Indesit Evolution 1200 we12
Its coming up f 9 on the display and some times f 12
This is a fault code but I don't know what it is telling me is faulty?
Any ideas please?

I have had a look and all the wires are plugged in and every thing looks
okay inside.
the machine is only 2 years old.
I phoned Indesit and they were useless, they said' it means there is a
fault' yes I know that but what fault? ' we could send an engineer out
at £70 if you like'
