A technician works through the drain pump and its filter, the drain hose, the lid or door lock, the suspension, the belt or motor, the inlet valves and the controls, and reads any error code the machine has stored. Many visits also involve what surrounds the washer: the supply hoses, the shut-off valves, the drain standpipe and the floor underneath.
Below: what each symptom usually means, supply hose care, front-load odours, levelling, leak protection and when a washer is worth fixing.
Washer won't drain, won't spin, leaks or shakes: likely causes
Many front-loaders have a pump filter behind a small panel at the bottom front, and the owner's manual explains how to clean it. Have towels and a shallow pan ready, because water pours out when it's opened. If the filter is clear and the problem remains, note the symptom and any error code before you call.
- Water left in the drum: a clogged pump filter, a sock or coin lodged in the pump, a kinked or blocked drain hose, or a pump that has failed.
- Clothes still dripping after the cycle: the washer may not reach full spin because the load is off balance, the drain is slow, the lid or door lock isn't engaging, or a belt, motor coupling or speed sensor has worn out.
- Water on the floor while filling points to a supply hose or its connection; while draining, to the drain hose or an overflowing standpipe; during the wash, to a torn door gasket or a leak at the tub or pump.
- Heavy shaking or walking: an unbalanced load, feet out of level, tired suspension springs or dampers, or, on a new machine, shipping bolts that were never removed.
- A rumble or grinding that grows louder at high spin often means worn tub bearings, a large enough job to weigh against replacement.
Washing machine supply hoses: inspection, replacement and shut-off valves
The two hoses that feed a washer stay under water pressure whenever the valves are open, even when the machine is off. A burst or leaking supply hose is a common cause of laundry-room water damage, and it tends to happen when nobody is home to notice.
- Ease the washer forward now and then and look at both hoses: bulges, cracks, kinks, rust or mineral crust at the fittings, or a damp floor are all reasons to replace them.
- Replace hoses as the washer or hose manufacturer recommends, and consider reinforced braided hoses, which are sturdier than plain rubber but still need regular checks.
- Use new rubber washers with new hoses and tighten the fittings as the instructions say; overtightening can crack a fitting.
- Leave enough space behind the machine that the hoses don't fold against the wall.
- Keep the shut-off valves reachable, and close them before a trip or a long weekend away.
- A valve that is seized, drips or won't close fully should be replaced by a plumber.
Front-load washer odour, mould and door gasket care
Front-loaders seal tightly and use little water, so moisture and detergent residue linger in the door gasket, the dispenser and the pump area. That's where the musty smell and dark spots come from, and most of it is prevented by habit rather than parts.
- Use detergent made for high-efficiency washers, in the amount the manual recommends; extra detergent leaves the residue that feeds odours.
- Wipe the gasket and the inside of the door after the day's last load, and check the folds for hair, lint and small objects.
- Leave the door and the dispenser drawer slightly open between loads so the drum can dry.
- Run the machine's cleaning cycle, or the cleaning routine the manual describes, on the schedule it gives.
- Take wet laundry out promptly instead of leaving it in the closed drum.
- A torn gasket, or one with stains that won't wipe off, can be replaced by a technician, and a smell that survives cleaning may come from the pump filter or a slow standpipe.
How to level a washing machine and stop it walking
Levelling is one of the simplest cures for a noisy, wandering washer, and one of the steps most often rushed at installation.
- Rock the machine corner to corner: all four feet should bear weight, and any rocking means a foot needs adjusting.
- Set a level across the top, side to side and front to back, adjust the feet, then tighten their lock nuts so they don't creep.
- On a newly installed machine, confirm the shipping bolts at the back came out, as the installation instructions require.
- Pedestals and stacking kits should be the ones designed for the model and fastened as instructed.
- Anti-vibration pads can soften noise but won't fix a machine that isn't level.
- If a springy wood floor carries the spin through the whole house, have a contractor look at the floor rather than replacing washer parts.
Washer leaking: what to do right away, plus drain pans and leak sensors
If water is spreading from the washer, stay out of standing water near the machine and its outlet. If you can reach the plug or the breaker without stepping in water, cut the power, then close both supply valves. Only pull the machine out and mop once the power is off, and don't run it again until the source of the leak is found.
A few devices limit the damage next time. They're especially worth considering for a second-floor laundry room, a finished basement or a condo, where a leak reaches someone else's ceiling.
- A drain pan under the washer catches drips and small leaks, and does far more good when it's piped to a floor drain.
- Battery-powered leak sensors on the floor sound an alarm, and connected models send an alert to your phone.
- An automatic shut-off valve closes the water supply when a sensor detects a leak; installing it on the plumbing is a plumber's job.
- Plug the washer into a grounded outlet: Health Canada warns never to remove a plug's third prong or use a three-to-two-prong adapter, since the ground prong reduces the risk of shock.
- Ask your insurer or condo corporation whether they require or recommend any of these devices.
Repair or replace a washing machine: which faults justify the fix
Drain pumps, lid and door locks, inlet valves, belts, door gaskets, suspension parts and hoses are routine repairs, and on a sound machine they're usually worth doing. Worn tub bearings, a cracked outer tub, a failed transmission or a corroded frame are bigger jobs, often close to the effort of a new machine. A control board is somewhere in between: the part may be easy to replace or hard to find, depending on the model.
Think about the machine as a whole: how it has run lately, whether it belongs to a stacked or matched pair, and whether a new one would fit the space and the floor. If you replace it, compare the EnerGuide labels of the models you're considering.
Washer Repair: frequently asked questions
Why does my front-load washer smell musty?
Moisture and detergent residue collect in the door gasket, the dispenser and the pump filter. Use high-efficiency detergent in the recommended amount, wipe the gasket, leave the door ajar and run the cleaning cycle. If the smell persists, have the pump filter and drain checked.
How often should washing machine hoses be replaced?
No single interval applies to every hose. Follow the washer and hose manufacturers' recommendations, and replace a hose sooner if it bulges, cracks, kinks or shows corrosion at the fittings. Inspect them whenever the machine is moved or serviced.
Why won't my washer door unlock?
Most washers keep the door locked while there's water in the drum or the cycle isn't finished. Run a drain and spin cycle; if the door still won't open, the drain or the lock itself may have failed. Don't force it, since that can break the latch.
Can I keep using a washer that leaks a little?
It's best not to. Small leaks tend to get worse and can soak the subfloor unseen. Close the supply valves when it isn't running and book a repair.
Who connects a new washer to the water and the drain?
Hooking a washer to existing valves and a standpipe follows the installation instructions. New or relocated valves, drain lines or standpipes are a plumber's job, and a new outlet or circuit is an electrician's.
