Zanussi Ovens - Recent Questions, Troubleshooting & Support
Zanussi Zob 330: The clock resets itself to 12:00 and makes a buzzing sound after about an hour of resetting the clock to the correct time. What could the problem be and how do I fix it??
The problem is most likely with the Large Rectangle Grey X2 Capacitor on the clock circuit board which needs to be replaced by an appliance repair person or electrician.
From my understanding, although they are self-healing, as they are subjected to power surges they deteriorate and allow less and less current through the circuit until they get to a point where there isn't enough current flowing to firmly latch the relay (which is why there is a buzzing from the relay turning on and off quickly).
My clock was also at the point where there wasn't enough power for the timer beeper, so when the beeper went off it would reset the clock after about half a beep. And if the clock was started at 12:00, when it got to 16:08 it would reset as there wasn't enough power to display all those led segments.
I replaced the 1000uF capacitor, which didn't change anything, then replaced the X2 capacitor and now it works perfectly!
Hopefully that is helpful to someone. :)
