The same thing happened to my 86720 yesterday (got stuck with 16 mins to go - then CE code). Luckily I knew what it was because it's happened twice before. It's the motor brushes. I went out this morning and bought new ones (£13.99) from a local independent dealer, and its now working fine again. Though the original brushes lasted 4 or 5 years, the replacements seem to only last 2 years.
It's a fairly easy DIY job - remove the back panel of the washing machine then the 2 bolts that hold the motor. Remove the belt and drop the motor. You should see 2 plastic blocks mounted on the motor with wires connected via spade connectors - the brushes are inside these plastic blocks. Disconnect the wires and remove the 2 screws that hold each block. You should then be able to see the spring loaded carbon brushes poking out from the plastic. The brushes are about 3 or 4cm long when new but when they get down to about 1cm they struggle to maintain contact. Your dealer should either have complete replacement units (about £25 for the pair) or just the carbon bits which you can swap after dismantling the plastic housing.
