Sorry for not knowing model. Bought new July 2005. Knob has two sections - Whites and Casuals. Whites always goes thru the whole cycle. But the casual cycle will stop mid-cycle in the washing phase. I have to push the knob in and advance it a couple clicks, pull the knob out and it continues. Used to happen occasionally, then would stop in the same place every time. Lately, it's stopping twice. Seems odd that it's only on the Casuals - makes me think it's the knob mechanism. Any ideas? Thanks!
