How Much Does it Cost to Use a Dishwasher Once in My Kitchen? Is it Expensive to Operate Them?

Question

I was arguing with my mate about using our dishwasher in the kitchen. She says they are expensive to operate and use a lot, a lot of electricity. Is that true?
In our dishwasher ("AEG" brand) we have five programmes of use: Intensive (75); Normal (65); Normal (50); Eco (50) and Quick (50). Usually we use "Normal" or "Eco".
Can anybody estimate how much does it cost for any given household to run a dishwasher once? I think the water is not expensive - it's the elctricity that counts.
Do you think it costs £1.00 or more (or maybe even less!!!) per very use?
Thanks.

Answer 1

Your dishwasher will cost about 12-18p per full load depending on the programme chosen and your electricity cost. Plus the cost of the tablet.

Tonight I will measure the EXACT cost of a wash with my Bosch machine on a 35°C 'Quick wash', Cold fill, appx. 35 mins,@ 10p kw/h and post the result here.

IT COST - 9.67pence

They normally have a 2kw heater so it's like have an electric fire or a tumble dryer on, the amount of money does not really justify the result, u also have the cost of the dishwasher tabs, it may use 50p - £1 in electric but using a sink and some fairy liquid is better on your pocket and the environment. Dishwashers can also harbour germs and dirt, just check a 2 year old used machine. Yuk! and the water consumption is high too, i mean even most toilets will have a big and small flush issued now.

Answer 3

Do you mean the domestic cost or the environmental cost? I can never see the justification for a dishwasher in a small family. It never takes that long to wash up and group activities have important bonding functions. Having only used industrial dishwashers, I wonder if the time spent with adding water softener salt, cleaning the thing out, having to rinse the dishes anyway before putting them in and the time, water and elecricity used, makes any sense on a domestic level. They can remove the glazing on dishes and you still have to check how clean they've come out. Quicker, easier and cheaper to do them by hand, I think.

Answer 4

very expensive. Thursday is dishwasher night in the Khrewton household. We all gather round it, glasses of tang in our red, cracked hands....
a compromisial solutional possibility is to discontinue using it for say...half a month. Then check the bill and double the difference to see how much it runs you a month roughly.

Answer 5

Cheaper to wash dishes in dishwasher than by hand. You'll use more hot water by hand. Tell her to wake up.

Answer 6

The newer ones are more efficient both in electric- and water consumption. You will use less water than if you tried to wash and rinse in your kitchen sink. By using less water, you're also using less electricity to heat the same water.
