Hi, Our new cooker Ariston mixed is getting installed. Problem we have is that the top of the door rubs on the side of the cooker when opening and closing. It is sitting on the floor and is leveled using level by adjusting the legs. I do not want to scratch the stainless steel. So can you tell me how to adjust door or the sides witch ever is the one that needs to be moved. Should I be going back to where it was purchased and get them to fix it? Regards and thanks, Joe
