Why your washer smells before Thanksgiving—and how to fix it in one cycle

September in Metro Vancouver brings cooler mornings, falling leaves, and something else: a noticeable uptick in washing machine odour complaints. If your washer has started to smell like damp basement, you're not alone—and it's not a sign of failure. It's just autumn in the Lower Mainland meeting the realities of how your machine works.

Why autumn triggers washer odour

Your washing machine isn't actually dirty; it's *wet*. Moisture trapped inside the drum, especially in the rubber gasket around the door, creates an ideal environment for bacteria and mould to thrive. Summer in Richmond is dry enough that this happens slowly. But September through November? The humidity climbs, your family's wet jackets and damp towels go straight into the machine, and the drum never fully dries between cycles. That's when odour appears.

Front-load washers are particularly prone to this because water naturally pools in the seal. Top-loaders have it easier, but they're not immune.

The one-cycle fix

You don't need a repair call or a new machine. Run a cleaning cycle using one of these two methods:

**Vinegar method:** Pour 2 cups of white vinegar into the detergent dispenser (or directly into the drum for top-loaders). Select the hottest water setting and run a full wash cycle with no clothes inside. Vinegar dissolves buildup, kills odour-causing bacteria, and costs about 50 cents.

**Commercial cleaner:** If vinegar doesn't appeal, products like Affresh or Tide Washing Machine Cleaner are designed specifically for this job. Follow the package instructions—most work the same way as vinegar.

Run this cycle once, and the smell vanishes. Do it monthly from now through March, and you'll never notice it again.

The habit that prevents it

After every load, especially during autumn and winter, leave your washer door open. Prop it open for at least an hour—longer if you can. This lets air circulate through the drum and gasket, evaporating moisture before bacteria can establish itself.

It feels counterintuitive in a wet climate, but it works. The small amount of air movement makes all the difference.

Why now matters for Thanksgiving

In 17 days, your home will be full of guests, and laundry will pile up. Towels, napkins, tablecloths, and cleanup rags will run constantly. If your machine already smells, heavy use will amplify it—and your guests will notice. Running a cleaning cycle this week takes 45 minutes and solves the problem before the rush begins.

It's one of the simplest pre-holiday maintenance tasks, and it costs almost nothing.
