I have a Potterton Suprima 60L and it has developed a problem. The system works fine when either heating water or the central heating but does not do both at the same time. After a few minutes of firing I get the green flashing light.
Checked the system for air and bled radiators. Got a plumber out who replaced the pump, checked the 3 port valve head and flushed the system but still has not resolved the problem.
Anyone have any ideas?
