Taking into account cycle time which is well over an hour on water, which seems to pull from our hot water tank (as I found out a couple of times jumping into the shower after with no hot water) etc.?

£1-2 estimate?

How old is the dishwasher as I thought they all heated the water internally?

Have you tried googling your model to find the water consumption info etc?

Finance? Lol.

I think if you're worried about the cost, you should just wash up.

I believe that it's quite unusual for a dishwasher to have a hot feed; the ones that I have used in the past have been cold feed only. Is yours hot and cold feed or has it been connected incorrectly as a cold feed only machine to a hot supply? Certainly our current machine (Neff) is cold feed only and does all the initial rinsing with cold water.

most dishwashers ( unless extremely ancient) use less water than filling a sink (or two) with hot water and only heat what is needed .

Very old dishwasher? Mine is 10 years old, takes 40 minutes on a 40c wash and doesn't use much water, so about 20p.

I have a dishwasher but don't use it. Partly because by the time I've loaded it and unloaded it I could have done the washing up anyway, but also because it wants 90-120 mins to spray hot water over a few plates. And then there's the salt, the rinse-aid and probably something else to check and have to buy. Mug's game.

My washing machine can wash an armful of washing in a fraction of the time. Maybe I should put the crockery in that!

I had someone round from the water company the other day giving me tips on how to save water.

She said dishwashers are far more efficient (water saving wise) than hand washing. I spose it is to do with leaving water running. I said we never sue ours and ifnact I am going to get rid but she said from a water saving point of view they are very good.

NMight save water but not sure if it will cost me in electrcity!

On a 45C wash ours (bosch 4yrs old) uses <1kWh. No idea about water usage.

The 50C Eco wash takes twice as long and is not necessary most of the time.

So around 10p / day for power

Don't forget to add cost of dishwasher tablets (a lot more expensive than fairy liquid), machine salt, rinse aid and anti-limescale stuff.

Use the eco/short wash setting if it has one. We used the standard wash for years, which took 90 minutes. Our repair man told us use the eco setting, as a full wash was pointless for most things. It now runs in less than 30 minutes for a normal wash. Its only a Sunday lunch that need the full 90 minutes.

Same goes for clothes. We use the short wash on our washing machine rather than the main cycle. Unless you work in a garage or coal mine then its all you really need. My mother just bought a new machine and it has a 14 minute wash time!

If a machine shouldn't take longer than a person to do the same job.

had a quick look under sink, i think it is only cold feed, but has a plastic type bottle inbtween the pipe and connector?

so not sure why it would take the hot water from the hot water tank!?

will try the eco wash, thanks.

but yeah tablets aside, electricity etc.

Picked a dishwasher at random...

http://www.johnlewis.com/bosch-sms40t42uk-dishwash...

Specs

http://www.bosch-home.ie/our-products/dishwashers/...

On a 195 minute cycle, using my usage costs...

1.02 kWh = 11.06p (@ £11.06p per unit)
11.8L = 3.62p (@ 0.31p per Litre (142.35p per m³ for water, 164.70p per m³ for sewerage @ 90% utilization))

Total = 14.68p per wash. Or you could wash 34 dishwasher-loads with change from a fiver...

(I promise I have a spreadsheet to work all this out, honest...)

A lot of hate on here for dishwashers. Loaded correctly, a dishwasher gives far better results than hand washing, and helps to keep the worktops looking tidier so you load as you go.
