A Kenmore Elite washing machine should operate with some normal sounds, including water filling, draining, tumbling, and the motor changing speed. However, a persistent knocking noise is different. If the washer begins banging, thumping, or knocking during the wash or spin cycle, the cause may involve the suspension system, drum bearings, or another mechanical component.
Ignoring the noise can allow a relatively manageable problem to become more expensive. A loose or worn component can place additional stress on the tub, motor, belt, and other parts. Identifying when and how the noise occurs can help a technician determine where to start the inspection.
When Does the Knocking Noise Occur?
The timing of the noise provides useful diagnostic information. If the washer knocks mainly during high-speed spinning, an unstable tub or suspension problem may be involved. Kenmore Elite washers use shock absorbers to control tub movement. When these components become worn, the tub can move excessively and strike surrounding parts. A knocking sound that appears when the washer changes from a slower speed to a faster spin can also indicate that the suspension is no longer controlling movement properly. The problem may become especially noticeable with heavier loads. If the noise continues throughout the wash cycle and seems connected to drum rotation, the drum bearing deserves attention. A damaged bearing can produce grinding, rumbling, knocking, or other unusual mechanical sounds.Worn Shock Absorbers Can Cause Heavy Banging
Shock absorbers are designed to reduce movement of the washer tub. Over time, they can weaken or become damaged. When that happens, the tub may bounce or shift more than it should. You may notice several symptoms:- Knocking or banging during spin
- Excessive tub movement
- The washer shaking across the floor
- Uneven loads becoming difficult to balance
- Strong vibration at higher spin speeds
