Question about Siemens Wd15h541ch

I have had very good experiences with this machine, but I am alone. A wash cycle with drying takes max. 5h23' depending on the programme for 4 kg (no longer possible with drying). If you can put this time overnight, no problem. If there is an additional drying option, 7 kg is also possible. I always wash 7 kg, and then dry in 2 stages. The laundry is also nicer and goes faster.
