Ok, I hooked up the dishwasher that Dave B donated, and it appears to be working at least through a rinse, I didn’t have time to run a full cycle.
It still needs to actually be attached to the counter top to prevent it from tipping forward during loading, but I’d like to hold off on that until we are sure it doesn’t leak - it did at first because I had not screwed down the drain line clamp tight enough. I also wouldn’t mind somebody with more plumbing experience taking a look at the set up.
Also needs a thorough disinfecting, maybe a couple of wash cycles with some bleach added will be enough?
