We had Neff hide and slide oven , integrated fridge, induction hob plus integrated microwave/ combined oven installed over 5 years ago. We've had no problems whatsoever until the other day when the side runner of the hide and slide door cracked which made it difficult to open and close the door. Went online to neffs spares page where its possible to buy every conceivable part for their products at realistic prices plus theres a complete visual brakedown for repairing their products. Ordered the part and received it within 2 days. Easily changed the runner and the door is like new. Cant understand some of the posts regarding taking the door off and cleaning the glass on the oven . Its a dawdle of a job. Plenty of you tube videos available
