Hotpoint Aquarius 1000 De Luxe WM22 - V. noisy and dirty?

Hi All

Have the above model washing machine for a while now but have recently noticed it very noisy when spinning with load. Kind of a banging sound - suspect it's the drum perhaps?

Also maybe in relation the load comes out with black imprints of the cylinder grooves. Nice.

Before ditching it and buying a new one, thought why not see if I fix it. Read most of the answers on here but thought worth checking just to make sure of make and model differences.

Have compiled a checklist:
1. Conrete block
2. Base of Shockers
3. Shock Dampers

Am I in the right area? (probably not, oh look argos catalogue...)

Many thanks.
