According to their senior technician, we should not necessarily expect our top of the range Neff Hide and Slide oven to last more than 2 years!! It has been confirmed (verbally) by 3 separate NEFF engineers that the heat from the oven has damaged the control unit leading to an intermittent fault. These engineers have all also confirmed (verbally) that it's a very common problem with the Hide and Slide ovens. All 3 engineers have confirmed that when the control unit is replaced, the download of the new software regularly causes the control unit to crash, which destroys the control unit and, in the process of doing so, damages the oven's power module So, we had a functioning oven with an intermittent fault. After 3 separate NEFF engineer visits we now have an oven that won't even switch on. The original control panel (that functioned but had been damaged by the heat from the oven) was not fixed but moreover is now dead because the NEFF software update crashed. Neff want £339 to replace the control unit that was damaged by their software crash AND £350 to £500 to replace the power module that was damaged when their software update crashed. Customer service is poor. Scripted repetition. Staff who don't listen (or simply don't have the training to understand), talk over you and force you off the phone. Told to email an anonymous email address. Going into our second month without an oven. Engineers great. Try their best but product is not fit for purpose, software is faulty and they're poorly supported by NEFF
