Hi
Jjust been to this washer which was not draining. (blocked filter) cleaned it, it stasrted off ok but after a minute or so, it stops and the top light in the column starts flashing and you are unable to turn the macnine off (except at the plug)
F08, could be press sw, or faulty module but i would check the element 1st, had lots giving this fault if the heater is down to earth, especialy if the sump was full of coins,
