Hi, I have a Zanussi ZDT 6053 integrated dishwasher. When i turn the power on, the 60 degree normal wash light is illuminated. However, the program selection button willl not change the setting to any other program and it will not wash when the door is closed. I have tried turning off for 24 hours to see if it will reset it but to no avail. Can anyone suggest what the problem might be? Many Thanks Ian
