Dont think you have either of them options on this model. I know what you mean about the instrustion booklet for the waa range its a cheap photocopied booklet. You have to go up to WAE range to get a colour book and complete instructions.
Saying that about 2 years ago I fitted a waa that would do a pre wash when you selected express wash. The customer was not happy when her express wash took half hour longer than a normal wash. 😉
In my opinion the WAA24171 is a superb machine, better than the rest of the WAA range.
If you look at the facia panel it says ‘pre wash’ next to the 60 degree cotton wash.
I suppose the thinking being that there is not alot of point having a ‘pre wash’ on short/ quick washes.
I dont think the ‘rinse hold’ is an option though.
