Hi, welcome to Just answer
Please tell me its complete model number
and how old is it ?
It is just over a year old and is SE2641TC2
have you tried it another socket ?
it is not the socket as I said the power comes on once it is switched off and on briefly, all the hob lights flash go through the sequence of 1 - 9 and then the fist two hobs flash 2 and 3 respectively before it goes off again. This has happened 3 times
and there is no error in the display ... right ?
I mean like E1 or E2 etc ?
when it came back on it said 2 3 could that be an error code?
just 2 3 or was there an E in front of them as well ?
OK, the problem is with the control itself that is bad and will need replacement
you can leave this switched off
for few hours
if the problem remains then the control will need replacement
as it is not too old you can contact Smeg and check with them if they can do this under warranty
