After having another new water pressure sensor to get the boiler working, heating flow isolating valve, heat exchanger and numerous seals to stop a slight leak, I am still without hot water! At £50 + coffee per visit I'm £360 down so far! I need to confirm what needs replacing before I either do it myself or get the boilerman back. Lights 70 and 80 meaning no flame detection. What do I check and how?
