I have some questions:

When was the boiler installed?

House or flat?

Could you estimate the date that the problem started?

What is the make and model or the boiler, and the programmer, and the thermostat?

Good evening, I haven't heard back from you so I can provide only a general answer.

A very common point of failure in heating systems is a MZV (motorised zone valve). If you have a system boiler then you probably have at least one MZV. These have three main components that can easily become defective, so it's often best to start the investigation there. Let me know if you need any guidance with that.
