I have a WWx223RBW2 BOL washer made in 95. It works fine except when it begins drain/spin it makes a screeching noise, after all the water is out and it continues to spin, the noise stops. I ve taken off the front, it has a new belt. I have narrowed it down to the drain parts of the cycle. I am assuming the noise is coming from the pump. Anyone have any idea how to repair without replacing the pump?
