Why does my front-load washer smell musty or mouldy?
Most common cause on a washing machine in the GTA: mould/biofilm growing in the door-gasket folds and dispenser from a door kept shut after washing. A typical repair runs $190–$340 all-in, including the $149.95 diagnostic, credited 100% toward your repair. No safety hazard; book if cleaning doesn't resolve it (often points to a torn gasket or drain issue). Book at convenience

Common Washing Machine problems & what we check
Tap any problem for the likely causes, what is safe to check yourself, and what it costs.
Bad odour or mould (front-load)
Bad odour or mould (front-load): A musty/mildew smell from the drum, with black or grey gunk in the folds of the rubber door gasket and around the detergent drawer.
Also described as: musty smell, mildew odour, mouldy washer, stinky washer, smells bad
Likely causes
- Mould/biofilm growing in the door-gasket folds and dispenser from a door kept shut after washing (Most common)
- Detergent and fabric-softener residue build-up feeding the biofilm (Common)
- Standing water in the gasket or a slow/partial drain leaving moisture behind (Common)
- Cold-water-only, high-efficiency, low-water washing that never gets hot enough to clear residue (Occasional)
✔ Safe to check yourself
- Wipe the door-gasket folds dry after each wash and leave the door (and detergent drawer) ajar between loads — the single best fix and prevention.
- Run a hot tub-clean / "Self Clean" cycle with a washer cleaner or plain bleach on an empty drum.
- Pull out and wash the detergent drawer; reduce detergent and softener dosing.
✖ Leave to a technician
- If the smell persists after cleaning, a torn gasket harbouring mould or a partial drain blockage needs a technician.
- Don't bleach a torn gasket and call it done — a torn boot also leaks and must be replaced.

Repair or replace your washing machine?
A simple rule of thumb: if the repair costs more than half the price of a comparable new unit and the appliance is near the end of its life, replacement may make more sense.
A washing machine typically lasts – and costs $1,100–$1,900 to replace — so most faults under about $450 are worth fixing. We'll always tell you honestly when a repair isn't worth your money.
Keep your washing machine running
Simple habits that prevent the most common the GTA repairs.
- Leave the door and detergent drawer open between washes and wipe the door gasket dry — the top prevention for front-load odour and mould.
- Clean the drain pump filter (front-loaders, behind the small bottom-front panel) every few months to prevent drain and spin faults.
- Use the correct amount of HE detergent — over-dosing causes excess suds that clog the pump and leave residue.
- Keep the machine level on all four feet and balance loads so the tub doesn't bang and wear the shocks/suspension on spin.
- Inspect the fill hoses for bulges or cracks and replace rubber hoses about every 5 years (braided-steel hoses last longer).
- Run a hot tub-clean cycle monthly to clear detergent residue and biofilm before it smells.
