My Nautlilus has stopped cleaning or spraying sufficiently. everything gets wet and partially cleaned but there seems to be a lack of either pressure or quantity of spray in that the little soap packets do not disolove completely as well. i've checked the inlet valve via ohm tester and it passes. i've checked the water feed and its clear-water pressure very good. the float was very dirty but i cleaned it and the switch seems to be working. the sprayer assembly moves freely and does not appear clogged although i cannot know if it is fully extending during wash and there appears to be no cause for it to be blocked or impeded from within the washer. the machine sounds like its going thru the cycles. where do i look next and how do i test?

thanks
