in this load here, a little more water would not hurt, but you dont have to go excessive with it...3 or 4 inches more would be fine...
and if the speed selection is Slow Wash/Fast Spin.....all is fine....
there are days/times the brake does not engage, or slips some during agitation....if it happens on occasion, no big deal, but if it starts to happen more, then it may be time for a rebuild of the brake package...
if it comes to that, might as well swap out for a new Neutral Drain kit, and a new motor coupler, inspect your pump at that point.....from there on, your good to go for many more years of washing...
