Anyone know wtf is wrong with my dishwasher?

After some googling I found out that some water can pool up in the basin and for some reason the trip the sensor that makes it think it has to drain so the drain pump keeps going.

I pulled out the washer to look under it and when I tilted the machine, more water started coming out, and I’m assuming that was sitting in the basin it was talking about. And the placement and amount of water seemed to be exactly where it was before when we got back from vacation, so I believe it came from the machine this same way and not through the seal/gasket. After doing this and all the extra water coming out, the pump was no longer running.

I then ran a load while I was awake and it did it’s thing like normal with no water coming out. However I did notice that sometimes it seemed a little louder than before, and I could have sworn I noticed a smell that reminded me of the smell of my washing machine when one of the rubber belts was burning up.

I also noticed that my machine did not dry very well, however I’ve had issues with my dishes drying properly for a long time and haven’t found much in regards to what I should fix and they recommend some kind of drying agent which I have still never tried.

That said, the dishes washed though so I’m not really sure. I think the water pooling up in the basin means something else is definitely wrong but I’m not sure what to do and try to figure out now, because I am assuming that this will eventually happen again.
