Thats a difficult one for me to advise you on. It just might be the modulation device is not operating or the control function. It will need dynamic testing for control voltages etc.

Be aware that your boiler is getting a bit old now and they are luckily not very common so you may need a bit of an enthusiast engineer to repair it as it might need a bit of original thought! Many people will say get a new boiler although I expect that the fault is actually something very simple.
