How Does a Combination Washer and Dryer Work?

Posted on 11/20/2023

In today's fast-paced world, efficiency is key, even in household chores. The combination washer and dryer, a marvel of modern technology, has gained immense popularity for its dual functionality, allowing users to seamlessly transition from washing to drying without the need for separate appliances.

Understanding the Basics: Washer and Dryer Combos

Before we dive into the cycles and functionalities, let's understand the fundamental components of a combination washer and dryer. These multifaceted machines typically include a drum, a detergent dispenser, a water inlet, and an exhaust vent.

Washing Cycle

Just like a traditional washing machine, the washing cycle of a combination washer and dryer mirrors that of a traditional washing machine. Water is pumped into the drum along with detergent, creating a soapy mixture. The agitator or drum then rotates, ensuring thorough cleaning of dirty laundry.

Drying Cycle

Transitioning seamlessly from washing to drying, the drying cycle employs various methods, such as ventless drying or vented drying, depending on the unit. Heat and airflow collaborate to eliminate moisture, which is either pumped out or drained. The remaining warm air is then circulated back into the drum, effectively drying the clothes.


The beauty of combination washer and dryer units lies in their dual functionality. There is no need to transfer clothes between machines; these appliances seamlessly switch from washing to drying, streamlining your laundry routine and saving you time.

Vented vs Non-Vented Washer Dryer Combos

We mentioned that a combination washer and dryer can either be vented or non-vented when it comes to the drying process. If you're curious about the difference between the two drying methods, let's explore how both of these options function.

Vented Washer Dryer Combos

Before they begin drying, these models typically use a spin cycle to eliminate excess water. Then, they expel moisture through a venting system, usually requiring an external exhaust vent. This vent releases hot, humid air outside during the drying process, resembling the functionality of standard dryers.

Non-Vented Washer Dryer Combos

Non-vented units use a condensation drying process. Moisture is condensed into water, collected in a reservoir, and then pumped out or drained. This means they do not need an exhaust to dry clothing.

As the drum spins, it generates steam from the clothing. This moisture is then redirected through the condensing chamber, creating condensation that is subsequently drained, enabling the hot air to circulate once more.

For instance, the GE Profile Capacity UltraFast Combo Washer and Dryer uses ventless heat pump technology. It quickly dries large loads using less heat, so you can easily wash and dry large items, such as comforters, without the need to hang them to dry.


To help ensure you choose the right laundry appliance, consider your space, capacity needs, venting options, energy efficiency, programmable features, noise levels, and budget. Visiting a showroom can provide a hands-on experience, helping you visualize the unit in your space.

Advantages of Combination Washer and Dryer

Space Efficiency: One of the primary advantages of these appliances is their space efficiency. In smaller living spaces, such as apartments or closets, the combination unit eliminates the need for two separate machines, providing valuable floor space.

Time-Saving: The integration of washing and drying functions significantly reduces the overall laundry process time. Users can load their dirty clothes, start the cycle, and return to freshly washed and dried laundry without the hassle of transferring wet clothes between machines.

Energy Efficiency: Combination washers and dryers are designed with energy efficiency in mind. The ventless drying system consumes less energy compared to traditional dryers, contributing to lower utility bills and a reduced environmental footprint.

Common Misconceptions

Performance Concerns: Some users may worry about the effectiveness of the drying cycle. However, advancements in technology have addressed these concerns, providing efficient and reliable drying capabilities.

Laundry Quality: Combination units are designed to provide the same level of cleanliness and care as standalone washers. Users can expect their clothes to come out just as fresh and clean.

Longevity: Concerns about the lifespan of combination units are often unfounded. With proper maintenance, these appliances can last for many years, offering a reliable and space-saving laundry solution.
