A noisy dishwasher can be a nuisance. It can disturb you while you’re trying to relax, and even keep you awake at night. That’s why quietness is one of the main things people look for when choosing a dishwasher.
Noise levels are measured in decibels (dB). The average budget dishwasher on the market in 2017 makes roughly 48-50 dB of noise, which is about the same volume as a normal conversation. Anything below 45 dB can be considered ‘quiet’.
While you might not expect there to be much difference between 50 dB and 40 dB, there actually is a big difference. This is because decibels are measured on a logarithmic scale, so a 50 dB dishwasher will actually sound about twice as loud as a 40 dB dishwasher.
Are quieter dishwashers more expensive?
In general, the more you spend on a dishwasher, the quieter it will be. While the average dishwasher makes about 48-50 decibels of noise, the most expensive dishwashers typically produce less than 45 decibels of noise.
However, the quietest dishwasher we could find (the Smeg DF614APX) is by no means the most expensive on the market, though it does cost over £500. There are also some very quiet dishwashers available for under £400 such as the Indesit Extra Cycle DIFP28T9A.
