A:Answer Hi Lynn.
Thank you for reaching out regarding your Samsung - StormWash 24" Top Control Built-In Dishwasher with AutoRelease Dry, 3rd Rack, 42 dBA if the 3rd Rack can be removed. Regarding your concern, the 3rd Rack can be removed. These would be the steps:
1. Stand facing the dishwasher, and then pull the 3rd Rack out so that the handles at the ends of the rack supports are even with the end of the Rack.
2. With your right thumb, find the small indentation on the inside of the left rack support that houses the tab for the handle lock.
3. Push the handle lock tab in (i.e. to your left) with the tip of your thumb, and then pull the handle towards you until it disengages from the support.
4. Repeat this process with the right handle using your left thumb.
5. When the handles are removed, remove the 3rd Rack from the dishwasher.
6. Reverse the order of removal to re-insert the 3rd Rack.
