Smeg Dishwasher DC122W - when I open the door and turn it on it makes a noise as if it is trying to do a part of the cycle but is stuck. It shouldnt be working at all until I shut the door and make the programme selections and press start. I cant get it to stop doing this or get it to change onto another programme no matter which buttons or combination of buttons I press. Does anyone have a manual? Or know what it is wrong with this dishwasher? Thanks
