[ I am very happy with our Bosch. It is QUIET. You almost can not hear it running. I pre rinse but there is no need. Best dishwasher I have ever had. Did I mention how QUIET it is. Also, the water in it while washing approaches boiling point. Just be careful if you add a dish. It gets stuff squeaky clean. ]
I’ve heard that some models have a “LEGO Setting”....
I ask this because there are a lot of LEGOs in our household!
Oh and as a bonus, it dries differently than most dishwashers. Plastic can go anywhere.
As far as legos, throw them in a mesh bag and throw them in. Rinse them after washing still in the bag and then throw the bag in your dryer on its lowest setting for a few minutes. EZ Peasy. Dont touch the settings on the Bosh. Set it for heavy duty wash and just leave it there.
