Kenmore Washing Machine: excessive vibration and knocking
What is this symptom?
If your Kenmore washing machine is experiencing excessive vibration and knocking during the wash or spin cycles, it could be due to an unbalanced load, worn shock absorbers, or damaged suspension components. This issue can cause the machine to move, rock, or make loud banging noises, disrupting your laundry routine.
Important Tips for Kenmore Models
- Kenmore guidance emphasizes unbalanced loads and provides specific part listings for suspension springs, drain pump, and leveling adjustments as common fixes.
Possible Causes
Unbalanced laundry load
How to Identify: Vibration and knocking occurs mainly when heavy or bulky items are washed alone and feels uneven; redistributing clothes reduces symptoms
Part: Drum/Laundry load distribution
Worn or broken shock absorbers
How to Identify: Excessive vibration/knocking especially during spin despite correct load and level; visual inspection shows worn/damaged shocks
Part: Shock absorbers
Broken or weakened suspension rods/springs
How to Identify: Machine shakes violently with repeated knocks; inspection reveals broken rods/springs
Part: Suspension rods or springs
Worn snubber ring/pad or balance ring with leaked fluid
How to Identify: Machine vibrates even with balanced load/level; inspection shows worn or fluid‑loss in balance ring or degraded snubber parts
Part: Snubber ring/pad, balance ring
Loose or damaged drain pump or other internal parts
How to Identify: Vibration associated specifically with drain cycle and possible rattling noises; debris seen in pump
Part: Drain pump
Transmission or drum bearing wear
How to Identify: Vibration accompanied by grinding noise; drum feels loose when rotated by hand
Part: Transmission/drum bearings
DIY Solutions
Rebalance laundry load and avoid overloading
- Stop the machine and open the door
- Redistribute clothes evenly around the drum
- Avoid washing single heavy items or, if needed, balance them with other items
- Restart cycle and check vibration
Level the washer
- Unplug machine for safety
- Use spirit level on top of washer to check level front‑to‑back and side‑to‑side
- Adjust each leveling foot by turning clockwise/counterclockwise until balanced
- Check stability and tighten lock nuts
Inspect and replace shock absorbers or suspension rods/springs
- Disconnect power and water
- Remove access panels to reach suspension/shock components
- Visually inspect for broken, worn, or detached parts
- Remove and replace faulty shock absorbers or rods/springs with correct parts
- Reassemble and test machine
