Hello all this Maytag washer that I have model number lat9306aae here lately after its done washing and begins to spin sometimes the agitator doesn't spin with the basket it like slips and when I shut it off and turn it back on its fine but does it again during the last spin and I checked the belts and they seem to be ok.So what may be causing it to slip and also once everything is done and I try to move the agitator it makes a small banging noise.
