I'm not pleased with our new dishwasher.  The bottom rack does not come smoothly out.  Its back wheels get stuck in the space between the body and the door, causing it to crash down into this space.  Then, to get the bottom rack back into the body, we must lift up the back end of the rack to lift its back wheels up and out of the space where they're stuck.  We called our appliance company the day after the dishwasher was installed, but they could not send anyone out to look at the problem for two whole weeks yet.  So I don't know if this is an issue with installation, or with the unit's design.  Unfortunately, we're not pleased.
