Weird thing happened. I woke up this morning to water all over my kitchen floor. It appears the dishwasher filled on its own and didn't shut off, causing it to over-fill and leak. After bailing much of it out, I closed the door and it kicked on and emptied the remaining water. I turned off the water to it for now.

Not sure if this has anything to do with it, but I recently experienced another problem I thought I'd fixed. When running it on Quick cycle (50 minutes), it would change to 99+ minutes at minute 46 of the Quick cycle. I found a solution online which included running cleaner in the machine, then running it on Normal cycle with Air Dry. This was supposed to reset it somehow. It did, and I've run it without issue about 7-10 times...until this morning. It last ran yesterday just fine and I emptied the machine before going to bed.

I'm assuming there's an issue with a sensor that calls for water and/or issue with shutoff? Any advice appreciated.
