Storing a washing machine in an unheated garage or outbuilding is a common question for homeowners looking to optimize space. The short answer is yes, you can store a washing machine in the cold, but it requires careful preparation to prevent damage. Unlike items stored in a climate-controlled environment, appliances exposed to fluctuating temperatures and moisture face specific risks that owners must address.
Understanding Cold Weather Risks
The primary concern with cold storage is the freezing of water within the machine. Modern washing machines rely on intricate plastic components, hoses, and pumps that are vulnerable to expansion and cracking when water turns to ice. Even a small amount of residual moisture can wreak havoc on internal mechanisms if the temperature drops below freezing for an extended period.
The Dangers of Moisture and Condensation
Cold environments often come with high humidity, which poses a different set of problems. Trapped moisture inside the drum, hoses, or the machine's electrical components can lead to rust and corrosion over time. Furthermore, condensation can form inside the circuits and motors, creating a environment that promotes metal degradation and could potentially cause short circuits when the appliance is eventually powered on.

Essential Preparation Steps
To successfully store a washing machine in the cold, you cannot simply unplug it and wheel it into the garage. A proactive approach is necessary to mitigate the risks associated with temperature and moisture. Taking the time to prepare the appliance correctly will extend its lifespan and ensure it functions properly when you need to use it again.
Cleaning and Drying
Before storage, run a maintenance wash with a specialized washing machine cleaner or a mixture of vinegar and baking soda. This eliminates any lingering detergent residue or mold that could become a problem in storage. Crucially, you must leave the door open for 24 to 48 hours to allow the interior tub, gasket, and hoses to dry completely. Any remaining water is a recipe for frost damage or mold growth.
Protecting the Appliance
Once the machine is dry, the next step is to shield it from the elements. While the washer is designed for indoor use, providing a barrier against direct exposure can make a significant difference in the condition of the appliance. Think of this step as insulating the machine against the harsh realities of the outdoor environment.

- Placement: Avoid placing the machine directly on a cold concrete floor. Use wooden planks or pallets to create an insulating layer.
- Covering: Use a breathable, waterproof cover to protect the exterior from dust, dirt, and precipitation. Avoid completely airtight plastic sheets, as these can trap humidity and cause condensation to build up inside the cover.
Long-Term Storage Considerations
If the washing machine will be stored for several months, additional precautions are necessary to protect the mechanical components. The goal is to ensure that the internal mechanisms remain lubricated and free from the pressure of trapped water.
| Action | Purpose |
|---|---|
| To prevent any water from entering the hoses and freezing | |
| To allow air circulation and prevent the gasket from sealing shut | |
| To avoid damage to the filter housing and ensure easy reinstallation |
Returning the Machine to Service
When the weather warms up or you are ready to use the appliance again, a careful restart procedure is essential. Do not immediately turn on the water or power. Inspecting the unit for any signs of damage, such as cracks in the plastic fittings or hoses, should be the first step. A visual check can prevent a potential flood caused by a compromised connection.
Once you have confirmed the physical integrity of the machine, you should run a short rinse cycle without clothes to flush the system. This helps to dislodge any particles that may have settled during storage and ensures that the water flow is functioning correctly. Only after these checks are complete should you resume regular laundry cycles.
