I think it would depend on how flimsy the plastic is. We don’t have plastic cups or bowls. Our plastic storage containers are pretty thick, so they hold up okay. But the lids that are “softer” do warp a decent amount.
I also try to run cycles when I’m home. When the cycle is finished, I open the door a little bit to let the steam out, then I try to sweep off standing water (like on the bottom of bowls), and then I close for ~30 mins. That normally dries things quite nicely. And then I leave the door ajar to allow stuff to cool.
I really like our 3 year old Samsung. I don’t use it for pots and pans, or plastic, but it does a fine job on dishes, silverware and stemmed glassware.
Heated drying seems like a waste of money to me. I use a no-heat mode, pull out the racks when the load is done and still hot, wipe pooled water off the bottom of mugs with a towel, and dry wine glasses by hand. Everything is dry in an hour or so.
I love using good stuff, but equally love dinner parties where we use presentable stuff that all goes in the dishwasher! Husband says why have it if you don’t use if. I answer that using it for 4 is a lot different from using it for 8!
Well, for instance, my late MIL left her vintage Waterford crystal (not our style so eventually donated). I’m sure it was technically ‘safe’ but due to possible moving around and cracking I washed it. I have other similar things.
I break one or two a year. Tritan glasses usually bounce on wood, but they almost always break on tile, which unfortunately is what we have in the kitchen.
When I used conventional glass they broke all the time, a dozen probably didn’t last two years.
