Not happy with this purchase. For the price that we paid it does not clean very well. I’ve done everything they said use the cleaning agents they suggest and still dishes come out gritty even the tall glasses I put with the bottle jets come out Gritty. The bottom rack doesn’t make a lot of sense as far as positioning dishes and pots and pans. The third rock is a nice option but you have to take it out if you put anything tall in the upper rack even with the drop down and then you have to be careful what you put in the bottom cause then it hits in the tall stuff and the spinning jets. Have a tech coming out again. Maybe it’s just a faulty unit.
