Is this the knocking noise your washer was making in spin mode? If so, you have a faulty motor.

The problem is likely with the motor switch which is the brown plastic part that the wiring harness plugs into. These motors and their switches are not normally serviceable however I have repaired them. If your very handy, you could attempt this repair. There are no new replacement motors of this type. There is a new type of replacement clutchless motor for this washer which comes as a kit that includes a required relay, capacitor and new wiring harness. The problem with the washer is that it won't operate in low speed. The first part of the spin cycle is in low speed. The motor always starts in high speed even when low speed is selected but when the motor comes up to speed it is switched to the low speed winding by the centrifugal switch. Either the switch is bad or the low speed winding is open. The motor then shuts off, it slows down, reconnects the high speed winding and repeats this on/off over and over (thus the knocking sound). This can cause the motor to trip the thermal overload shutting it off completely til it cools off. As a temporary fix, you can wire it to only operate in high speed. A couple inches from the motor wiring harness connector, cut the blue wire and the white wire. Strip the two blue wires and only the white wire from the timer. Twist these three together and put a wire nut on it.
