how can i fix indesit evelution 1600 we16 fault code f-12?

I had the same problem the machine just kept filling with water. Take the front cover off and make sure there are no foriegn objects in the filter positioned bottom left hand side of machine. After turn water off to washer then start as normal let it go through cycle until command -H20 appears on screen turn on taps and once the code disappears turn the supply off again it should start resuming cycle once stopped run drain seqaunce 2mins then run spin cycle 10 mins. The code f12 lights 1&2, communication error. Turn water back on and run program 9 30min wash. I Hope it resets your machine and you have the same luck as I did.
