Using instructions I found on this forum post I set the current time on the Zanussi oven digital clock. Here I provide my guide on how to do this.
Press the middle button to change the mode on the front panel
Locate the middle button under the clock on the oven front panel. Press it four times (or as many times as necessary) until the red LED beside the clock icon appears (as seen in the following image).
When the LED beside the clock icon lights you can press + or - to set the time
Once in clock set mode (the red LED beside the clock icon is lit) you can press and hold the + or – buttons until the current time is set. The oven I was using had 24 hour time (i.e. PM times are represented by the hours 12-23).
If the markings have worn off your panel the + button is to the right of the middle mode-set button (that you pushed to get into clock-set mode) and the – button is to the left of the mode-set button.
Easy!

Cheers for that. The instruction manual’s not very clear. The internet’s a wonderful thing… :)
Edward. Jan. 4th 2018. did as instructed THANKS
Need help with obtaining manual for oven internet useless
Thanks for taking the time to do this: something annoying me for months sorted in a few seconds. It works on later models too. Easy, as you say,
Thanks so much – my housemate lost the manual and it’s been bugging me for ages.
can set the time but about 2 minutes later the clock goes back to 12.00 flashing light beside the clock and a buzzing noise like a timer going off, what is the problem?????
Either: you have a genuine fault, or you are setting something other than the clock. Check that the LED is lighting up next to the clock symbol before changing the time.
I tried to follow your sound advice but mine has been driving me insane as I can’t get the LED light opposite the clock symbol to go off! I will wait till someone aged about 12 comes here. No doubt they will fix it in a flash!
The gift that keeps on giving. I just set mine after 6 months of the wrong time. Cheers!!!
Brilliant instructions for clock thank you
Thank you- just set it after power cut and looking in vain for instruction manual.
The manuals tell you how to set a timer to start cooking but not how to set the time itself. And my manual is in Greek! Thanks
Thank you!!!!!
I’ve been trying 2 bloody do that 4 3+ months xxxxxxxxx
Thank you so much for taking the trouble to post this. And such clear instructions, too,
One wonders why Zanussi can’t include it in their manual.
Thank you
I have the same 3 button configuration on my 2017 Zanussi oven but no red led and the clock will not reset???
I fiddled for an hour but couldn’t get the buttons to do what they’re supposed to. The only way I could get things to work was by turning the oven off at the wall, then on again. No problem after that.
