What is the decibel level of a quiet washing machine?
A quiet washing machine produces a spin noise level of 72 dB or less and a washing noise level of 52 dB or less. Only 36% of washing machines fall into this category. Super-quiet washing machines have a spin noise level of 70 dB or less and a washing noise level of 50 dB or less, with only 15% of washing machines qualifying as super-quiet. You can find the noise level on the energy label of each washing machine.
Spin noise level is the noise during the spin phase, which is the loudest part of the wash cycle. It ranges from 64 dB to 85 dB, with an average of 75 dB. The scale is logarithmic, so small increases in dB represent significant increases in noise. Noise levels can be categorized as follows:
- 70 dB or lower is super quiet (10% of washing machines): equivalent to the noise in a busy restaurant or noisy office with ringing phones.
- 71-72 dB is considered quiet (26% of washing machines): comparable to a running shower or a car traveling at highway speeds.
- 73-76 dB is average (35% of washing machines): similar to a loud radio or TV in the home or a flushing toilet.
- 77 dB or more is loud (29% of washing machines): similar to an alarm clock or a garbage truck compacting trash.
Wash noise level is the noise during the wash phase (measured during the ECO 40-60 program), which is usually quieter than the spin phase. It ranges from 45 dB to 62 dB, with an average of about 53 dB. The categories for washing noise are as follows:
- 50 dB or lower is super quiet (15% of washing machines): equivalent to a quiet library or whispered conversation.
- 51-52 dB is considered quiet (21% of washing machines): comparable to a quiet office or light rain
- 53-56 dB is average (37% of washing machines): similar to normal household conversation
- 57 dB or more is loud (28% of washing machines): comparable to normal office noise where people talk or larger air conditioners.

How energy-efficient are quiet washing machines?
Quiet washing machines are generally energy-efficient. Most quiet washing machines belong to energy class A (53%), followed by class B (22%), class C (15%), and class D (10%). For comparison, 39% of all washing machines in the overall market belong to class A. Quiet washing machines consume between 40 and 70 kWh per 100 cycles, with an average of 51 kWh (is 4 kWh less than the market average of 55 kWh).
Energy consumption generally aligns with energy classes: A class typically uses under 49 kWh per 100 cycles, and B class under 55 kWh. However, this correlation can vary slightly depending on the machine's capacity.
There is a modest correlation (0.29) between spin noise levels and energy consumption, meaning quieter washing machines tend to use less energy. This is often because these washing machines feature advanced technologies, such as inverter motors, which also improve energy efficiency.
In terms of water usage, quiet washing machines use between 40 to 70 liters per cycle, with an average of 48 liters (2 liters more than the market average of 46 liters).
What is the spin-drying efficiency class of quiet washing machines?
Quiet washing machines usually have a spin-drying efficiency class between A and C, with class B being the most common (93% of quiet washing machines). Spin-drying efficiency class refers to how well a washing machine removes moisture from clothes during the spin cycle.
Spin-drying efficiency class is closely related to the maximum spin speed of the washing machine. Maximum spin speed varies from 1000 to 1600 RPM in quiet washing machines, with 1400 RPM being the most common (80% of washing machines), followed by 1200 RPM (15%).
Higher spin speeds generally result in lower moisture retention: at 1600 RPM, clothes retain about 43% humidity; at 1400 RPM, about 50%; and at 1200 RPM, about 53%. However, washing machines tend to get noisier as the spin speed increases because the drum rotates faster, creating more friction and vibration. Modern washing machines often include features like improved insulation, shock absorbers, and balance systems to reduce noise even at higher spin speeds.
If you often wash delicate clothes, you should also consider the minimum spin speed. Delicate fabrics require lower speeds to prevent damage. The minimum spin speed in 8 kg quiet washing machines ranges from 400 to 800 RPM (with 80% of them capable of reaching the lowest possible spin speed of 400 RPM).
