Hot water suddenly gone off with the above boiler (14 months old). Gone through the fault finding and discovered the boiler pressure was 0, even though no fault code was been shown (the boiler would fire for a few seconds then cut off). Refilled the system and restarted, this is when l9 showed up. Turned off and back on, now shows three horizontal lines. Checked manual, heat exchanger won't refire until under 50c. Left to cool, restarted,fired for a few seconds, then l9. Turn off, retry and back to 3 lines. Thinking the dry heat thermistor or is it something silly? R
