Switch Off Power to washing machine and unplug.
Gain access to rear of machine. Looking into the back of machine, to the lower left of the driven drum wheel (large one), see a small plastic bottle with a rubber tube leading from it and going behind the wheel, up to a round plastic unit situated in the top corner of the machine body.
Remove the plastic bottle by pulling it from it's seating. Remove rubber pipe from bottle.
Check bottle for build up of scum and clean out thoroughly. Clean out the hole where the bottle fits into the back of the drum. Blow, very gently, up the rubber pipe and note if you hear a clicking (switching) noise. Replace the bottle (press fit) and reconnect the rubber pipe (making sure there is clearance between it and the wheel/belt.
Replace covers, restore power and give it a try!
This is a common fault on this machine, the build up of scum in the bottle prevents the vacuum switch from operating, with water induced pressure, and doesn't make the spin circuit. The machines 'mind' thinks it is still full of water.
