We had a power cut today when we were both out at work and when I tried to turn on our Electrolux EHI8742FOK induction hob it beeps very briefly, the heat setting displays flash, then the the heat setting displays light up one at a time from left to right showing the number 18, then the clock display shows 18 then 14 then it shuts down. All of that happens in about 5 seconds. There are no error codes shown and I have tried to power it off for 5 mins but it still won’t work. Anyone got any ideas please?
