Mum has had the dishwasher for approx 7 years. It was put on 2.50 programme for a hot wash when tried to alter back to 1.15 the programme would not change. There are no strange sounds or flashing error lights flashing.
Thank you Michael I will have to discuss with mum to see what she wants to do.
Thank you for all your help mum has decided not to go ahead with the repair.
