They use less water (and so less energy) than equivalent sink washing.
I've often seen this stated. However, I presume once the energy consumption and environmental costs of manufacturing the dishwasher plus the end of life disposal/recycling costs are included, that dishwashers are nowhere near as environmentally better than handwashing as they are advertised, and possibly are much worse.
I make both my own dishwasher powder and dishwasher cleaner.
Interested, Cinnamongirl, what do you use?
they are not great at removing some areas of dirt and grime
What's the difference between dirt and grime?
Have you got one of those fridge things op or do you still use the cold shelf in the pantry?
Im sorry but I’ve used 3 or 4 different dishwashers now and they are all the same – Bosch ones at work, other quality brands elsewhere. None of them got rid of baked on stuff or porridge bits, they ruin glasses and are generally crap even when they are loaded lightly. Lightly used plates and mugs are fine.
I make no special efforts beyond scraping food off plates, yet I don't seem to have any of the problems you experience.
Dishwashers work by using surfactants, bleach and corrosive alkalis to clean, the spraying water action is minimal. Hand washing uses mechanical action and surfactants, so is more environmentally friendly, gives desk-jockeys much-needed exercise and teaches humility and the virtues of hard work. Your choice.

It's well accepted that water & energy use is lower in the dishwasher than hand washing, that is also assuming you wash it all in one go rather than several small washes through the day.

My wife couldn't load a dishwasher to save her life, she is banned from even trying now. As the only person who ever does any washing up in our house, whilst I don't mind it all that much, after many years of doing it all by hand I prefer having a machine to not having one.
Wash as you go FTW!
Bingo.
Takes two mins.
The uses less water argument seems to be bollocks as well. A quick google suggests I could be using 27 gallons of water. That's three firkins!!!
I could do the entire street's washing up before my taps could produce anywhere near that much water.
I can only assume that argument was dreamed up by dishwasher manufacturers, like coffee producers suggesting there is more caffeine in tea.
Also, dishwashers are massive. Do people run them half empty all the time? Or do they leave dishes festering for days? Eughh! Minging!
Live on my own, but absolutely hate washing up, so I wouldn't be without a dishwasher. Most used appliance in my kitchen after the kettle! Sometimes just dump plates etc in there over a 3 day period and wash when it's full.
Standing in front of a sink, carefully stacking stuff in an unsuitable rack, rinsing, drying.. that's for 1940s housewives, I thought.
Bingo.
Takes two mins.
Real or imagined? 2 mins per what? Per plate, per was, per random number of dishes between 1 and some?
How much water do you use to do 3 or 4 washes per day? How do you measure it?

Cool, so they're not for you, best of luck*

Have you got the ability to read what I’ve posted?

I originally asked why people use them as in my experience they are no better, and in a couple of ways worse than hand washing. I’d like to educate some people on the value of reading things though. 😉
@Gunz - I understand that commercial dishwasher tablets contain sodium silicate which rinses away food and soap deposits and is completely soluble in water. One can't however buy this. Home-made dishwasher powder does not give a shiny finish to crockery but this doesn't bother me. I use borax, soda crystals, citric acid, salt and essential oil and if you'd like the recipe just ask.
To clean dishwasher fill 2 dishwasher safe bowls with about 250ml white vinegar. Place one in the middle of top rack and one in the middle of bottom rack. Obviously nothing else should be in dishwasher. Run on the hottest wash.
I buy everything in bulk cos I make loads of other stuff too, latest is loo cleaner and hard floor wash.
I wouldn't be without one.
Ours is a relative cheap but well regarded Zanussi washer, and when combined with the cleaning power of the cheapest Aldi tablets does a brilliant job. Pretty much never have to wash anything afterwards, unless my wife loads it and jams the spinny thing with a big spoon.
Even my wife, who used to be very anti dishwasher, is totally converted. We moved from a house that had one to one without. It took 4 weeks until she demanded we get one.
I know how to use one, I know how to stack one.
Obviously not, or your dishes would come out clean like mine do. You do realise that there's a pre-soak button to press if you've got dried on food, don't you?
We hardly ever rinse anything, and still our stuff comes out pretty clean unless someone's stacked it wrong or a utensil has slipped below the cage and stopped a sprayer from turning. Ours broke a few weeks ago and I had to wait about ten days for a part, so we hand washed. I can confirm it was much more work.
Glasses etc come out pretty clean too. I CAN get the glasses sparkling clean, but it takes fresh hot water, lots of careful wiping and a second rinse, which means more time and water.
The uses less water argument seems to be bollocks as well. A quick google suggests I could be using 27 gallons of water.
Lol, you didn't think to try a bit harder with that improbable figure? I love how people on this thread are totally sure that everyone in the modern world is a total idiot and has been utterly duped, and only they are the special clever ones.
Our dishwasher uses 14l of water and about 1 kWh. The best new ones are about 9l of water. Try washing a whole day of dishes for 4 in 9l of water, see how you get on.
Anybody use one of those new fangled automatic washing machines?
I don't see the point and I think the rot set in when they brought out those top loading twin tubs.
What's wrong with an outdoor copper and a mangle? It gives you a bit of exercise and teaches you the humility of hard work.

This is a bit of an urban myth, your average dishwasher uses 6 gallons of water per cycle. If you compared 8 place settings washed in a dishwasher with 8 place setting rinsed and then washed under a running tap then yes, the dishwsher uses less water BUT who washes up under a running tap???????????

Don't think this is true. 14l according to my manual.

All this washing is a modern fad! Really you need to build up a proper good stink to keep the demons of disease and pestilence away, everyone knows that.
I am sure you guys will come up with loads of other figures to argue against this but the point of what I’m about to say is that “don’t believe what you read”. I know this might sound a bit Jivehunny but let’s look at those figures which suggests dishwashers use less water shall we? Hopefully it might sound a bit more Dave Gorman than conspiracy theory…..
Web page sponsored by Finish dishwasher tablets:
“Lab studies* found that washing up a full dishwasher-load by hand (12 place settings) took on average 60 minutes and 49 litres of heated water. An average dishwasher uses as little as 12 litres to do the same job, taking only 9 minutes to load and unload.”
*The “Lab Studies” is a report called “Manual dishwashing habits: an empirical analysis of
UK consumers”
The washing up they used in the study was “12 standard place settings of tableware, each composed of a dinner plate, a soup bowl, a bread and butter plate, a saucer, a cup, a glass, a fork, a knife, a soup spoon, a dessert spoon, a tea spoon and additional serving pieces.” So these are all the items which a dishwasher is good at cleaning. No frying pans/cooking dishes/baking trays etc. They could easily put those items in the most eco wash and they’d come out clean. Who uses 12 place settings with bread plates and saucers but nothing to cook the food in? And who takes 60 minutes to wash a load of dishes? Those dishes they have used in the test could all be washed in one bowl of hot water which is nowhere near 49 litres. An Addis butler bowl (bigger than a normal sink washing up bowl) holds 23 litres to the brim.
At the end of the report it says “The authors would like to thank Reckitt Benckiser Ltd and BSH Home Appliances Ltd for supporting this research.”. Oh really?? Reckitt Bensicker Ltd are a consumer goods company, the only product they sell which might be used in the washing dishes process is Finish. So they reference a report they paid for which then suggests using machines which need their products are better? What a coincidence…
Who are BSH Home appliances Ltd? It’s the “is the largest manufacturer of home appliances in Europe “ with brands such as Bosch, Siemens, Gaggenau and Neff. Well I never…
Interestingly on the same page there is a “savings calculator”. Even if you put the lowest numbers in (1 person cooking 1 meal a week which needs washing up) there is still savings to be made (3.7 hours, 156 litres and 1.73 kwH of electricity apparently!). So there is no way handwashing could save anything according to them. Wow!
8 place setting rinsed and then washed under a running tap then yes, the dishwsher uses less water BUT who washes up under a running tap???????????
I might wash using a single bowl of water but I always rinse under a running tap rather than a single bowl otherwise I am rinsing in dirty water ?
Regarding hand-washing - why do some people not rinse stuff before putting it on the draining board? If I wanted my cornflakes to have a hint of fairy liquid I'd add it to the milk thanks!
Also I seem to be in the minority that insists on running water when doing the dishes, not a sink full of water that gets dirtier and dirtier - am I reckless with my environmental responsibilities?...
theres nothing quite like a glass of nice fresh water from the well with eau de fairy .....
I'm not apologising for my laziness newrobdob!
let’s look at those figures which suggests dishwashers use less water shall we?
No. I wouldn't care if my dishwasher used a whole bathtub full every time.
The uses less water argument seems to be bollocks as well.
My dishwasher uses 10 litres on the eco cycle and I can get three loads of washing up in it (breakfast, lunch and dinner). That's for a family of four.
If you're able to wash the same amount up by hand and use less water, then that's because you are disgusting.
I'm sure all those professing anecdotes over measurements know the capacity of their sink and tap flow rates
File dishwashers under 29ers and auto/dsg cars, everyone dislikes them until they've used one.
I like a bit of modern stuff. Living off the grid not for me.
I've solved the problem of needing a dishwasher by having three children.
Most of the dishes in the house do not require washing as they're currently hiding under beds or concealed beneath piles of clothes.
User error, or more likely, too mean to buy one.
I put stuff in, it comes out clean and dry.
Reading the OP, I’m assuming the fault lies with them or a poorly working dishwasher.
Probs the OP!
Woah there!
There's obviously a lot of people who give far more of a shit about washing up than I do.
Hand washing uses mechanical action and surfactants, so is more environmentally friendly, gives desk-jockeys much-needed exercise and teaches humility and the virtues of hard work.
I prefer wringing my hands together on here and storing up enough frustration which gets converted into words than "do the washing up"
The Dishwasher does the hard stuff, so I can vent frustration on here..
Like many I reckon..
Next someone will be telling me that our clothes line uses more energy than a tumble dryer 😉
Pointless in our house. We got shot of it when we had a new kitchen fitted. There's only 2 of us & I can wash up, dry & put away everything after making/eating Sunday dinner, in less than 10 mins. We did however, leave the pipework in so that when we sell the house It'll be easy enough to re-install one.
I'd rather have the cupboard space.
“

Ahh, so it’s really SLOB not SBOB 🙂

+1 & there's 5 adults in the house and a great cook too, wash up twice a day whilst spying on the neighbours

You live in a weird world where you are considered off the grid if you don’t have a dishwasher.
Bodgy - sorry that’s proper minging. 🤮
I want 2 dishwashers in the kitchen so there's always an empty one to load dishes into when the other is working.
Clean benches, no stacks of dirty dishes.... 🙂
