Just looking at the manual for my old machine. The ‘express 20 minutes” cycle uses .3kwh, washes at 40 degrees with a maximum load of 3.5 kg.
The cotton wash uses .34kwh for a 40 degree wash with a maximum load of 8kg.
The quick power wash uses .75kw at 40 degrees, max load 5kg.
The shirt cycle uses .76kw at 60 degrees with a max load of 2kg.
Interestingly the 20 degree cotton cycles uses more than twice as much water, 72 litres, as the 40 degree cycle 34 litres
Well worth checking the manual.
