What are shock absorbers and what do they do
The washing machine shock absorbers connect the drum to the outer frame and are responsible for dampening the vibrations generated during spinning. When they wear out, the washing machine starts to vibrate, move on the floor, and produce metallic noises, especially during high-speed phases.

How to choose the correct shock absorber
-
Force in Newton (N): this is the most important parameter. It must match the original value exactly; a shock absorber with a different force compromises the balance of the drum.
-
Length and attachment: check the resting length (in mm) and the type of fixing pin of the original shock absorber.
-
Brand and model of the washing machine: the model code can be found on the label inside the door; it is essential for identifying the correct spare part.
-
Original code: if visible on the shock absorber to be replaced, search for it directly to find the corresponding original or certified compatible part.
Recommended maintenance
- Always replace shock absorbers in pairs: if one is worn, the other is almost certainly worn to the same extent.
- Periodically check the attachment points to the pins: if the clips or rubber mounts are deteriorated, the shock absorber loses effectiveness even if the body is intact.
- Do not overload the washing machine beyond the indicated capacity: excessive loading significantly accelerates the wear of the shock absorbers.
- Distribute laundry evenly in the drum, especially for heavy items like towels and jeans, to reduce vibrations during spinning.
Common problems and solutions
Washing machine vibrating and moving
Worn shock absorbers or deteriorated fixing rubber mounts; replace both shock absorbers in pairs.
Metallic noises during spinning
The drum hits the frame due to lack of damping; check the shock absorbers immediately before they cause structural damage.
Spinning stops
The washing machine detects excessive imbalance and stops the cycle; often caused by worn shock absorbers or poorly distributed load.
Fluid leaking from shock absorbers
Hydraulic shock absorbers may lose internal fluid; in this case, they should be replaced without attempting repairs.
Quick FAQs
Is it necessary to replace both shock absorbers together?
Yes, it is always advisable to replace them in pairs. Even if only one appears visibly damaged, the other has likely undergone the same stress and tends to fail shortly after. Replacing them together ensures even drum balance.
How do I check the force in Newton of the original shock absorber?
The Newton value is usually printed on the body of the shock absorber or listed in the washing machine's instruction manual. Alternatively, you can search for it on the manufacturer's website by entering the washing machine model code.
Can I install the shock absorber myself?
The replacement is technically accessible to those familiar with home repairs: it requires disassembling the back or side panel of the washing machine, removing the fixing pins, and installing the new shock absorber. If in doubt, consult a qualified technician.
