I've only washed a few yeasts and reused them, they all took a little longer to start ~20-30 hrs. I think I just didn't have enough cells in each vial after washing. BUT they all worked eventually.
EDIT: FWIW, I always make a starter, even when using a dry yeast. I think if I try washing any yeast this summer I may try to step it up at least once to boost cell counts and see if that makes any difference.
I have vessels, some contain beer.
Reason: Additional thoughts
