Hopefully there is a NEFF technician out here that can help with this. I bought a NEFF double oven from an auction site that is ex-display. The oven came with a plug on it so I presume it has been in a showroom as a demonstrator. I have wired the oven in but it does not heat up. It does power on and you can set clock and change any of the functions shown in the manual e.g. childlock, clock display, fan duration etc, so I presume that it is in demonstrator/safety mode. The manual for this model I downloaded does not explain how to turn off demo/safety mode. Any help with this would be appreciated
I have known manufacturers disconnect elements for display purposes. You may need to have an engineer in to make sure everything is still connected. Did the oven come with any form of guarantee?
