My ideal classic boiler will ignite when i turn it on and it will burn for about 5 mins and then stop. We have checked the thermistor and the pipes around the valve and changed the circuit board and ive checked the propeller and bled it for airlock. So what shall i do?
Are you sure the pump is actually pumping??? Although the pump is running it may not be pumping or partially pumping. This will cause the boiler to go into overheat
