We’re house sitting for some friends and they don’t seem to have a manual for their Diplomat ADP 3300 oven. At 5 a.m. Sunday we had a one hour power cut, following which the clock display has been flashing 00:00 and AUTO and does not respond to the buttons being pressed.
Last night I discovered that neither the oven itself nor the fan was working. The hotplates are working fine but you can’t cook pizza on them! 😕
I had the same problem last week after a power cut, and I have no manual to help either.
In the end, I pressed all the buttons down at the same time, and that seemed to re-set it, and from there I was able to set the timer etc.
Try it and see if it works for you! 🙂
