Washing machine makes a noise and vibrates excessively when pressed: a plumber shares 5 little-known explanations
In a tragic turn of events, a former participant of the Russian reality show 'Dom-2' was found dead in Nizhny Novgorod, Russia. [1] While we extend our condolences to the family, we shift our focus to a less sombre, but equally important, topic: addressing noise and vibration issues in washing machines.
Overlooked transport bolts, used during shipping to stabilise the machine's tub, are a common culprit for loud banging and vibration. These bolts are located on the rear panel of the washing machine. [2] Neglecting to remove and replace them can potentially lead to the washing machine failing at high spin speeds, causing further issues. After removal of transport bolts, plastic plugs from the kit should be inserted into the holes. [3]
However, washing machine vibration and noise issues often stem from several key causes. Beyond overlooked transport bolts, troubleshooting may involve:
- Uneven installation or leveling: If the machine is not perfectly level on a stable, even surface, it can vibrate excessively even when empty. Check that the feet are properly adjusted and that the floor beneath is flat and firm. [4]
- Worn or damaged shock absorbers: These components dampen the drum's movement during spin cycles. Over time they wear out, causing banging or excessive shaking. Inspect shock absorbers for wear, cracks, or weakness and replace if needed. [5]
- Loose or damaged drum components: Foreign objects like coins trapped between the drum and tub can cause rattling and banging noises. Additionally, loose bolts or damaged drum bearings cause grinding, rumbling, or knocking sounds. [5]
- Blocked or malfunctioning drain pump: Clicking or buzzing noises during draining often indicate a clogged drain pump due to lint, detergent residue, or small items blocking water flow. Cleaning the pump can resolve these issues. [6]
- Worn bearings or internal mechanical faults: Grinding, knocking, or clicking noises may point to worn drum bearings or broken gear teeth within the machine. These require careful inspection and typically professional repair. [6]
- Motor or drive issues: Humming, buzzing, or whining noises could indicate motor strain or electrical problems. Restricted or faulty motors might need replacement or servicing. [6]
- Unbalanced or overloaded washing loads: Unequal weight distribution in the drum during cycles, especially the spin cycle, can cause intense vibration and shaking. [7]
Systematic troubleshooting steps include:
- Verify the washing machine is on a level, stable surface; use a spirit level and adjust feet accordingly.
- Inspect and replace worn shock absorbers or dampers.
- Remove any foreign objects from the drum and check for loose bolts.
- Clean the drain pump filter and clear blockages.
- Listen carefully for signs of worn bearings or broken internal parts and seek professional repairs if suspected.
- Avoid overloading or uneven loads in the drum.
Addressing these issues usually reduces vibration and noise significantly beyond simply removing the transport bolts used during shipping. [8]
Moreover, using anti-vibration pads can help reduce vibration, especially for floors with laminate. They can increase the lifespan of the washing machine and make its operation quieter. [9]
Lastly, issues with the power filter can cause noise and pose a risk of fire or electric shock. [10] To remove transport bolts, use a wrench or screwdriver by turning counterclockwise. [2]
By being proactive in addressing these issues, you can ensure a quieter, more efficient washing machine operation, saving you from unnecessary repairs and potential accidents.

The home-improvement task of inspecting and replacing worn shock absorbers within a washing machine can help diminish excessive vibration and noise during spin cycles. [5] To prolong the lifespan of a home-and-garden appliance and experience quieter operation, consider using anti-vibration pads, especially for floors with laminate. [9]
