Purchased all Neff appliances for new build house, including the Hide & Slide oven, B47CR32NOB/C1. However, after only 3 months & keeping the oven spotless, the oven door has two long streaks inside the glass door which look unsightly. Checking the manual means you need to remove the door, then the glass door panels, all whilst adhering to the constant, 'Warning- Risk of injury'. I contacted customer services who told me that I would need to pay for an engineer call out, even though the oven is only 3 months old, as this wasn't a fault. I beg to differ. If the oven door is so poorly designed that it will need dismantling every 3 months to clean the glass, it is simply not well designed. What a shame & not good experience with customer services.
