What should you check before buying?
If the machine will be near an occupied room, start with its stated spin-cycle noise level, then check it against the space available and the installation requirements. These criteria address different needs: a noise figure alone does not tell you how much vibration is transferred to the floor.
| Criterion | What to check | Who is it for? |
| Spin-cycle noise |
The noise level in dB and noise class on the European energy label for the exact model; compare machines with similar capacities too. |
When the machine runs near an occupied bedroom, I want to minimise audible disturbance during the spin cycle; around 36% of consumers would prioritise quiet operation. |
| Vibration and installation |
Whether the floor is level, and what the manual says about the feet, levelling and stacking the machine, if applicable. |
On a floor that is sensitive to vibration, I prioritise a stable installation over a single anti-vibration claim; stability would be the priority for around 29% of consumers. |
| Space and capacity |
The model’s dimensions, the depth required with the door open, the route to the installation space and the capacity in kg. |
In a smaller home, I need to be able to get the machine into place, open it and load it without sacrificing the capacity I need; around 21% of consumers would put this fit first. |
| Performance in use |
Whether there is a test of the exact model, including its noise measurement conditions and washing and spin-drying performance. |
If several product listings look similar, I prefer to compare them using measurements that also reflect how they perform in use; around 14% of consumers would consider this the most important check. |

Frequently asked questions
How do you compare the stated noise levels of two washing machines?
For each specific model, compare its airborne acoustic noise level during the spin cycle, in dB, and its class on the European energy label. These figures alone do not measure vibration transmitted through the floor, so also check the installation requirements and, if possible, a test of the model in question.
Does an anti-vibration feature mean you don’t need to adjust the feet?
No. A stated anti-vibration feature does not replace the installation instructions for the model you buy. The Bosch WAN24209FR manual says that all feet must rest firmly on the floor and that incorrect levelling can cause excessive noise and vibration.
Can you put a tumble dryer on top of any washing machine?
Don’t assume that any two appliances can be stacked. Check the manuals for both models and make sure the stacking kit is compatible before you buy. For the Bosch WAN24209FR, the manual requires a stacking kit from the tumble dryer’s manufacturer. This instruction applies to that installation and does not cover every brand.
What else should you check on the energy label besides noise?
For household washing machines covered by European energy labelling, the European Commission says the label also provides information about energy and water consumption, as well as the Eco 40-60 programme. Check the details for the model you’re considering, and separately confirm its dimensions and capacity are suitable for your space.
