Winter is a great time to snuggle up in cosy blankets, make snowmen and sip hot cocoa – unless you have to deal with a damaged washing machine because of the frigid temperatures.

To avoid dealing with inconvenient and costly repairs, it’s important to winterize your washing machine before the cold sets in.

  • Before the winter season begins, take precautions, and winterize your washing machine. This will help to protect it from any potentially damaging freezing temperatures.
  • To prevent your washing machine from freezing in the future, you should always keep it away from cold drafts.
  • Close the water supply valve when you’re away from home for an extended time. If the temperature plummets during your absence, the water supply may be shut off, and your machine may be damaged.
  • Check your hoses and pipes regularly, and look for signs of wear and tear or leaks that could cause damage if not addressed.
  • Insulate your washing machine’s pipes, hoses, and other components to keep them from freezing during winter.
  • Consider draining your washing machine and filling it with RV non-toxic antifreeze if you expect extreme cold weather. This will help to protect the components from freezing and cracking.
  • Finally, make sure to check your owner’s manual for any specific instructions on how to winterize your washing machine.

In this article, we’ll cover how to best protect your washing machine from freezing temperatures so that you can enjoy an uninterrupted winter season.

Why Should You Winterize Your Washing Machine?

To prevent costly repairs, you should winterize your washing machine each year. Winterization is a process of protecting the internal components of your washing machine from freezing temperatures.

When the temperature drops below freezing, water lines and hoses can freeze up and burst, which could lead to flooding or other severe damage.

Additionally, freezing temperatures can cause the main components of your washing machine to crack or break, which could lead to costly repairs.

Note: If winterization is not taken seriously, it can cause leakage and void the warranty.
