Verdict
Combining some high-end features, including auto dosing, AddWash and SmartThings compatibility, with a more mid-range price, the Samsung WW90T684DLH is an excellent choice for those that want it all. Spin performance could be slightly better, but that’s a minor complaint about an otherwise excellent washing machine that removes stains well, even at low temperatures.

Introduction
The Samsung WW90T684DLH may have a mid-range price, but it flaunts many of the features that its higher-end siblings have.
These include a generous 9kg wash capacity, low running costs, auto dosing, SmartThings integration, AddWash and excellent stain removal even at low temperatures.
With a smart design and simple controls, this is an excellent washing machine.
Design and features
- Simple to use
- Auto-dosing detergent and fabric softener
- Connects to SmartThings
Samsung has perfected the art of making home appliances simple and uncluttered to look at. Rather than a front control panel that’s awash with buttons, there’s a simple LCD, a control dial and just a couple of buttons under the screen.
Power the Samsung WW90T684DLH on for the first time, and it runs through its initial setup, calibrating the drum and setting the default language. After that, the machine runs through a quick-start guide to show what all of the controls do. It’s a neat way of introducing the machine and means that the manual isn’t really needed.
All of the wash programmes are selectable by turning the dial on the side, scrolling through the options on the LCD. Neatly, each wash cycle is described in English (or your chosen language) and also includes the maximum wash weight. That’s really useful, as other washing machines that I’ve reviewed required me to read the manual to see maximum weights.
Once an option has been selected, the LCD shows the estimated wash time, although this will adjust once the cycle starts based on the amount of washing loaded into the machine.
There are override options, too. Exact choices depend on the wash, but there are options to change the spin speed and use the more advanced options, including Bubble Soak, which soaks items before washing them for improved stain removal.
This machine has Samsung’s auto dose technology, taking liquid detergent and fabric condition in the two large reservoirs in the pull-out drawer. It’s possible to override the settings and use powdered detergent instead, although if you’re primarily a powder user a manual-dose machine would make more sense.
The Samsung WW90T684DLH auto doses based on the weight of washing used. It’s possible to select an option to add more detergent for more stained items, but you can’t select the amount of liquid to dispense based on the manufacturer’s recommended dose. In practice, that didn’t affect my wash performance results.
This is a smart washing machine, so it connects to your network and is controllable via the SmartThings app. From the app, it’s possible to set the machine, although to start a cycle, the remote control option has to be manually turned on each time the washing machine is powered up. This is the same with all washing machines and is a safety feature, so that a washing machine can’t be started remotely when a child or pet could be inside the drum.
As well as duplicating the controls on the front of the machine, the app can also notify you when the washing machine has completed a cycle.
There’s a wide range of cycles available, including specials for wool, baby care, activewear and a hygiene steam option that uses steam to refresh clothes. The latter is great for anything with odours, such as musty smelling clothes that have been in a cupboard for a long time.
The more you use the Samsung WW90T684DLH, the more it learns how you use it, suggesting cycles automatically based on usage patterns. That certainly makes life easier and involves less scrolling through wash options.
There’s a large door, so loading the machine up – even with its maximum capacity – is easy. I would like a light in the drum, as you get with the AEG L9FEB969C.
As with most Samsung washing machines, this one has AddWash via the pop-out door on the front. At any point during a wash cycle, you can pop the door open and add any extra items. For those times when I’ve dropped something on the way to the washing machine, AddWash is a lifesaver.
Performance
- Decent running costs
- Excellent stain removal, particularly at low temperatures
- Very quiet
I tested the Samsung WW90T684DLH with my normal tests. I started with my 5kg load of washing on the Eco 40-60 cycle. By my measurements, this cycle costs a low 36p to run, making this one of the cheapest washing machines to run. On this wash, the B-rated spin cycle removed most water from my clothes, leaving 32.4% behind. That’s a good, result.
Performance is excellent, too. Putting my stain strip through the machine, I took before and after photos of the cloth. From left to right, the stains are red wine, oil, ketchup, orange juice and gravy. There’s a hint of red wine and gravy left, but the other stains have been removed; note that there are a few flecks of ketchup that can be scraped off or removed in a second wash.
Moving on to the 30°C Cotton wash, I was pleased to see that a cycle cost just 35p. Here, 39.6% of the water was retained, which is good (under 40%) but not the best that I’ve seen from a washing machine.
A lot of washing machines have a very efficient Eco wash, but can be more expensive to run on Cotton. Here, there’s not much in it. Stain removal was also excellent, with the stains largely gone.
One of the best ways to save money is to use a colder wash, so I ran the Samsung WW90T684DLH on its 20°C wash. Here, running costs dropped to just 29p for a cycle, although water retention jumped to 41.2%.
Stain removal was among the best that I’ve seen from any washing machine. Sure, there’s some visible red wine, ketchup and gravy left behind, but that’s to be expected at low temperatures. What this demonstrates is that for normally soiled clothes, 20°C is the only temperature you need.
To really take advantage of a washing machine, it makes sense to load it to the maximum each time it’s used. Running at a full load, the Samsung WW90T684DLH costs 49p per cycle. Assuming that 1370kg of washing is performed in the UK per year, this washing machine would need 274 full loads per year, resulting in a running cost of £75.16. That’s not the lowest costs that I’ve seen, but still very competitive.
