The end of a wash cycle always sounds the same: that tired little beep, a soft clunk, the drum sighing to a stop. You pull out the warm clothes, give everything a quick shake, and do what almost everyone does without thinking. You leave the washing machine door open “to air it out” and walk away.
An hour later the kitchen smells fresh, the laundry basket is finally empty, and the machine sits there with its mouth wide open like a sleepy dog. You feel oddly virtuous, as if you’ve done the right thing for once in this endless war against mildew.
Except a growing number of appliance experts are starting to say: not quite.
The small laundry habit that quietly backfires
Leaving the washing machine door open feels like common sense. You’ve probably heard it from your mum, a neighbour, or some cleaning influencer on TikTok: “Leave the door open so it doesn’t smell.” So we do it. Day after day, wash after wash, the door stays propped open between cycles like a permanent invitation.
On the surface, it looks harmless. Behind the plastic and metal, something else is going on – slowly, quietly, and quite expensively.
Ask any appliance repair technician what they see most in modern homes and a pattern appears. Hidden around the hinges and door seal, they often find warped rubber, stiffened plastic and tiny deposits of detergent that have dried like cement. One UK engineer told me he can walk into a house, glance at a constantly open machine door, and predict with eerie accuracy that the door gasket will need replacing in a year or two.
The irony? These are usually the very people who are proud of “taking care” of their appliance.
Experts say the issue isn’t the odd hour of airing. It’s the constant, long-term position of the door being left wide open, sometimes 24/7. That pulls on the hinges, keeps the rubber seal slightly twisted, and exposes delicate parts to dust and accidental bumps. Over time, this repeated strain can lead to misalignment, leaks, and that maddening rattle when the spin cycle kicks in. The open door also becomes a trap for humid air from the room, which condenses on cooler metal parts and feeds the same mould we thought we were preventing.
How to air your machine… without wrecking it
Most specialists now recommend a middle path: don’t slam the door shut on a wet drum, but don’t leave it hanging open like a wardrobe either. The ideal gesture is surprisingly simple. After a wash, pull out your clothes, gently wipe the rubber seal and glass with a small towel, then leave the door just slightly ajar – a few centimetres, no more.
This tiny gap lets air circulate while keeping the door supported in a natural position, rather than pulling on the hinge like a heavy open gate.

If this sounds fussy, you’re not alone. We’ve all been there, that moment when you swear you’ll “do things properly” and then life happens, kids shout, work emails ping, and the machine gets forgotten. *Laundry habits belong to that messy category of good intentions that rarely survive a busy week.*
Let’s be honest: nobody really does this every single day. Yet changing just one or two small actions – like wiping the seal twice a week and keeping the door only slightly open instead of fully extended – is often enough to avoid the most common issues.
“People think mildew is their main enemy,” says French appliance technician Laura Martin. “But what quietly kills machines is long-term stress on parts that were never designed to stay open at a full angle for years.”
- Open the door only a little: a hand’s width is plenty for airflow.
- Wipe the door seal regularly to remove trapped water and detergent.
- Leave the detergent drawer slightly open instead of the whole door.
- Run a hot maintenance wash once a month to flush out hidden residues.
- Check the hinge screws twice a year if your machine starts to sag or creak.
A small change that can save an expensive appliance
What makes this topic oddly fascinating is how invisible the damage can be. You don’t wake up one day to a snapped hinge out of nowhere. The machine starts to close less smoothly, you push a little harder, the rubber looks a bit tired, a faint musty smell returns even though the door is always open.
Then, one leak on the kitchen floor later, you’re suddenly talking about a repair bill that feels wildly out of proportion with such a tiny daily habit.
| Key point | Detail | Value for the reader |
|---|---|---|
| Door position matters | Leaving it fully open for days strains hinges and seals | Reduces risk of costly repairs and leaks |
| Controlled airflow is enough | A small gap plus wiping the seal beats a wide-open door | Keeps odours down without damaging the machine |
| Simple routine wins | Quick wipe, monthly hot cycle, slightly ajar door | Extends the life of the appliance and saves money |
FAQ:
- Question 1Should I ever close the washing machine door completely?
Yes, as long as the drum and seal are dry. After airing it for a couple of hours and wiping visible moisture, it’s fine to close the door fully.- Question 2How wide should I leave the door open after a wash?
A small gap of a few centimetres is enough. You want airflow, not a door hanging at its maximum angle all day.- Question 3Is mould only caused by closing the door?
No. Low-temperature washes, too much detergent, and skipped maintenance cycles also feed mould and residue around the seal.- Question 4Can a damaged rubber seal be repaired, or does it need replacing?
Light staining can be cleaned, but cracks, tears or warping usually mean a replacement seal is needed to avoid leaks.- Question 5Does this advice apply to top-loading machines too?
Partly. Top-loaders aren’t as hard on hinges, but it’s still better not to leave the lid permanently wide open and to clean the rim regularly.
