KitchenAid, Whirlpool, Maytag.

Don't get Kitchenaid for what you are asking for.

The wheels on their baskets are attached with chewing gum and matchsticks -- or so it seems. I have had the flimsy plastic parts break and the entire basket came crashing down. The good news is, the replacement parts only cost $20. The bad news is that the "new and improved" design only lasted a few months before the same thing happened again.

Also, interior organization is inefficient. And even if I load it very lightly, it won't clean all my dishes. I always have several dishes that I need to wash by hand afterwards.

The good news is, it's cheaper than high-end brands such as Bosch, Miele, or Wolf. So, for an infrequently used dishwasher, it might still be worthwhile all the downsides.

maybe you have a dud. Our 800 series Bosch does most things quite well and parts seem durable

Agree that it might somehow be your specific dishwasher. I load my Bosch to the max with Fiestaware of all shapes and sizes every day without incident. That dishwasher is the workhorse of my kitchen. Love that thing. Not saying you can’t/shouldn’t replace it, it could somehow be a lemon, but not sure it’s an all Bosch issue.

I'm afraid I agree that I got a lemon, as almost no one seems to have this problem with their Bosch. The "wheels" don't actually turn; they are supposed to glide along the rack but don't. I wonder if there is a lubricant I could try on the rails that the wheels sit on.

Any lubricant that you could apply would almost certainly wash off the first time that you use the dishwasher. On the other hand, you could check whether there is any contamination that prevents the wheels from turning.

Remove the basket and see if the wheels spin (relatively) freely. Don't expect them to have any ball bearings and to keep turning like a fidget spinner. But you shouldn't need to exert any force to make them spin either.

If your Bosch is "relatively new," isn't it still under warranty? Have you called Bosch?

Good point on the warranty - racks are warrantied 2-5 years. Worth a call. Although the repair person said it was fine. I think it's a design flaw, but then again, why is only my dishwasher the problem.

The wheels actually spin ok. It's almost as though the rack and wheels aren't quite wide enough to maintain their grip on the side ledges of the dishwasher.

Unfortunately, even though I suspect this might be a "my" problem rather than a generalized Bosch problem, I don't know that I am willing to chance it.

If the wheels don't maintain grip, then that's probably intentional. It means that they are sliding so well, the wheels never even need to turn.

I have seen that across brands. So, I don't think that's unique to Bosch.

Your issue with the Bosch racks seems very unusual. Do you have a model number for the dishwasher?

Bosch has different rollers for their higher end racks but they will fit on the mid and lower end racks too.

I think there is a total of 8 rollers on the bottom rack do you have all 8?

Replacing the rollers would be a lot simpler than replacing the dishwasher.

SHX65T55 is the model number. I have all 8 rollers (the replacement ones) and the original 8. I don't think it's a roller issue. It appears to be a balance issue wherein if one side is even slightly heavier than the other, the wheels fall right off the ledge and that side of the rack comes crashing down.

Perhaps insultingly basic, but have you checked to make sure the DW level?
