I do not have a manual for this machine but if what you are doing sounds perfect to me and if you are getting good results then I wouldn't change a thing. I can see part of a button over on the right, that starts with an R...and am trying to remember what those buttons are, is it regular for regular agitation and delicate for light agitation maybe?... I do know those were great Maytag's.

Something apparently went wonky with GW's database. I answered this question in much detail weeks ago. There was one other reply that I recall, and the OP followed-up.

Don't know if you know it but the center of the agitator should pull out. It's the lint filter.
It should be cleaned after every load (like the dryer lint trap).

Here's what it looks like.
