I have one of those plugs which tells you how much energy something uses and my old Bosch on the medium setting was 1.65 kWh. In my cheap Octopus window that costs me about 8p at the moment (though that tariff will rise by 50% at end May).
I'll check the newer machine sometime but I doubt it'll be much different.
On a good day in the summer most (all?) of that power can be supplied by the solar panels.
Nevertheless I still wash some stuff by hand - as above, I usually don't put the pots and pans in the dishwasher. It is one of those chores which has never bothered me that much.
