Maytag MDB4949SHZ. Dishwasher with built in food chopper. This dishwasher is 49 decibels. It has a stainless steel interior and stainless steel wash arms. Maytag is the only dishwasher that touts a non-filter dishwasher, and uses a chopper system to grind food debris and drain it out with the drain water. This dishwasher has the strongest motor, yet is quiet enough to have a conversation around while it’s running.
