Washing machine maintenance: descaling, filters and small habits
· 4 min read
Run an empty hot cycle with machine cleaner or plain white vinegar every month or two, wipe the door gasket and leave the door ajar to dry between washes, and clean the drain-pump filter a couple of times a year. Those three habits prevent most washing machine smells and a fair share of the breakdowns.
Washing machines fail slowly — a smell here, a longer cycle there — until a pump or bearing goes. A little routine care avoids most of it.
Every month or two
The monthly jobs are all about residue. Detergent and softener build up in the places a 30-degree wash never really reaches, and that build-up is what turns into the smell.
- Run an empty hot cycle with a machine cleaner or plain white vinegar to clear detergent residue and odour.
- Wipe the door gasket (front-loaders) and leave the door ajar to dry — this is where mould and smell start.
- Clean the detergent drawer.
A couple of times a year
These are the ones that prevent an actual failure rather than a smell. The drain-pump filter is the most useful five minutes you can spend on a front-loader.
- Clean the drain-pump filter (front-loaders): it catches coins, lint and hair, and a blocked one stops the machine draining.
- Check the inlet-hose filter mesh for grit, especially in hard-water areas.
- Look at the hoses for bulges or cracks — a burst inlet hose can flood a room.
Good habits
Mostly a matter of not asking the machine to do more than it was built for. Overdosing detergent and overloading are the two most common mistakes, and both cost nothing to stop.
- Use the right amount of detergent — more is not better and leaves residue.
- Don't overload; it strains the bearings and washes badly.
- In hard water, an occasional descaling cycle keeps the heating element efficient.
Record the purchase date and any repairs. When a machine that's been reliable for eight years starts needing frequent fixes, the history tells you it's a replacement decision, not another repair.
Common questions
Why does my washing machine smell?
Detergent residue and a damp door seal, in that order. Front-loaders are worse for it because the rubber gasket traps water and detergent film after every wash, and washing mostly at low temperatures never gets hot enough to clear it. Run an empty hot cycle with machine cleaner, wipe the seal dry, and leave the door ajar between washes.
How often should you clean a washing machine?
An empty hot maintenance wash every month or two, and the drain-pump filter a couple of times a year. Wiping the door seal and leaving the door open is a per-wash habit rather than a scheduled job, and it does more against smell than either of the others.
Can I use vinegar to clean a washing machine?
Yes, plain white vinegar on an empty hot cycle clears residue and odour perfectly well, and it is cheaper than a proprietary cleaner. Never run it in the same cycle as bleach. Some manufacturers advise against using it often because of the effect on rubber seals and hoses, so if your manual says so, use a dedicated machine cleaner instead.
Does overloading damage a washing machine?
Over time, yes. An overloaded drum puts extra load on the bearings and suspension, and the clothes wash badly anyway because they need room to move through the water. It is one of the few maintenance problems that is free to fix, since the answer is simply to run two washes.
