I will shop at Yamibuy sometimes and they have so many weird Kit Kats, red bean being one of the wierdest.

Any hardware store, Walmart or the such will have the stuff. Here is an example at Amazon.

You could add a Vapor Barrier Underlayment before putting the foam tiles down, they make carpet tiles that may work for you as well.

You will be fine with a high loop.

For sure find a way to add the high loop to your drain hose.

I had an issue recently with my dishwasher not draining at all. I ended up taking the hoses off the pump (underneath dishwasher) and found some grapefruit seeds that had got past the filtering stuff inside the dishwasher somehow and that combined with soap scum and/or grease finally clogged enough that no water would pass when the pump came on. It may be worth removing the hoses from the pump to look in them and the pump itself for clogging.

Good luck.

Sorry, can't do imgur here at work.

Yes, some need to be vented or have a high loop as shown in this picture. https://ggrhomeinspections.com/wp-content/uploads/2021/04/high_loop-300x266.jpg
