Why Your Washer Is Shaking Violently

A washing machine that bangs loudly or moves across the floor during the spin cycle requires immediate attention. Violent vibrations are usually caused by an unbalanced load, unlevel feet, or worn suspension components.

The Mechanics of Spin Balancing

When wet clothes bunch to one side of the drum, the rotating mass becomes off-centre. This creates massive centrifugal force. The machine relies on heavy concrete blocks, suspension springs, and shock absorbers to counteract this force. If the load is too small to distribute evenly, or if the suspension is worn, the machine will shake violently.

Common causes

  • Uneven or tangled load distribution
  • Machine not sitting level on the floor
  • Transit bolts not removed after installation
  • Overloaded drum exceeding weight limits
  • Worn shock absorbers or suspension springs
  • Damaged or collapsed drum bearings

Safety warning

If a machine shakes violently enough to walk across the floor, it can pull its water inlet hoses loose from the wall, causing a severe and rapid flood. Stop the cycle immediately.

When to stop and call a professional

If the machine is perfectly level, the load is balanced, but the inner drum drops significantly when you press upward on it, the suspension or bearings have failed and require professional repair.

Frequently asked questions

Can I use the machine while it's shaking?

No. Violent shaking can cause severe internal damage, crack the outer tub, or pull the water hoses out of the wall. Stop the cycle immediately and investigate the cause.

How do I level the machine?

Use a spirit level on the top lid. Adjust the threaded feet at the bottom corners by turning them clockwise or anti-clockwise until the machine is perfectly stable, then tighten the locking nuts.

What's that grinding sound?

A loud grinding or roaring noise during the spin cycle almost always indicates that the main drum bearings have collapsed. This is a major repair that requires an engineer.

Will this damage my clothes?

The shaking itself won't damage the clothes, but if the drum is unbalanced because items are tangled tightly together, the intense spin forces can stretch or tear delicate fabrics.
