Best dishwashers 2020: Clean dishes and cutlery automatically

Trusted Reviews has definitively ranked all the outstanding dishwashers you can buy in 2020, including the best from Whirlpool, Indesit and Hotpoint.

Best dishwashers 2020: Which one should you buy?

The problem with buying a new dishwasher is they aren’t the sort of thing people buy regularly.

That means people don’t know what’s what, or what’s good value, or what the key features are to buy. The best models are designed to be super economical, so you can save water as well as time.

We’ve reviewed many dishwashers from all of the top brands, which you can read more about below, and there are five that we recommend from the list. You can read more about them below, but here we’ve listed the options for convenience.

  • Best overall dishwasher: Whirlpool WIO 3O33 DEL
  • Best budget dishwasher: Indesit DFP 27T96 Z UK
  • Best basic dishwasher: Indesit DFG26B1
  • Best slimline dishwasher: Hotpoint Ultima HSFO 3T223
  • Best budget slimline dishwasher: Indesit DSFO3T224ZUK

How do we pick the best dishwasher?

Every dishwasher is plumbed and run in first before we begin our testing. We fill each dishwasher with a typical domestic load of pots and plates, including wine glasses and plastics. We test the standard, main wash cycle and the Eco cycle on all machines, measuring the amount of water used, power used, time to completion and the noise during the fill and washing stages.

We also have three standard washing tests:

  • Dirty wine glass
    This test consists of dried-on wine in the bottom of a wine glass. We look for perfect cleaning, a good shine and no streaks. We also look out for common drying problems, such as small pools of water in the base of the glass.
  • Dried-on wheat cereal
    Always a favourite, this test consists of a bowl with dried-on wheat cereal that’s been left for 24 hours. It needs to be cleaned perfectly to achieve a good score.
  • Dried-on egg
    This is our toughest test. In fact it’s so tough that no machine has produced perfect results yet. We leave egg cooked in the microwave in a Pyrex bowl to dry for 24 hours, and we always place this item in the best possible place to get ideal results. Tough though it may be, the extent of the cleaning gives us a great insight into how well machines perform overall.

1. Whirlpool WIO 3O33 DEL

A super-frugal, powerful integrated dishwasher

WPintDW3O33 16

Ladies and gentlemen, meet the Whirlpool WIO3033 DEL, the first 10/10 dishwasher that’s ever graced the Trusted Reviews test bench. Whirpool has pulled off a corker in the integrated 14-place WIO3032, with astounding energy efficiency, outstanding racking space and unrivalled cleaning.

One of our favourite features is Whirlpool’s PowerClean, a turbo-boosting programme to really power-blast those particularly mucky dishes. It’s one of the quietest machines on the market too – even when it’s not tucked away behind a furniture door.

Very low running costs and amazingly flexible interior space finish the bill. If you’re looking for a built-in dishwasher for under £650, this is the only machine you need consider.

Dishwasher type: Full size, Size: 820 x 598 x 555mm, Rated efficiency: A+++, Number of place settings: 14, Number of racks: 3

2. Indesit DFP 27T96 Z UK

A basic-looking dishwasher, but a great performer with some neat features

A little basic in style and features, the Indesit DFP 27T96 Z UK won us over with its great cleaning performance and low running costs. Surely, they are the most important factors when thinking about a dishwasher?

Importantly, the Indesit DFP 27T96 Z UK gets the basics right. We found that it was very easy to load, and the Extra wash option lets you remove the top basket, so you can fit in large items. Those with a young family will like the Baby Care Cycle, which is designed to remove 99.999% of bacteria: great for baby bottles, teethers and toys.

Importantly, the Indesit DFP 27T96 Z UK is a great performer, dealing with our tough food tests with ease, making this dishwasher a great budget buy.

Dishwasher type: Full size, Size: 850 x 600 x 590mm, Rated efficiency: A++, Number of place settings: 14, Number of racks: 2

3. Indesit DFG26B1

Simple operation and a low price make this a great budget dishwasher

IndyDFG26B1 12

Not particularly fussed about chasing the latest bells and whistles, and simply want clean dishes at a low price? Then the Indesit DFG26B1 is the dishwasher for you. Its capabilities can be summed up in one small list, which is: one big central knob for selecting one of six programmes; buttons for on/off; a delay start; and the enigmatically entitled MyTime function, which shortens the wash duration.

Washing and drying performance are decent, if not exceptional, but you can’t argue with that sub £300 price. It’s reasonably cost effective too, racking up an estimated £60 a year in running costs. If you want better figures than that, you’re going to have to fork out for an elite king such as the Miele G 6820 SC.

Simply put, the Indesit DFG26B1 fulfils its duty as a basic, easy-to-use dishwasher with good eco credentials.

Dishwasher type: Full size, Size: 850 x 600 x 590mm, Rated efficiency: A+, Number of place settings: 13, Number of racks: 2

4. Hotpoint Ultima HSFO 3T223 W X

A slimline dishwasher that’s big on performance and flexibility




Although the Hotpoint Ultima HSFO 3T223 W X is a slimline model, it doesn’t ditch the features of its big brother, so you get the frugal A++ energy rating, nine programmes and wash options and 10 place settings.

Loading is really easy, with this dishwasher built to be flexible: the upper rack is height adjustable, there are fold-down tines for small saucers, and the bottom rack has fold-down supports for saucepans.

The key feature is the Zone Wash 3D jets, which spray water at key areas of the insides to really clean up your dishes. Results were excellent across the board, with only a bit of dried-on egg left in our harshest test. Our one minor complaint is that dishes could have come out a touch dryer at the end: however, there is an extra dry feature that uses a bit more power but does leave dishes drip-free.

You’ll get better performance from a full-sized dishwasher, but if you don’t have space for one, this is the next best thing.

Dishwasher type: Slimline, Size: 850 x 450 x 590mm, Rated efficiency: A++, Number of place settings: 10, Number of racks: 2

5. Indesit DSFO3T224ZUK

A powerful slimline dishwasher with single-button operation


If you’re after a simple and effective slimline dishwasher, the Indesit DSFO3T224ZUK gets most things right. With excellent wash results, even in our difficult egg test, this slimline model has cleaning results up there with full-sized models.

A few water marks remained on our dishes at the end of the cleaning cycle, so you might need a handy tea towel to clean up the last few drips for a perfect finish. An ‘extra dry’ option would have been nice to avoid this. We can’t complain about the running costs, either, as this model is super cheap to run.

Loading the dishwasher is easy, with the racks sliding in and out neatly. The top rack is height adjustable and can even be removed to let you clean extra tall items. Controls are just as simple with a Push & Go feature where you press and hold the button and a wash starts immediately: to be honest, it’s a bit of a gimmick.

Drying performance could be better, but the overall performance on offer here makes this slimline dishwasher a winner.

Dishwasher type: Slimline, Size: 850 x 450 x 590mm, Rated efficiency: A++, Number of place settings: 10, Number of racks: 2

How to choose the right dishwasher

What size do I need?

There are a few varieties of dishwashers. The most common are freestanding dishwashers that are 60cm wide, though there are also slimline dishwashers that are just 45cm wide that are good for small flats. Integrated dishwashers come in similar sizes, but are designed to blend in with your kitchen cabinetry. There also compact dishwashers that sit on the tabletop like a microwave, which are useful if you don’t have space for anything bigger.

Each type gives you a little flexibility depending on your needs, but here are a few more things worth knowing about before buying a new dishwasher.

How many place settings should I get?

Dishwasher capacity is measured by place setting – a single place setting consists of ten items of various sizes. A 60cm freestanding dishwasher typically takes 11 to 15 place settings. Slimline dishwashers typically hold 8 to 10 place settings and compact dishwashers around 8 to 10 place settings.

Do I need adjustable racks?

Another consideration is plate size. Not all dishwashers can take the largest plates, but some have adjustable racks to accommodate plates as big as 31.5cm in diameter. Check the maximum size a machine can take against your largest plates before buying.

Do I need fold-down prongs?

This is a great feature to have. Fold down prongs make it much easier to load large pots and pans when you don’t have any plates to clean. Cheaper machines tend not to have them, but if you can afford one that does, then you won’t regret it.

What’s a cutlery tray for?

Another useful feature is a dishwasher with a cutlery tray. This is dedicated tray at the top of the machine that means you have more space for pots and plates in the main part of the machine.
