not spinning, will agitate

Hi.

TIA for any ideas.

My washer will not spin, but does agitate. The water drains from the tub and the timer continues through the cycle. It sounds like there is a hum during the spin part of the cycle.

I just purchased this rather old machine from my landlord who said that it was working before he put it in his basement, so the spin cycle stopped working either while it was sitting in the basement, or during the move into my apartment.

Thanks again,
Kirsten
