Excessive shaking from washing machine post new floor

[MattHughes]

Hi all,

In desperate need of help. We've just laid a new luxury vinyl floor that we purchased from homebase. They are plastic tiles that fit together just like laminate floor. We've used 3mm underlay that has been laid on top of the old Lino that then sits there a concrete floor.

It's all been laid down well but we've put all the appliances back and now the washing machine is excessively shaking during a spin and at normal wash. It was not like this before when it was on the Lino.
We've levelled the feet and checked with a sprit levels. We can see the floor moving "moving up and down" under the feet but from the research we have done, the flooring shouldn't have made a difference?

Does anyone have any ideas of what is happening here and what we can do? I really don't want to have to take it all up

I think this is better suited to the flooring forum.. Going to post it there..

The washing machine seems to be unbalanced. Can you adjust the back legs with the washing machine in its possition? In my one I can not reach so I can only adjust the legs and then hope that when i put it back it is still balanced.

Hi North,

Thanks for you reply. The washing machine is level, even used a spirit level to ensure it is level. Adjusted the legs to do this, even tried using off cuts in the hope that would help but it is the same result.
