Consumer Reports ranks Bosch models as the quietest dishwashers available in its 2013 rankings. In addition to Bosch, Consumer Reports also recommends KitchenAid and Kenmore models for low noise levels. Lowe's also recommends models from Bosch and KitchenAid as well as dishwashers from Whirlpool, Samsung, GE and LG.
As Lowe's explains, the best way to estimate a dishwasher's noise level is to check its specifications for the machine's decibel level. Lowe's considers quiet dishwashers to produce 50 decibels or fewer. The quietest machine available from Lowe's, as of 2014, measures 39 decibels. Bosch also makes machines that register 38 decibels.
