A dishwasher is an appliance that streamlines and simplifies kitchen cleanup. However, it is one of the loudest household appliances, notes CNET in its online dishwasher buying guide. Manufacturers now offer dishwasher models that are designed to run more quietly without sacrificing cleaning power.
CNET notes in its buying guide that the decibel setting of a dishwasher is the key to how quiet -- or loud -- it is. If you want to purchase a low-decibel dishwasher, you should seek out a model that has a decibel setting of 47 to 57 decibels. Low-decibel dishwashers will have heavy insulation to block out noise and reduce the decibel setting. CNET explains that individual manufacturers may have different brand names for a low-decibel feature.
Low-decibel dishwashers are designed to run quietly enough for you to do things like talk on the phone or watch TV while the dishwasher is running. This is possible because low-decibel dishwashers have more insulation than traditional models. For example, appliance manufacturer LG notes on its website that its low-decibel dishwashers have a damping sheet on the door that brings the decibel setting as low as 45 decibels.
Additional features that help make low-decibel dishwashers reduce sound are quiet motors, smaller water pumps and quiet water valves, notes appliance manufacturer GE on its website. However, owning a low-decibel dishwasher does not mean compromising on cleaning features. Low-decibel dishwashers offer deep-clean cycles, silverware jets for washing cutlery and digital operating panels. When purchasing a low-decibel dishwasher, you can choose from traditional models that use water or newer versions that clean dishes with steam.
Low-decibel settings are not a standard dishwasher feature. Thus, when purchasing a dishwasher, you will have to narrow down your options to those that offer a low-decibel setting. CNET suggests in its buying guide that you also consider features such as capacity, energy efficiency and filtration systems in addition to noise insulation.
