My ariston cooker is dual stainsteel electric hob and gas oven, 90 cm wide came with a stainless steel back and hood. I cleaned the front of the cooker and all the temp dials washed off. Can i get more or see another model so i can see how the oven works, as the grill is in the oven along with a defroster and a fan oven but i cant use as i dont know how far to turn the dials.
