Get the base model of whatever the consensus on brand is generally. ALWAYS research though. They all wash dishes, usually the biggest problems people have with dishwashers is user error stuff. Like not knowing you need hot water at the sink first before starting the dishwasher. which pulls from hot water pipe, but the water in the pipe is not even warm yet by the time it stops calling for water if you just start it. Same with not adding dishwasher detergent to the pre wash cycle, adding too much detergent to the main cycle spring loaded container, not accounting for hard water streaking and failing to buy a streak/rinse aid, not cleaning the filters or door seals regularly, buying a shitty detergent and not trying others, etc.
