@PigletJohn and anyone else who can tell me if my machine has died.
It's a Bosch Classixx 1200 express. It was second hand when I moved into this house 7 years ago. It came with the house which is rented.
I had a load of towels in and as machine finished wash cycle there was a loud rattling noise. I thought something had fallen down behind the machine.
It stopped then began again as machine made noises to drain. I stopped the machine and took the washing out.The drum ran smoothly and there was nothing in it.
Then set it to drain.
Rattling again and machine stopped itself without draining, the reduced iron button lit up and after a minute the machine unlocked.
