an hour? whoa. could it be the yarn?
my bags (Kureyon/220 mix) took 3 to 5 agitation sessions. each session on my washer is about 5 min.
I say start again. put the washer on its lowest water setting, select hot water, and choose the most vigorous agitation. when that agitation stops or slows, gently squeeze the water out of the knitting, and set the washer back to the vigorous agitation (on my washer I turn the dial back) and repeat until it's to your liking.
