Hi! I am just curious what can cause my Whirlpool washer model # LSB6300PW2 to have certain cycles which wont wash but will fill yet can hear the timer clicking and see the dial moving? I also have one cycle that for the most part work, the normal wash setting fills/washes/aggitates from the heavy duty setting until the light wash setting then doesn't aggitate but hear/see the timer working until it reaches the rinse cycle where it will rinse and spin the clothes until the end of the cycle normally. I have replaced several parts recently like the aggitator dogs, clutch, neutral drain transmission and motor couplings. What could the problem be?
