You will probably find that the two shock absorbers supporting the underside of the drum are worn. This will allow the slightest imbalance to be shown up during the spin cycle.
I don't know whether yours are "friction" or "hydraulic", either way diy repairs to them rarely work.
Log on to 'www.espares.co.uk' and see if they have parts. They're not cheap, but it's cheaper than a new machine.
