Hi, the 1/2 is a half load symbol and the wavy lines are no heat.There is no C2/F2 either on this machine, it could be E2 and part of the digit is missing.The half load and no heat is not on this model either.It looks as if the pcb is failing and you have an E2 flood fault.
The pcb is part no 696290726 and it is £116 plus vat and postage.More than likely for the flood fault,there will be water in the lower base behind the silver cover.If so, take off the right side of the appliance and you will see the air break (filler unit.)If you turn the machine on to fill,you will see water bubbling up at the joint with the softener unit.You will need to replace the O ring seals x2.These are part no. 754131307 and you need two at £4 each plus vat and postage.Put the seals on the air break ,push till it locks and the pull up until it fits in the side opening.Hope this helps, All the best.
