The best dishwashers help you achieve the dream of getting back more time in your day. It's hard to overstate what a difference one makes, because you save that little bit of time every single day.

Getting a freestanding or built-in dishwasher for your kitchen means you can enjoy mealtimes without having to dwell on the clean-up operation that comes after, allowing you to relax with a digestif and let dinner go down in style, with the reassuring background hum of your dishwasher doing all the hard work for you. If your current machine is getting a bit past it, now is the perfect time to treat yourself to a new model. 

What is the best dishwasher?

The best dishwasher right now if you want cutting edge cleaning and perfect drying is the T3 Award winning Bosch SMS67MW00G PerfectDry. 

But if fancy dipping your toes in a little deeper, then opt for the excellent AEG FSS62800P. This one offers a lower crockery shelf that rolls out then actually rises up to around waist height for easy filling and emptying. A raft of other great features is also built in to this flagship machine. 

However, there are plenty of other quality options below, with the likes of Miele, Siemens and even budget-brand Beko wading into the arena.

How to buy the best dishwasher

If you've not bought a dishwasher for a few years (or ever) you may be surprised to find that the cutlery basket at the bottom is now a cutlery drawer at the top. We initially found these fiddly to fill – more so than dumping a load of spoons and forks in a basket, certainly – but we've come to appreciate the improved cleaning and increased space on the bottom shelf.

By definition however, cutlery drawers do leave less space in the top shelf, so tall wine glasses, for instance, will now have to be relegated to the bottom.

That aside, buying a dishwasher is pretty simple: measure up, pick a budget and get down the shops to inspect the goods, if possible. We don't recommend slimline dishwashers unless space is really at a premium; they're just never as good (and usually, not very space-saving either).

We don't really subscribe to the idea that there is a 'correct' way to load a dishwasher. So long as you don't totally overload your machine, and keep it topped up with salt and rinse aid, you should get decent cleaning results for years, even from the better cheapo machines.

But how do you know which ones are better? Easy. These are the 7 best dishwashers, with our favourite first and the rest in roughly descending order. 

Take up your tablets, rinse aid and massive bag of cheap salt and prepare to learn T3's choice of what the best dishwashers you can buy today are…

1. Bosch SMS67MW00G

Bosch! It's the best dishwasher you can buy

Type: Freestanding
Place settings: 14
Energy rating: A+++
Size: H 845 x W600 x D680mm
Reasons to buy
+Bosch build quality+Lots of capacity+Very quiet
Reasons to avoid
-Energy rating

Bosch produces lots of dishwashers and most of them are exceedingly efficient and highly reliable.

The T3 Award Winning SMS67MW00G is a top-notch example that features Bosch’s PerfectDry technology. In a nutshell, it uses zeolite, a magical mineral that turns moisture into heat, in this case to dry dishes without using extra electricity. And by dry we mean bone dry – plastics and all.

The SMS67MW00G has lots of other features to offer anyone with piles of dirty dishes to get clean. There are 14 place settings and the way the unit has been designed means you can easily find a home for any grubby plate, cup, or item of cutlery, along with pots, pans and all the rest of it. We love the Vario basket system and cutlery top-mounted cutlery tray, too,

Choose from any one of seven programs with a host of temperature settings, with a quick wash option clocking in at just 29 minutes for those with an urgent need for a dinner setting. We’re also impressed with the ExtraDry program that reduces streaking, while the Glass 40°C wash is ideal if you have a lot of delicate glassware to get through. This machine also scores highly for its low noise operation, thanks mainly to its clever Silence function.

If you’re scouring the market for superbly specced premium machine at less than premium prices then put this at number one on your shopping list. We have.

Beko DEN59420DX

2. Beko DEN59420DX

Best cheap dishwasher

Type: Freestanding
Place settings: 14
Energy rating: A++
Size: H 850 x W 598 x D 600mm
Reasons to buy
+Great price point +Excellent cleaning +Handy wireless smart functionality 

There have been a few 'smart' dishwashers with wireless connectivity before but Beko has now added it to the DEN59420DX free-standing dishwasher without charging a big premium for the privilege. The resultsant Smart Dishwasher is a very affordable option, but it still comes in sizzling stainless steel and is packed with features and functionality. 

As well as having a good energy rating, the DEN59420DX dishwasher also features AutoDosing technology, which means sensors work out just how dirty your dishes are and adjusts the detergent and rinse accordingly. Rather than adding powder, liquid or a tablet with every wash, you can fill a reservoir that only needs topping up 'once per month' (depending on how many dishes you wash, of course…)

There’s a complete selection of program options to choose from while the Quick & Clean selection gets the dishwashing done in just under an hour. Impressive. Adding to the appeal is a ProSmart Inverter Motor, which promises quiet and efficient running. When dealing with tough stains, AquaIntense technology delivers a high-powered pressure wash using an additional spray arm inside the machine.

Using Beko's HomeWhiz app the dishwasher can be managed remotely – you can even order more detergent via the app, as well as downloading new wash programs and keeping tabs on cycles. There’s support for Alexa voice control, too. All the smart stuff is nice to have rather than essential, but it's the icing on the cake with this excellent, great VFM dishwasher.

Highly rated US-branded dishwasher with SaharaDry tech

Type: Built in

Size: W 24 inches (61cm)
Reasons to buy
+Popular American model+Dries dishes very well+Very quiet

As strange as it may seem to us Brits, the American dishwasher market doesn’t do stand-alone dishwashers. Maybe their kitchens are much better than ours. This top-selling built-in model from one of America’s largest kitchen appliance brands boasts automatic cycle times depending on how much of a wash the dishes require, SaharaDry tech that ensures all cutlery and crockery comes out bone dry, and one of the largest cutlery baskets on the market.

It has space for 14 place settings and comes with eight programmes, including a Quick 34 minute cycle for quick turnarounds and a sanitise cycle that is said to ‘remove up to 99.9% of household bacteria’. At 52dB it’s pretty quiet, too.

If you live Stateside and are on the hunt for a US-branded built-in dishwasher that’s garnered a wealth of positive user reviews, then this one is a very competent contender.

Bosch Serie 4 SKS62E22EU

4. Bosch Serie 4 SKS62E22EU

Best tabletop dishwasher

Type: Tabletop
Place settings: 6
Energy rating: A+
Size: H500 x W550 x D450mm
Reasons to buy
+Perfect for smaller homes+Easy to use
Reasons to avoid
-Expensive-Basic functions

Bosch doesn’t do things by halves although in this instance, perhaps it does. The Serie 4 is a table-top dishwasher for those who don’t have the space but still despise washing dishes by hand. 

It comes with enough space to accommodate six average-sized dinner plates, a few side plates, a quartet of mugs, a carving knife or two and a clutch of cutlery. 

Like most mid-priced dishwashers, it also comes equipped with a sensor that measures the level of contents within and adjusts water consumption accordingly. And because it’s pretty quiet, it shouldn’t disturb the peace if you live in a studio or open-plan.

The Serie 4 features five washing cycles from 40 to 70 degrees C, and does a solid job with most things. It’s pricy for its size, but if you're allergic to doing the washing but strapped for space, the Serie 4 could be an absolute godsend.

Miele G7150 SCVi

5. Miele G7150 SCVi

Miele delivers another superb machine

Type: Freestanding
Place settings: 14
Energy rating: A+++
Size: H 850 x W598 x D570mm
Reasons to buy
+Fast and efficient+Great at drying+Quiet operation
Reasons to avoid
-Fully integrated only

If you’ve got a family, or somehow manage to accumulate dirty dishes at an alarming rate then the Miele G7150 SCVi Fully Integrated Dishwasher fits the bill. It features the usual quality build that you expect from Miele, but the fully-integrated design is also perfect if you want a machine that’ll keep a low-profile and just get on with it.

It comes with 14 place settings and the cleverly designed interior means that it can cope with all kinds of curious kitchen cookware. The 3D MultiFlex tray makes a lot of sense if you’ve got a mixed bag of things to clean. The height can be adjusted to let you fit in just about anything, from small and large crockery through to glassware. The same goes for the FlexLine baskets that also aid filling up the dishwasher.

As for performance then the Miele G7150 SCVi has it all going on, with a tally of eight practical wash options. We like the quick powerwash setting that takes less than an hour and still does a fine job. Similarly impressive is the A+++ energy rating, which means the Miele gets the job done without using excessive amounts of water. However, the IntenseZone option is one to call upon if you’ve got particularly cruddy dishes to tackle.

Being fully-integrated means that sound from the Miele will be deadened by your kitchen units somewhat but it’s still super quiet. In fact, Miele has even built in an Extra Quiet function and that shaves even more decibels off its operating noise. So it’s fast, efficient and promises years of good service. What’s not to like?

Bosch Serie 6 SMV68MD02G

6. Bosch Serie 6 SMV68MD02G

Basically the #1 entry without the 'PerfectDry' feature

Type: Built in
Place settings: 13
Energy rating: A++
Size: H815 x W598 x D550mm
Reasons to buy
+Excellent quick wash programmes+Generally very quiet+Mysterious but useful-sounding 'intensity zone'
Reasons to avoid
-Not much space on that top shelf

This is a classic Bosch dishwasher. There's nothing very sexy about it, apart from the way it projects the remaining time for each programme on floor. But, it sure does wash dishes. And very quietly too, with a quoted loudness rating of 44dB, which can be cut to just 40dB by using 'SuperSilence' mode. 

The slightly iffy thing about this Serie 6 model is that it has about 900 wash programmes. However the great thing about it is that they all seem to clean really well. A 35-minute quick wash and 1-hour hot wash (65ºC) give really good results so long as you're not cleaning up after a barbecue or Sunday roast.

In addition, the longer programmes can be cut short by using "VarioSpeed+" – where Bosch comes up with these names from I have no idea.

The Eco wash seems the best all-rounder to me – slow but effective and, of course, energy and water efficient – but when shit gets real, there's a 70º intense wash. 

There's also an 'intensity zone' button which can be deployed with most of the programmes, and blasts the lower shelf with more water (on the understanding that that's where your really mucky roasting tins and so on will be). As to whether this actually improves cleaning performance, I have no idea, as things seem to come out pretty pristine regardless. 

The down side to the Bosch's design is the same as most dishwashers with a cutlery drawer at the top. It's fantastic for cutlery, and the bottom shelf has loads of space, but it leaves the top drawer decidedly cramped. You will have to get used to doing wine glasses at the bottom, or hand washing them, I'm afraid.

That aside, a textbook dishwasher. Those who hunger for more tech might prefer the Serie 6 SMI68MS06G, which is very similar, but supports Bosch's Home Connect app via a Wi-Fi connection. This supports remote control (not very useful) and also fault/sundries diagnostic info (potentially handy).


7. Siemens IQ500 SN258106TG

Best Siemens dishwasher

Type: Freestanding
Place settings: 14
Energy rating: A+++
Size: H845 x W600 x D600mm
Reasons to buy
+Flexible rack system+Dosage assist+Glass care function
Reasons to avoid
-Not cheap

This handsome silver-clad model has recently been added to Siemens’ ample roster and it’s a corker. The iQ500 isn’t cheap but you do get a shedload of beguiling features and functions for your dish cleaning needs.

Let’s start with its zeolite drying process. Zeolite is a clever little mineral that converts absorbed moisture into heat energy. In this instance it helps dry the dishes and is especially effective at making glassware shimmer. And speaking of glasses, the machine comes with a specific glass wash programme and a new wine glass tray so you can rest assured your expensive flute collection (the glass, not the musical instrument, obviously) will be gently cleansed and remain intact.

Other tempting features include a space-saving top-mounted cutlery tray, an outstandingly flexible three-position top rack system and one of the most user-friendly touch control panels on the market. The ice blue interior ‘emotionLight’ is a nice touch when loading the machine, though it mystifyingly switches off when you open the door after the machine has completed its cycle and switched itself off. One disgruntled user describes it as ‘a fridge light in reverse’.

This A+++ model is also equipped with a whisper-quiet, brushless iQdrive, Siemens’ ‘dosageAssist’ feature (pre-loaded detergent tablets are dropped into a catch pan where they’re thoroughly dissolved before dousing the dirty contents) and the bafflingly useless Home Connect system, which lets you control the dishwasher from your phone while lounging on Copacabana Beach. As you do.
