You’d think that a machine designed to clean things would stay clean itself.
Unfortunately, that’s not always the case.
One of the most common complaints we hear from homeowners is:
“My washing machine smells musty, but it looks clean.”
The good news? The cause is usually simple, and so is the solution.
Modern high-efficiency (HE) washing machines are designed to use less water and less energy than older machines. While that’s great for utility bills, it also means detergent and moisture can sometimes build up inside the washer.
One of the biggest contributors is using too much detergent.
Many people fill the detergent cup to the line, assuming more soap means cleaner clothes. In reality, excess detergent often doesn’t fully rinse away. Instead, it accumulates behind the rubber door seal, inside hoses, and between the inner and outer tubs.
Over time, that residue traps moisture and creates the perfect environment for mould, mildew, and unpleasant odours.
This is the biggest change most homeowners can make.
For most loads, 1–2 tablespoons of HE detergent is all that’s needed.
Using more detergent doesn’t make clothes cleaner; it simply leaves more residue behind.
After finishing a load, leave the washer door slightly open.
This allows moisture to escape and improves airflow inside the drum, helping prevent mould growth.
If your washer has a detergent dispenser drawer, leave that open as well.
The rubber gasket around the door is one of the most common places for moisture, lint, and detergent residue to collect.
Simply wipe it down with a clean cloth and check for debris hidden in the folds.
Most modern washers include a Tub Clean or Self Clean cycle.
Running this cycle once per month helps remove detergent buildup and keeps the interior of the machine fresh.
If your washer doesn’t have a dedicated cleaning cycle, run an empty load on the hottest and longest cycle available.
We always recommend using a reputable wash machine cleaner for optimal tub cleaning results.
Many front-load washers have a drain filter located behind a small access panel near the bottom of the machine.
Cleaning this filter periodically removes lint, hair, and debris that can contribute to odours and drainage issues.
Check your owner’s manual for instructions specific to your model.
Many homeowners use white vinegar to help control odours.
If you choose to use vinegar, it should only be added during an empty Tub Clean or Self Clean cycle.
For regular maintenance, we recommend using a washer cleaner specifically designed for high-efficiency washing machines.
Absolutely.
High-efficiency washers are engineered to work with low-sudsing detergents.
Regular detergent produces excessive foam, which can leave residue behind, reduce cleaning performance, and place additional strain on internal components.
Using the proper HE detergent and using the correct amount is one of the easiest ways to extend the life of your washer.
Most washer odours can be prevented with just a few minutes of maintenance each month.
Using less detergent, improving airflow, running cleaning cycles, and keeping filters clean will help your machine stay fresh, operate efficiently, and avoid costly repairs down the road.
If your washer continues to smell, leak, or isn’t cleaning properly, our team at Kelowna Refrigeration & Appliance Service is always happy to help.
When Should You Call a Professional?
While regular maintenance can solve many common washer odour issues, some problems require professional attention.
Consider calling a technician if:
In some cases, odours can be caused by clogged drain systems, failing pumps, damaged door gaskets, or buildup in areas of the machine that aren’t accessible without partial disassembly.f
Addressing these issues early can help prevent more expensive repairs down the road and keep your washer operating efficiently for years to come.
