You definitely don’t need that much vinigar. That said most new washing machine are using a chemical resistant silicone or TPE instead of more traditional rubber compound. This eliminated the already miniscule risk of acid damaging the seals.
If you add 3 cups(about 700 mL) of standard 5% acetic acid bleach to 4 gallons of water(~ 15000 mL) you end up with a 0.2% acetic acid you will end up with a pH of something like 5.5 or about the pH of healthy skin. A lot of HE washers will use a 5 gallon initial wash so it’s likely to be even gentler than what I came up with in my rough napkin math guesstamate.
While I agree with the general sentiment, the vinegar won’t be released and diluted until later in the load, so it sits in its full 5% acetic acid glory for quite a while.
