I have a Whirlpool NAV2330AWW washing machine that won't agitate. During agitation cycle the washer is extremely noisy. The first thing I fixed was a broken idler pulley (the plastic portion had broken away from the metal inner bushing). The motor runs during the agitate portion, but I don't see any movement on the upper portion of the transmission.
Could somebody help me diagnose what may be wrong? If there is some small component inside the transmission that needs to be replaced, I'm all for it. If I need a whole transmission, I doubt that it is economical to repair.
All of the belt pulleys move. The shaft above the transmission going to the agitator doesn't move though. It all works on a spin cycle though.
