A couple of years back we had our kitchen replaced- due to health issues DIY jobs of that size are too much these days.
The appliances are all AEG and have proved to be the most unreliable, but expensive, we've ever owned in 36 years.
So far, the microwave has been repaired three times and on Saturday the mica cover over the wave guide fell out. Never seen that before!
The method of retaining it is a joke, terrible design. Difficult to get at and requires you to bend the mica, which it doesn't like.
Dreadful, our first microwave (a Tricity, bought in about 1980) lasted 17 years and only vent to the tip as it got a bit tatty. Only repair it needed was the drive belt for the turn table- 35p O rings.
The AEG microwave is so unreliable, we've bought a "back up" just in case.
Dishwasher reported a fault code which was nothing to do with the actual fault, several trips by the engineer to fix (we were not paying) and countless parts.
Fridge door seal and plastic cover on shelf failed (we are the type of people who look after things so this was not due to rough handling).
Sad really, the rest of the kitchen is great, a real show piece. I will admit yhe induction hob is a delight to use.
So, avoid AEG like the plague.
