Long story short, the dishwasher showed the E24 error once or twice a month at first. We thought it was just a weird glitch, but recently it would do it every time we would run the dishwasher. To fix it, we would just keep hitting the start button and typically on the third try it would work. However, I wanted to see why we were getting the error so I cleaned out the drain hose and checked to make sure the filter was clean. Unfortunately this lead to us getting the E24 error every time we would run the dishwasher. It would start fine, but then when it went to drain the second time (about a minute into the cycle) it would stop, beep, and show e24 on the screen. We had a technician come out on Monday that checked the float sensor and that seemed to fix it for a few washes before we got the error again. I’ve checked the drain hose again and it’s not clogged, same with the garbage disposal, and I’ve cleaned the filter and made sure the propeller can spin. Now it seems to be running again after I’ve done those steps, but I’m not sure how long it’ll run for.
My dad also noticed that on the left side of the dishwasher, this circular thing which I could unscrew was leaking water. I’m not sure if that has anything to do with the issue.
I just want to know if there’s a more definitive fix for what’s going on, as it’s really annoying. I’ve attached pictures of the circular thing that’s leaking, the error code we’d get, and the model number of the dishwasher.

Roughly every two weeks the drain in our bathtub will clog. When my dad goes to clean it, there’s barely any hair or sludge that he can remove. He says the drain smells like rotten eggs when he goes to clean it, and the only that seemed to help clear out the blockage somewhat was when he used a drain snake to clean the u-bend in the bathtub. However even when he used the drain snake, almost nothing seemed to come out. My dad would like to know if there is something better he can do to remove the blockage or if there’s something else that he should check. He knows way more about doing home maintenance than I do and the pictures I’ve attached are of the drain, along with my dad cleaning the u-bend with the drain snake.
