Hotpoint aquruis washing machine wont spin

These machines have a common fault. If yours has no visible filter, the filter is in the rubber waste tube, just below the drum.
Most faults on these machines are due to a blockage or build up of sludge and lime scale in this area.
This also affects the pressure switch, which is linked by a plastic tube to the same place! This will cause the machine to stick, and not spin, otr to spin with water in the drum causing vibration.
Firstly check the outlet hose and the plumbing where the outlet goes to for signs of sludge and lime. Unless you have very soft water or a water softener, there will be some! Usually lots!
Clean this out.
Disconnect the machine from the mains and the water supply and pull it into a clear area.
Put a thick cloth on the floor and gently lay the machine on its left hand side, looking from the rear,
Undo the small panel on the back and you will see the black rubber concertina hose, pressure chamber and pump, which are now all easily accessible from the rear and the botom of the machine.
Undo the circlips with a screwdriver and the special plastic clips with a pair of pliers by twisting each part in the opposite direction.
Take the whole hose off. You find a filter and a "ping pong ball" inside this.
Clean it all out as thoroughly as you can. At the same time clean out the plastic pressure chamber and the pump. you might need to use a proprietary limescale remover or vinegar to do this.
You will usually find a few buttons, plastic items, paper, couins and a load of sludge!
Put the whole lot back, The plastic clips slide together with a toothed grip.
The whole job should take about half an hour and the machine will be like new.

Briliant explaining firesign! I just didnt  know how the hell that ping pong got in there.  was gonna use it to play but it had no bounce:) anyway, its all back now and running better than ever(had it secondhand).Many many thanx! Cheers !!
