My heating and hot water do not work and “A03” is flashing?

Hello, I have recently come across a problem with my Chaffoteaux & Mary, where neither my boiler nor heating work. It was working perfectly fine the night before but then shut down all of a sudden, and it flashes “A03”. Unfortunately I do not know which model it is, please help.
