Most(maybe all) HE washers don’t have mechanical flaps that hold back the liquids, they sit in plastic cups that empty by an overflow or auto syphon system when water comes out of a tube located above that tub or cup. It’s a fancy plastic cup. Every plastic common to appliance manufacturing is resistant to 5% acetic acid.

I just looked at the fabric softener cup in my washer, it’s HDPE(high density polyethylene). If you look at that chart you will see polyethylene is resistant to even concentrated acetic acid. The plastic bottle the vinigar comes in is made from a lower density polyethylene.
By the time the vinigar leaves the cup is already being diluted by the fill water causing it to overflow or start the auto syphon. It will not damage your washer, but even if it did, you can buy replacements for the entire soap tray for relatively little online. The same can be said for most other appliance parts with the notable exceptions being large motors and some brands control boards. There are tons of write ups, tutorials and videos on how to fix broken appliances and replace parts.
Yes, I was just being pedantic. Sorry to have triggered such an involved response, but thanks for all the information! From what I understand this is more of a problem in dishwashers, if you want to use it as rinse aid.

No worries, I am a fan of pedantry. The amount of involved in the response was just me getting mentally stuck in a washing machine hole.
