ariston awd12s dial turning with 13 flashes

Hi all. I own a ariston awd12s margherita 2000 washer dryer. When I’ve switched it on after a minute the dial starts turning and I’ve counted 13 red flashes then it stops flashing and then starts all over again.

My questions are:
what is the error code?
What fault is it saying it’s got?

I have 2 small children and can’t be without a washing machine.
I would be very appreciative of any help.

Thank you kindly in advance 🙂
