How long can washer laundry be left in machine?!

[Autumnalsky]

If I leave a load of washed laundry in the machine for about 3 hours before hanging it up, will it start getting musty?! Thank you!

Sorry for the typo - the subject was meant to say “washed laundry”.

It should be ok. You can always stick a rinse and a spin on before you take it out if it's a bit whiffy.

I'd be more worried that it was going to be really crumpled.

3 hours is fine. I would think it's very common to stick a load on before going to work in the morning and getting it out when coming home? Or popping a load on in the evening and dealing with in the morning. Wouldn't think too many people standing by the washer to empty it as it finishes.

Can you put it on rinsehold and spin when you are ready to hang it up? Stops it getting as crumpled.

Three hours is fine. I’ll left stuff for six hours if I’ve been late back home and it’s been fine.

As long as it's not overnight it's usually ok

It shouldn’t start to smell for quite some time 2+ days. Your drum needs to be cleaned.
Does your machine have a drum clean cycle?
If not google drum clean, twice a year I run soap, bleach and a dishwasher tablet on the longest hottest cycle (mines actually called drum clean, my neighbor says sanitize). There is also a filter that needs checking monthly (behind a small unmarked door) and the rubber seal that needs wiping of soap scum.
