Three new washing machines from different brands have been awarded Best Buy status following latest Which? washing machine tests.

We've tested new washing machines from leading brands including AEG, Beko, Miele, Hotpoint, John Lewis, Siemens and Zanussi, ranging in price from £200 to £600. 

Our rigorous laboratory tests found that three washing machines do such a brilliant job of blasting stains from clothes that we're more than happy to award them our highest rating – the Which? Best Buy.

At the other end of the scale, one washing machine was so poor at rinsing washing powder away, that it was inches away from being rated a Don't Buy.

Best and worst washing machines

There are massive differences between the best and worst washing machines tested by Which?. 

A washing machine with five stars for washing will do a very good job of removing stains – in our tests this means that 85% of the toughest stains including red wine, grass and tomato sauce will have vanished. 

But a washing machine with only one star will leave around 40% of the stains still on your clothes.

Washing machine testing secrets

As well as checking how well each washing machine can wash clothes, we also test how well each washing machine rinses away detergent. This can be important to you if your skin is sensitive to washing powder, but also, nobody wants their clothes dotted with white flecks.

We measure how good the rinse is by stopping the washing machines mid-cycle and removing the clothes from the drum just before the machine begins to spin. 

We then transfer the clothes to a standalone spin-dryer that spins at 2800rpm – that's twice the speed of a fast-spinning washing machine.

We collect water spun from the clothes and compare its alkalinity to the tap water we used in the wash. Washing detergent is alkaline. The more alkaline the collected water, the poorer the washing machine is at rinsing.
