Our smeg SA9065xs has power to it as the clock is working but the oven has stopped, the igniters are also working on the stove top. There is a small "A" flashing on the display and as I cannot under stand how to programm the oven I am wondering if this "A" has anything to do wish the oven not functioning anymore. I hope you can help or do I need a technician to come and see it?
