Nice one. Just had same issue i.e. the washers on either side weren't great but weren't the issue. Issue is the internals get chewed up over time, maybe because the metal corrodes and then wears the plastic. Also, word to the wise if you do dissasseble the head, as you did with the screwdriver, the shaft of the little lever is very soft metal and liable to snap.......don't ask. Easiest option is a new head £12, rather than wasting time with the washer service kit....£4.......again, dont ask..Cheers.
Unfortunately topeak seems to have built several incompatible units all called "joeblow", even the specific model like this one "joeblow sport". Mine is probably closer to 10 years old and it doesn't have the same head design.

My Joe Blow Sprint floor pump does this and it’s brand new. 😢
Thanks for this!
