My 11 month old LG washing machine has started making this noise when spinning some light loads. Don't really hear it much on heavy loads.
I have an engineer booked in for next week to look at it.
Out of curiosity, I opened the coin trap door cover at the front and noticed around 5 or 6 small pieces of concrete and a little powdery residue. Wish I had a picture.
I believe the issue is caused by the the concrete block at the front of the suspection legs, though I thought its the suspension.
On top speed, the sounds is almost not there and its as smooth as anything but I don't see why I should live with a noise like this so am getting it looked at. Also noticed when putting a light load in the machine like a sheet and selecting SPIN only 1400RPM. The machine spins to only 800RPM and its never unbalanced. I saw a Samsung do this on Youtube.
I do like LG that's why I'm not looking for anything else, but would be interested if someone could view this video and feedback the possible noise. Its not the cabinet and nothing to do with being unbalanced as it does it when the drum is hardly moving and when the drum is really shaking, the noise is not really there.
