Should you leave the washing machine door open or closed?

Generated by DALL·E

A habit that can get expensive: leaving the washing machine door open after a cycle feels natural. Air circulates, the tub dries faster, and mold is less likely. Yet many manuals insist on the opposite—close the door. This isn’t box-ticking; there are practical technical reasons behind it.

What manufacturers say

User guides differ. Some never mention door position, others call for closing it after every wash. Certain models are explicit: once the laundry is out, the seal and glass should be wiped, and the door closed.

Manufacturers stress that the door isn’t just a cover. It’s part of the safety lock system that keeps the cycle secure, especially at high temperatures and with substantial water inside.

The hidden risk of an open door

When the door is left open all the time, the hinges carry extra load. Over time they can sag—much like kitchen cabinet doors. The difference lies in the outcome. In a washing machine, that sag can stop the lock from engaging reliably.

As a result, the appliance may refuse to start. That’s a safety feature: if the door can’t lock tightly, the risk of leaks goes up, and water can damage your home and the neighbors below.

What about mold?

The concern is fair: a closed door means a damp drum, and dampness can cause odors. But leaving the door wide open isn’t the best answer either. There’s a middle ground, and the fixes are straightforward.

Leave it open briefly

After washing, wipe the seal and the glass, open the door for 30–60 minutes to let moisture escape, then close it.

Use a slightly ajar position

Some models have a limiter that keeps the door from sealing shut. If there isn’t one, you can gently support the door so it rests without putting weight on the hinges.

Close the door, open the dispenser

Pulling out the detergent drawer gives moisture another way out. It helps the interior dry without stressing the hinges.

A sensible compromise

Keeping the door wide open feels convenient, but hinge sag leads to repairs and sometimes part replacements. Sealing the door without any drying invites other issues. The better routine blends both: let the machine air out, then close it until the next load. It protects the hardware, saves money, and keeps the drum smelling clean—and it simply feels like the right balance between convenience and care.
