve optimal results.
Understanding the Dishwasher Cycle
The dishwasher cycle is the process that your dishwasher goes through to clean your dishes.
It typically consists of several steps, including filling the dishwasher with water, spraying the dishes with water and detergent, rinsing the dishes, and draining the water.
Understanding how your dishwasher cycles work can help you get the best results from your appliance and ensure that your dishes come out clean and dry every time.
When you start a dishwasher cycle, it begins by running a discharge pump to empty any remaining liquid inside the machine.
This step prevents water from previous cycles from mixing with the clean water used in the current cycle.
Next, hot water enters the machine, filling a reservoir at the bottom until it activates afloat.
In some dishwasher cycles, an electrical element heats the water to sanitize dishes further.
Once the reservoir is filled, a pump sprays water and soap onto the dishes, effectively removing food particles and grime.
During this process, the dishwasher may use different water pressure or spray patterns, depending on the specific cycle you have selected.
For example, a Normal Cycle is suitable for everyday dishes without heavy soil, while a Quick Wash Cycle can be used when you need to clean lightly soiled dishes in less time.
After the washing phase, the dishwasher then drains the dirty water and proceeds to rinse the dishes.
The machine refills with clean water, spraying it over the dishes to remove any leftover detergent and grime.
This rinsing process ensures that your dishes come out sparkling clean and free of soap residue.
Throughout a typical dishwasher cycle, the appliance will drain the water three to four times, depending on the model and the length of the cycle.
The first drain occurs right after you press the start button, and the subsequent drains happen after the washing and rinsing stages.
These draining steps help prevent water from becoming too dirty and ensure that your dishes receive the best possible cleaning.
Typical Stages of A Dishwasher Cycle
Here is the full cycle of a dishwasher from the initial filling to the drying stage.
At the beginning of a dishwasher cycle, a discharge pump empties any remaining liquid inside the machine.
Then, hot water enters the dishwasher from the side and fills a reservoir at the bottom. The water level rises until it activates a float.
In certain dishwasher cycles, an electrical element can heat the water to a suitable temperature for sanitizing dishes.
The prewash cycle is a short cleaning phase that uses cold or tepid water to remove loose food particles and grease from the dishes.
This stage helps to prepare the dishes for the main wash cycle, where heavier soiling is removed.
During the prewash cycle, water and soap are pumped through the spray arms, providing a gentle rinsing before the main wash.
Main Wash Cycle
During the main wash cycle, the dishwasher uses hot water and detergent to clean the dishes thoroughly.
The water is heated to a higher temperature than in the prewash cycle, typically around 120-150°F (49-66°C).
This allows the detergent to dissolve and effectively remove tough food particles, stains, and grease.
The main wash cycle also involves several rounds of spraying, rinsing, and draining to achieve optimal cleaning results.
The rinse cycle comes after the main wash, and it aims to remove any remaining detergent or food particles from the dishes.
During this stage, clean hot water is pumped through the spray arms to ensure that all soap residues are washed away.
In some dishwashers, a rinse aid is used to improve the water’s ability to remove residues and prevent water spots on the dishes.
The rinse cycle typically includes multiple rounds of spraying, draining, and refilling the water to ensure a thorough rinsing process.
The final stage of the dishwasher cycle is the drying stage.
There are two common methods for drying dishes in a dishwasher: heated drying and air drying.
Heated drying involves using an electrical element to heat the air inside the dishwasher and evaporate the remaining moisture on the dishes.
In contrast, air drying involves circulating the air or automatically opening the dishwasher door at the end of the cycle to allow steam to escape, and the dishes dry naturally.
Both methods ensure that your dishes are dry and ready to be put away once the cycle is complete.

The Draining Process in a Dishwasher
Here’s how a dishwasher drains after every process.
Draining after Prewash
The draining process in a dishwasher is crucial for removing dirty water and ensuring your dishes come out clean.
The first draining stage occurs during the prewash.
When you start a dishwasher cycle, it begins by filling up its water tank with water from your home’s plumbing.
As the water enters the dishwasher, any leftover water from previous loads gets pushed out through the dishwasher drain.
During this stage, the dishwasher loosens food particles and helps to rinse off initial dirt from your dishes.
Draining after Main Wash
After the prewash stage, the dishwasher moves on to the main wash cycle.
During this stage, the dishwasher uses hot water and detergent to thoroughly clean your dishes because it will need to handle more challenging stains like grease and baked-on food.
The dishwasher sprays water mixed with detergent at high pressure onto your dishes, ensuring a thorough clean.
Once the main wash cycle is complete, the dishwasher drains the soapy, dirty water through its drain, allowing for a freshwater supply for the next stage.
Draining after Rinse
The final draining stage occurs during the rinse cycle.
The purpose of the rinse cycle is to remove any remaining soap residue or leftover food particles from your dishes, ensuring they are completely clean and spot-free.
During this stage, the dishwasher uses clean water to rinse off your dishes.
Once the rinse cycle is complete, the dishwasher drains the remaining water through its drain, effectively finishing the cleaning process.
Throughout a typical dishwasher cycle, the appliance drains the dirty water three to four times.
This frequent draining ensures that your dishes are effectively cleaned and that any leftover dirty water is removed from the dishwasher.
By understanding the dishwasher draining process, you can better appreciate how your appliance works to keep your dishes sparkling clean.
