An obvious start would be to buy an LG Washing Machine which boasts Triple A ratings for energy, spin and noise levels. Innovative LG DirectDrive Motor technology reduces the number of moving parts inside your appliance and thus reduces the noise generated (as well as extending its life due to less wear and tear).When installing your washing machine, make sure it stands on a level surface and check regularly. An unbalanced unit may shift location or bump around, increasing noise output. Placing anti-vibration pads underneath your washing machine can also help reduce noise.
