A Professional’s Guide: How To Store a Washing Machine

Over the years, I’ve helped countless people pack up their homes and place items into storage. Washing machines often cause trouble when you skip a few key steps. Leftover water can lead to rust or mould, and a neglected drum might give you a nasty surprise later on.

In this guide, I’ll show you how to store a washing machine so it stays clean, dry, and ready for action. Through hands-on experience, I’ve seen what works (and what doesn’t), and I’m here to make sure your washer remains in good shape for whenever you need it again. Let’s begin.

Reflecting on Real-Life Experiences

I’ve seen people finalise their entire house move, only to discover a soggy mess in the drum. One homeowner found a puddle under the machine after everything else was loaded onto the truck. Another client forgot to leave the door open while the machine sat in a dark garage, and within a few months, the rubber seal developed black spots due to poor air circulation.

Here’s what I’ve taken away from these moments:

• Leftover water can surprise you: Even a small amount can cause leaks or odd smells later on.

• A closed door invites mould: Damp, confined spaces are perfect for mildew to grow.

• A basic wipe-down makes a huge difference: Removing detergent and lint prevents buildup and foul odours.

• Proper storage is preventative: A few minutes of preparation now can save you time and money down the road.

• Avoid storing heavy objects on or near the machine: This prevents damage and maintains stability, ensuring optimal performance during storage.

Preparing the Washing Machine for Storage

I’ve seen many washing machines end up smelling stale or growing mould simply because they weren’t prepped correctly. A few basic steps go a long way. Here’s what I always recommend:

1. Clear Out All Water

• Drain completely: Run a quick cycle without clothes to empty any remaining water, then drain the hoses. A small amount of leftover water can lead to leaks or nasty odours, especially in colder spots. Draining the washing machine is particularly important if you are going to store it in an area with freezing temperatures.

• Dry the drum: After draining, leave the door open for at least an hour to let any moisture evaporate.

2. Give It a Thorough Clean

• Wipe everything down: Pay attention to the rubber seal, detergent drawer, and exterior surfaces. Residue left behind can cause bad smells over time.

• Check for hidden grime: A damp cloth and a mild cleaning solution usually do the trick. If there’s a stubborn spot, an old toothbrush helps.

• Run a hot water cycle: Add vinegar or bleach to the cycle to help eliminate detergent residue and dirt, ensuring the machine remains in optimal condition.

3. Remove and Secure Loose Parts

• Detach hoses and electrical wires: Wrap them in a towel or plastic bag to keep them dust-free and secure them with duct tape to prevent damage during transit.

• Lock or tape down moving parts: If your model has shipping bolts, put them back in place to protect the drum.

4. Prop the Door Slightly Open

• Prevent mould: Leaving the door ajar encourages airflow and stops moisture building up.

• Keep it propped: If it’s going into storage soon, a small wedge or cloth can keep the door from closing accidentally.

Selecting the Right Climate Controlled Storage Unit

Where you keep your washing machine can make or break your storage plan. Moisture, dust, and extreme temperatures can damage its inner parts or cause mould. To avoid these headaches, here are some tips:

• Pick a Dry, Clean Spot: A damp basement or leaky garage can lead to corrosion or mildew. If you can, choose a space with little to no humidity. Select a storage area that is dry, clean, and preferably climate-controlled to protect the washing machine.

• Go for Climate Control: If you have the option, a climate-controlled unit keeps the temperature consistent and reduces the risk of freezing. This is especially helpful if any residual water remains in the washer’s hoses or drum. A reliable storage facility often offers such units to ensure your appliances are well-protected.

• Consider Non-Climate Controlled Units: If you opt for a non-climate controlled unit, be aware of the risks due to temperature changes and humidity. Take extra precautions to protect your washing machine from adverse conditions.

• Elevate the Machine: Placing it on pallets or a sturdy stand helps in case of minor flooding or spills. A small platform also keeps the machine away from dust and dirt on the floor.

• Keep It Upright: Laying the washer on its side may harm internal parts, so store it in a normal standing position. This reduces the chances of damage while it’s not in use.

• Avoid Stacking Heavy Items on Top: Additional weight can dent the lid or knock parts out of alignment. Give your machine some breathing room instead.

Practical Do’s & Don’ts for Storage Success

Over the years, I’ve seen a fair few washing machines suffer avoidable damage—whether from being stored damp, tipped on their side, or buried under a stack of boxes. To help you avoid the same mistakes, here’s a clear list of do’s and don’ts based on what I’ve seen work best.

Do:

• Clean and dry your washing machine thoroughly before storing it to prevent mould, mildew, and smells.

• Disconnect water supply hoses and let them drain fully to avoid leaks or freezing in storage.

• Leave the door slightly open to allow airflow through the drum and stop moisture from building up.

• Wrap with a clean cloth or plastic sheet to protect the exterior from dust, scratches, and dirt.

• Use moisture-absorbing products like silica gel packets to help control humidity inside the unit.

• Store your washing machine upright to protect internal components and keep everything stable.

• Use protective covers to shield your appliance from moisture and environmental damage.

• Choose a climate-controlled storage unit to guard against extreme temperatures and dampness.

• Opt for secure storage facilities that offer proper environmental protection—and consider adding insurance for extra peace of mind.

• Check on your washing machine regularly for any signs of moisture, odours, or damage.

Don’t:

• Don’t place heavy items on top of the washing machine—this can dent the lid or knock parts out of place.

• Don’t store the machine on its side, as this can cause damage to the drum or motor.

• Don’t store it near chemicals or paint, which can damage surfaces or create unsafe conditions.

• Don’t ignore musty smells—they’re often the first sign of hidden moisture or mould.

• Don’t use self-storage units without climate control if you can avoid it. Fluctuating temperatures and humidity can cause long-term damage.

Additional Tips & Insights from My Experience

Over time, I’ve noticed a few extra steps that can really help keep a washer in good shape:

• Read the User Manual: It might feel obvious, but checking the manufacturer’s instructions often reveals handy advice for disassembly or moving. Each brand has its quirks, so a quick read can save trouble.

• Secure Cables and Hoses: I’ve lost count of how many times people have found kinked hoses or tangled wires. A few cable ties or rubber bands around hoses and cords prevent them from getting crushed or mislaid. Make sure to disconnect the water supply hoses and turn off the water valve shutoffs before performing any maintenance.

• Opt for a Climate-Controlled Self Storage Unit if You Can: Although it’s not essential, a stable temperature works wonders for large appliances. If you’re paying to store it anyway, a climate-controlled self storage unit with minimal humidity and a steady climate is well worth considering.

• Keep a Spare Cloth or Towel Inside: A small cloth in the drum helps absorb any drops of moisture that might sneak in. Just remember to replace it if it gets damp over time.

• Ask About Storage Insurance: If you’re using a professional service, ask about cover for appliances. Mishaps are rare, but a bit of added peace of mind can help you sleep better while your machine is out of sight.

All these steps boil down to one key lesson: a little care upfront keeps the washer running well for years to come. Whether it’s a small flat or a large family home, giving your machine the right treatment now means fewer headaches later.

Real-Life Case Study: A Family’s Washer Journey

Not long ago, I worked with a family moving from a small flat to a larger home. They had a reliable washing machine that they planned to keep in storage for a few months until their new place was ready. At first, they simply unplugged it and hoped for the best. However, when we arrived, I noticed two main concerns:

1. A Slight Musty Smell

   • The machine’s door had stayed shut for weeks, allowing dampness to linger.

   • We gave the drum a quick wipe-down with a cloth soaked in a mild cleaning solution.

2. Leftover Water in the Hoses

   • A tiny bit of water had pooled in the supply hose.

   • We drained it fully and allowed everything to air out.

Once these issues were sorted, the family followed the steps we’d discussed: draining the washer, wiping the seal, propping the door open, and storing it upright in a clean, dry unit. When the time came to move it into their new home, the washing machine was fresh and ready to go, with no nasty surprises.

This experience showed them (and me) how small efforts can make all the difference. A bit of draining and drying up front can keep your washing machine in top shape, even if it’s out of sight for months.

Quick-Fire Checklist: Storing a Washing Machine Safely

• Clean thoroughly: Wipe down the drum, seal, and drawers.

• Drain completely: Remove any leftover water from hoses or the drum.

• Prop the door open: Let air flow through to prevent mould.

• Wrap it up: A cloth or plastic sheet keeps dust and scratches away.

• Elevate off the ground: Protect against damp floors or minor floods. Elevating the washing machine off the ground can safeguard it against potential water damage.

• Keep it upright: Avoid damaging important internal parts.

• Check regularly: Look out for moisture, odours, or pests.

• Steer clear of heavy objects on top: Prevent dents or warped parts.

• Use silica gel if possible: Trap excess moisture inside or around the drum.

• Choose a dry, clean spot: Minimise the risk of rust or mould.

• Clean the lint trap: Regularly wash the lint trap in your dryer by removing it and soaking it in a warm soapy mixture to thoroughly eliminate any built-up lint.
