Best dishwashers 2021
Choose the best dishwasher for you
Buying a great dishwasher means kissing goodbye to washing up by hand. Our expert guide tells you what you need to know to buy the best dishwasher for your home.
One dishwasher may look like another, but our rigorous tests have revealed huge differences in how well they clean and dry. The best will leave your crockery gleaming, while the worst will see you standing at the sink re-washing still grubby plates and bowls.
Picking the right model for you also comes down to your budget, the size of your kitchen and the capacity and features you want.
Best dishwashers: what features should you look out for?
- Delay start - most dishwashers come with a delay timer, which allows you to set the dishwasher hours before you want the wash program to start.
- Adjustable racks - if you regularly host dinner parties you might want adjustable racks so you can fit platters and wine glasses in with ease.
- A child-safe lock - will protect your dishwasher’s control panel from curious little fingers.
- Smart features – this allows you to control and monitor your dishwasher remotely via an app on your smartphone or tablet.
- Automatic open door drying – this opens the door of your dishwasher slightly near the end of your wash to let the steam escape, allowing your dishes to dry better.
- Sensor wash or fuzzy logic – a more advanced feature, this measures how dirty the dishes are, and adjusts the temperature and length of the wash accordingly.
Best dishwashers for running costs
Be careful not to pick an inefficient machine. Although most models have an A rating for energy efficiency, this doesn’t mean they won’t guzzle gallons of water during each wash. Which? rates each machine out of five stars for water and energy use. Shop smart and you could save yourself £37 every year.
Our best buy not only ensure your items are left sparkling clean but also using less water in the process. If you only put your dishwasher on when it's full, the best will use less water than the usual washing up bowl, despite cleaning more than a hundred items.

Don't Buy dishwashers to avoid

How we test dishwashers
Which? is independent – we work for you, the consumer, so you can be sure that our dishwasher recommendations are influenced only by our test results. We don’t take advertising and we buy all the products that we assess ourselves. With more than 50 years expertise in testing appliances, you can trust that we’re the experts in separating the good from the bad.
Every dishwasher is assessed in the Which? test lab using a strict range of criteria. From how easy the machine is to load to how much water and energy it uses, our tests will reveal everything you need to know about a dishwasher.
Most importantly, we check how well each dishwasher cleans. We dirty dishes with milk, tea, minced meat, eggs, oat flakes, spinach and margarine, baking on these substances in a heated cabinet to ensure we give dishwashers a tough, realistic test. We then go one step further and add in some clean dishes to the load, to see if the dishwasher spreads grime around the dishwasher - you wouldn’t want to buy a machine that just moves dirt from one plate to another.
