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
