Washing machines.

I took delivery of a new washing machine on Thursday.
I had ordered it online as currently I am housebound. The prices astounded me as some were as much as £1500 , I assume they wash, iron ,fold and then put away .
I paid £370 for a pretty basic washer on the premise that at my age it will "see me out".
I cannot believe though however simple I thought it would be, just how many programmes there are and different options even in each programme.
So, my question or point is, how many programmes do you all use?
As with my last washer I anticipate using probably three.
A hot wash for towels and some bedding, a 40degree for most clothes and a delicate one ,very infrequently.
Are all these complicated programmes really necessary?
Also each programme takes about a third longer than in my previous machine.
