Our latest dishwasher group test has uncovered a new Best Buy slimline model that has beaten our Best Buy threshold by an impressive 10% to become the top-rated slim model on our site.
Slimline dishwashers don’t generally tend to pack as powerful a punch as full-sized versions, but the best can still leave dishes sparkling and thoroughly dry without guzzling more than their fair share of energy and water.
The new slimline Best Buy joins the ranks of five other slimline models that have earned our Best Buy recommendation – go to our area for full reviews and ratings of these top models.
Our latest test also included a mix of full-sized, built-in and freestanding models from brands AEG, Bosch, Electolux, Hotpoint, Indesit, Neff, Maytag, Smeg and White Knight.
Proving that the newest models aren’t necessarily the best, there we no Best Buy full-sized models in this latest group test. Though some scored well for the basic business of cleaning and drying, they missed out on a top score by being noisy or not as thrifty with energy or water as some machines we’ve tested. Some of these machines are budget-friendly, so if you’re on a tight budget and willing to compromise on a dishwasher with controls that take a little longer to get used to, or one that can be quite noisy, then one or two of the latest models we’ve tested could be a good option for you.
We currently have 22 other Best Buy-recommended full-sized models on Which.co.uk, including a budget option priced less than £250 and top-rated models that wowed us in the test lab to achieve a 83% total test score.
How we test dishwashers
No other organisation tests dishwashers a thoroughly as Which?, and because we’re independent and don’t accept advertising, we’re free to give each model an honest review that you can trust.
Dishwasher expert Yvette Fletcher explains the lengths we go to uncover the best and worst models: ‘We test every dishwasher on a load smothered in baked-on grime such as oats, spinach and egg yolk. The load includes plates, glasses, bulky items such as bowls and Tupperware and cutlery – this mixture mimics everyday use of a dishwasher, which isn’t always just filled with crockery and cutlery. It also helps us tell you how well a machine dries plastics and if it leaves unsightly watermarks.
‘We also measure how much water a dishwasher uses per load and how much it will cost you to run over a year. This way you can have an informed view of how good value it is, beyond the price you buy it for. Dishwashers often show improvements over time for efficiency on energy and water use.’
