At the current price cap rate of 26.11p per kWh, a typical dishwasher costs about 47.0p per cycle, which is £122.19 a year on the usage below.
This one cycles. It switches on and off rather than running flat out, so multiplying its plate rating by the hours it is switched on overstates the cost, often by a factor of two or three. The figures here assume it draws full power for the time shown, which makes them a ceiling rather than a bill.

Across the range of powers for this appliance class, one cycle costs between 31.3p and 62.7p. Your own figure is on the rating plate, usually on the back or inside the door, and it is the only one that is true for you.
Like a washing machine, most of the energy is heating water. Eco mode is slower and cheaper because it heats less and washes longer.
