How Hot Does a Whirlpool Dishwasher Get?

Have you ever wondered about the temperature inside your dishwasher and what it means for your dishes?

Many homeowners struggle with understanding the temperature inside their Whirlpool dishwasher, which is crucial in determining cleaning efficiency and safety.

Specifically, a Whirlpool dishwasher typically reaches temperatures of 120 to 150 degrees °F (49 to 65 degrees °C), ensuring optimal cleaning and sanitation.

Dive into this article to explore the intricacies of dishwasher temperatures, the science behind it, and how to make the most of your Whirlpool appliance for sparkling clean dishes.

Whirlpool dishwashers are a popular choice for many households due to their efficiency and reliability. Understanding the temperature settings of a Whirlpool dishwasher is crucial for achieving optimal cleaning results and ensuring the safety of your dishes.

What is a Whirlpool Dishwasher?

Whirlpool dishwasher is known for its high-pressure spraying feature. With 21 nozzles, this feature cleans every inch of the interior tub. This means your dishes will be sanitized. 

Many manufacturers don’t bother with this feature, so Whirlpool has made it one of their best-selling features. You can buy this dishwasher in either white or fingerprint-resistant stainless steel.

Whirlpool dishwashers come with plastic or stainless steel tubs. They don’t need stainless tubs if they have heating elements on the bottom. Whirlpool is also known for making quiet dishwashers, but theirs aren’t the quietest on the market. 

While the Legacy Whirlpool dishwashers are inexpensive, they’re loud and look out of place in a modern kitchen. 

How Hot Does a Whirlpool Dishwasher Get?

Most dishwashers, including Whirlpool, use hot water to clean dishes, typically between 130-140 °F. This temperature range is hot enough to kill bacteria and remove most food residue.

However, some dishwashers, including Whirlpool models, have cycles reaching temperatures up to 190 °F. These higher temperatures are beneficial for cleaning heavily soiled dishes or for sanitizing dishes. It is important to note that the average dishwasher temperature is sufficient for everyday cleaning needs.

If your dishwasher doesn’t get hot enough, it’s probably a malfunction in the heating element or a buildup of deposits and grease. Dishwashers use different heat settings to clean their dishes thoroughly.

Whirlpool’s High Temp Cycle

The High Temp Cycle on Whirlpool dishwashers is an excellent option for cleaning heavily soiled dishes or for sanitizing dishes. For example, they are designed to break down grease, starches, and sugars. The hotter the water, the more effective your Whirlpool dishwasher will be. 

This cycle heats the water to a minimum of 130 °F, which is hot enough to kill bacteria effectively. Additionally, the High Temp Cycle utilizes a longer wash time than other cycles, ensuring thorough cleaning of all dishes. The High Temp Cycle is ideal if you frequently deal with tough stains or want to ensure maximum hygiene.

If your Whirlpool dishwasher makes strange noises or does not drain completely, run the Diagnostics Cycle. This cycle, which begins when the door is closed, clears information about the last run and forces the next cycle to be a sensor calibration cycle. 

The diagnostics cycle typically takes between 10 and 20 minutes to run. After running the diagnostics cycle, the dishwasher should be back up and running.

How Do You Use a Whirlpool Dishwasher?

See how to use a whirlpool dishwasher below.

  • Step 1: Check the front panel and back for error codes. Usually, the dishwasher will have a sheet of paper with these codes printed on it. You can use this sheet to troubleshoot electrical problems and resolve them quickly. 
  • Step 2: Unplug the dishwasher from the power source and look at the error codes.
  • Step 3: Choose between two different sanitizing cycles. The sanitizing cycle is perfect for baby bottles, which can withstand high temperatures. The wash cycle itself is also different. 

The washing process uses high-temperature water to wash dishes and other kitchenware. The water goes through a heating chamber with small heat coils, which quickly heat the water to 161 °F. 

Other brands of dishwashers use heat elements to heat the water, so choosing this mode is a better option.

Factors Affecting Dishwasher Temperature

Built-in Water Heater

Some dishwashers, including specific Whirlpool models, have a built-in water heater. Whirlpool dishwashers often come with integrated water heaters responsible for raising the temperature during the washing cycle.

This feature allows the dishwasher to heat the water to a higher temperature than those relying on the hot water supply from the home. If your Whirlpool dishwasher has a built-in water heater, it can reach higher temperatures, providing enhanced cleaning performance.

Cycle Selection

The cycle you select on your Whirlpool dishwasher significantly affects the temperature of the water. For instance, the High Temp Cycle will heat the water to a higher temperature than the Normal Cycle. It is important to choose the appropriate cycle based on the level of the desired cleaning outcome.

Understanding the temperature variations between different cycles will help you optimize the cleaning efficiency of your Whirlpool dishwasher.

Water Supply Temperature

External factors like the initial water supply temperature can involve the cycle time and efficiency of the dishwasher. If the initial water supply is cold, the dishwasher must heat the water to increase the temperature until it reaches the desired temperature for effective cleaning.

It is essential to consider the water supply temperature when selecting the cycle on your Whirlpool dishwasher. Ensuring that the water in the dishwasher is at the right temperature is essential for optimal performance. This can be checked with an external thermostat or by pausing the cycle.

Importance of Dishwasher Temperature

Cleaning Efficiency

Temperature directly affects the cleaning efficiency and removal of leftover food and grease. The High Temp Cycle of Whirlpool dishwashers enhances the cleaning process by eliminating bacteria and ensuring thorough cleaning.

Understanding the implications of dishwasher temperature on cleaning efficiency will help you achieve spotless dishes every time.

Energy Consumption

Different temperature settings on your Whirlpool dishwasher can impact energy consumption. Higher temperature settings require more energy to heat the water. It will increase energy consumption but provide better cleaning.

Material Safety

Consideration of temperature effects on different materials like plastics within the dishwasher is essential to prevent damage. Higher temperatures can cause plastic items to warp or melt. Understanding the temperature effects on different materials will help you choose the appropriate cycle and temperature settings to ensure the longevity of your dishes and dishwasher.

Dishwasher Temperature Optimizing Tips

To select the temperature settings of your Whirlpool dishwasher, consider the following practical tips:

  • Select the appropriate cycle based on the level of soiling and desired cleaning outcome.
  • Take into account the temperature variations between different cycles.
  • Be mindful of the water supply temperature and its impact on the dishwasher’s temperature.
  • Strike a balance between temperature settings and energy efficiency to minimize energy consumption.


Whirlpool dishwasher is known for its high-pressure spraying feature. But despite its recognition as one of the best dishwashers in the market, you should familiarize yourself with how hot the whirlpool dishwasher gets. 

In conclusion, Whirlpool dishwashers offer a temperature range of 110-190 degrees, depending on the cycle. The High Temp Cycle, reaching a minimum of 130 °F, is particularly effective for cleaning heavily soiled dishes or sanitizing dishes. Factors such as water heater integration, cycle selection, and external factors like water supply temperature influence the dishwasher’s temperature.

Understanding the importance of dishwasher temperature on cleaning efficiency, energy consumption, and material safety is crucial for optimizing your Whirlpool dishwasher’s performance.
