My Kenmore front loader runs out of balance at very high speed. Previous to this it ran fine until my drain pump got plugged with a nickel that broke a blade in the pump. The washer went very imbalanced with the water not drained, very loud knocking/banging. I replaced the pump and the drain works fine now, however the imbalance remains. I've checked the floor mounts and they're solid. The springs and the dashpots on the sides holding the barrel look OK. The machine spins up OK but at very high speed a knocking noise begins and the barrel starts to wobble around. Any thoughts?
Thanks.
