Hotpoint Aquarius 1000 noisy on spin, likely loose tub weight

The problem

A 12-year-old Hotpoint Aquarius 1000 became very noisy during spin. Small bits of black plastic were found after washing. After initial checks, the machine ran normally empty, but with a small load it developed a knocking noise as spin speed increased.

Likely cause

The strongest diagnosis in the discussion is a loose tub weight/counterweight causing knocking under load during spin. Bearing trouble was checked by the original poster and was reported as seeming normal, so bearings were not supported as the cause.

What fixed it

The advice was to inspect the tub weights/counterweights, which on this type were described as large concrete-style blocks bolted to the tub, typically at the top or bottom. Suggested checks were for movement in the weight or signs such as fine concrete dust. The exact repair carried out was not confirmed in the discussion.

Checks to try

• Bearings checked by the original poster and reported as seeming well
• Machine run without a load and reported as normal
• Machine run with a small load and knocking started as spin speed increased
• Advice to check tub weights/counterweights for looseness, movement or fine concrete dust
