have a Zanussi ZBF-360 cooker and every so often the clock
resets to 12:00. At this time, there is a buzzing sound as if it is on
a timer. None of the timers are set and all read 0:00 (ecxept the
clock).
Is this a short circuit?
The 1000uF/10V condensator in the timer unit has to be replaced.
The problem is most likely with the Large Rectangle Grey X2 Capacitor on the clock circuit board.
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. :)
