Every single dishwasher that we test has been purchased by us in the same way that you would buy a new dishwasher. We don't accept free samples from manufacturers, so we are completely unbiased in our verdicts.
During testing, all dishwashers go through the same assessment process to check how their wash cycles tackle a range of food waste, including dried-on spinach, porridge and egg.
As loading a dishwasher can be a constant source of arguments, our tests reveal the models that will help ease household hassle, and the ones that will further inflame domestic dust-ups.
Browse our dishwasher reviews and you will see models that have gone through the same robust, rigorous and real-world programme of in-depth testing.
We go further than anyone else to unearth the top performers that are worth your money, and expose the poor quality models that aren't up to the job of cleaning your dishes.

These are the most common, mainly because you can put one anywhere with access to a drain and a plug socket. The door is designed to remain fully visible.
Designed to be incorporated into a built-in kitchen, these are entirely hidden behind a cabinet door.
Although quite rare, semi-integrated dishwashers combine the functionality of a freestanding model with the streamlined look of an integrated dishwasher.
Dishwashers come in three different sizes: full-sized, slimline and compact. If you're fitting a new dishwasher into an existing kitchen, you'll need to measure the width of the space you plan to put it in.
You're better off going for a full-sized dishwasher if you have the space. Slimline dishwashers can sometimes be trickier to load, and our lab tests reveal that they use about the same amount of energy and water as a full-sized model – meaning that, per item, they’re actually less economical.
Width: Approximately 60cm.
Pros: They can wash at least 120 items at once, and are generally more efficient with water and energy.
Cons: They might be too big for small kitchens. Households that don't use much crockery could struggle to make up a full load, and running the dishwasher when it isn't full wastes water and electricity.
Capacity: 120-150 items.
The smallest full-sized machines have room for 12 place settings – each place setting is made up of 10 items, so that's 120 plates and pieces of cutlery as well as pots and pans in total.
The biggest dishwashers can squeeze in more than 150 items, so they’re capable of coping with the washing-up after a large dinner party or family get-together.
Width: Approximately 45cm.
Pros: A great option if you're short on space.
Cons: Not as energy- or water-efficient, per item, as a full-sized machine.
Capacity: 90-100 items.
Slimline dishwashers are 15cm narrower than full-sized models, but are still capable of washing nine or 10 place settings.
Discover the best slimline dishwashers according to our tests
Width: Approximately 55cm.
Pros: A good choice if you don’t use many dishes or are tight on space. With a table-top model, you don't have to bend down to load the dishwasher.
Cons: Often quite expensive and usually a lot less energy-efficient than full-sized or slimline models. It can be tricky to fit large items inside.
Capacity: 40-60 items.
Compact models can be either integrated or table-top.
They're slightly bigger than a large microwave oven or a big drawer. They can only hold between four and six place settings, and use more water and energy per item than slimline and full-sized machines.

Based on the latest energy price cap level, valid from October 2024, the most expensive full-sized dishwasher to run will add £96.30 a year to your bills, while the cheapest full-size model will add only £47.45 a year.
Use our running cost tool below to find the dishwasher that will cost the most and the least over its lifetime. Use the search bar to find a specific model or brand.
Dishwashers have an official rating for energy efficiency, but this doesn't guarantee you're getting the most efficient machine. That’s where our expert tests can help.
When we test dishwashers, we base it on real-life scenarios, using the programs you use most often. We calculate the energy running costs a machine uses and find significant differences between the best and worst, regardless of the energy label.
In terms of water use, full-sized machines use just half a litre per place setting. Slimline models tend to be less economical, but the most efficient we've tested still used less than a litre per place setting – far less than the amount you'd use when washing by hand.

Our Eco Buy dishwashers perform well in our cleaning tests, while also being efficient and long-lasting. Buying an Eco Buy could save you as much as £45 a year in energy costs, which equates to several hundred pounds over the dishwasher's lifetime.

Smart dishwashers connect to your home wi-fi network and pair with an app on your smartphone or tablet. They used to be more expensive – usually more than £600 – but recently we've seen smart models available for less than £300.
Most allow you to start your dishwasher remotely, but some also let you automatically order more detergent on a timer and download new programs. This should give you greater flexibility, but we're not convinced it's worth paying more for.
Security update policies determine the minimum time in which a smart dishwasher brand will protect the appliance and app against emerging cyberthreats.
We estimate the lifetime of a dishwasher – the average time we’d expect one to last before it breaks down or deteriorates significantly – is 13 years. This is based on robust analysis of recent product surveys; it's a conservative estimate, so we’re confident that the genuine average is more than this.
We reached out to the biggest brands to find out more about support policies, and many are falling well short of this.

Even the most well-known and reputable dishwasher manufacturers can end up producing bad models, which is why it’s important to read our individual dishwasher reviews.
If you want an overall impression of how the different manufacturers compare, our annual survey of thousands of dishwasher owners reveals which brands have the happiest customers and produces the most reliable machines.
We use the data to rank dishwasher brands by their reliability rating – you may be surprised to see where popular brands such as Zanussi and Whirlpool are placed.

If your dishwasher develops a problem, you can try a number of things to try and fix it. Read our guide to common dishwasher faults and how to fix them.
However, some more critical issues might require the help of a professional, such as major problems with the water pump or electrics.
Repairing will not only save you money but also reduce the environmental cost of recycling and producing a new one.

Some problems might be so expensive to fix that it's simply not worth the cost to keep your dishwasher going. In this instance, you might need to upgrade to a new model.
Many appliance retailers offer to remove your old dishwasher when installing the new one, although sometimes you do have to pay for this.
Another option (which might not cost anything) is council pick-up. Many councils let you dispose of one large item per year for free, charging for any more in that year. For more information, search your local council website for large item collection.
You could take your machine to a local recycling centre. Every item that has a plug, a charger or batteries, or it carries a crossed-out wheelie bin logo, can be recycled. If it's still in working condition, you might want to sell it second-hand (more on that below).
