Hi..wonder if anyone can help...this machine makes a real loud noise on fast spin,sounds like a jumbo jet trying to land in the back garden...could this be a bra wire or are the bearings or shocks gone...how do i tell if the bearings are gone..also because of the vibrations the black pipe that goes to the pump fell off,in this pipe was a platic ball,(bigger than a golf ball)should that be in there?....
