Hoover washer/dryer rattling/incredibly loud

[Slackerpop]

We’ve just had a brand new integrated Hoover washer/dryer installed and when it’s spinning at its maximum speed it’s unbelievably loud and makes all sorts of banging noises. See videos below. 
 

Does anyone have any thoughts on what could be causing this?! Is it potentially faulty??

Any help would be greatly appreciated!

Hi. To be honest it doesn't look installed properly. It looks high, is is stood on something other than the floor? Also there should be fixing brackets of some type to jam the washer between floor and worktop. Carefully examine the fitting instructions. The whole thing is loose and unsecured so will move about on spin.
