Hi, the older Hoover had a problem with the clutch drive seizing.
Sometimes it was caused by the aluminium housing on the gearbox breaking or cracking.
When this happens, the clutch pawl doesn't release the clutch gear properly.
The clutch stays in the locked position and then it wont allow the tub to spin.
Its not often the top bearing fails.
A common sign of gearbox / clutch failure is a brown oily stain spread all over the inside of the cabinet in line with the bottom of the gearbox.
This means that the gearbox has slowly filled with water through a failed gearbox seal and when it gets to this stage, its not an economical repair.
Time for a new washer unfortunately if you can afford to , would always advise to get a Bosch model for reliability ,the 1200 spin ones are around the £250 mark, the 1400 spin models are dearer, but actually they are the same motor in them , its just that at the end of the spin it increases to 1400 rpm (via a small module that's fitted ) for a short while.
