Towards the end of the rinse cycle the machine began making a great deal of noise, so my wife shut it off and called me. I found that the noise occurred as it was trying to agitate (or spin?). I put it on the gentle cycle and it did agitate, but quite noisily. It never seemed to spin, but I didn't try very long because of the noise. After removing the clothes, I advanced it to drain and was able to get it to drain, although even that process sounded noisier than usual. Please advise.
