We purchased this appliance 4 years ago. The inside has corrosion and caused the brackets that hold up the heating element and glass part above (looks like a plate) on the inside roof to drop off. We have contacted Neff who sent their engineer at a cost of £99 to tell us it is damaged and cannot be repaired. He told me he has only seen this on 15 year old microwaves!
I have found reviews on other sites saying the same thing. Anyone on here had this problem with Neff? Because basically they are saying I have misused it, even though it’s not used everyday as we have a main oven that I prefer due to ease of cleaning.
