Our built in microwave (C17UR02NOB) broke again. Error code E1007 again. Purchased march 2021. Magnatron replaced September 2022 under warranty. Here we are July 2024 with a useless piece of junk. These magnatrons don't last long so expect a breakdown every 12-18 months. I have never had a microwave break down on us before, in fact of the 3 previous ones, 1 was sold, The second is in my workshop (to re heat my coffee) And the third one I have brought back in to replace this useless naff. Sorry, neff. Even better naff neff. Probably looking at around £200 to have it repaired. Don't expect appliances of this price to have such a short life. Looking at other reviews I see I am not alone with the magnatron problem on a naff neff. I had never even heard of a magnatron problem untill I bought this. You would think that with this amount of magnatron problems they would have sorted the problem. But as neff like to point out, they are a innovative company. They certainly are, the innovation is in the way they make more money on what was a very expensive appliance in the first place. If you buy one of these, expect high maintenance costs. Have also seen reports about the electrical efficiency of this item & it doesn't make good reading .
