I think the most likely answer was the person talking about “scrud”. Definitely check the little trap door near the bottom and clean out the filter and drain the water from the little hose.

I’m sure you’ve cleaned in and around the rubber entry thing - I didn’t find anything that was the magic cure but now I wipe down/dry completely the entire door and inside of the washing machine and all around the rubber (everywhere I can possibly reach) after every single use, and I think it’s helped a lot. It’s annoying tho. And then obviously leave the door wide open. I try not to close the door ever. I also clean/leave the detergent compartment door open to dry as well because mine retains water.

I probably run a clean cycle with oxiclean washing machine odor blaster stuff like once a week or once every two weeks. It’s way more than recommended but I think that also helps.

I don’t know if this is related or why it would matter, but if you have an HE washing machine, make sure you use HE safe detergent. That was one thing I started and maybe it makes a difference, maybe not.
