the hot water is not activated when hot tap is opened on my sime friendly 80E combinatin boiler. The hot water taps were taking some time to activate the boiler. Now they do not come on at all. The central heating is working and the hot water taps work when the central heating is already firing up the boiler.
on page 10 of installation instructions it says that it's caused by 'lack of flame detection. most usually caused by incorrect polarity of the electrical connections'. It sparks, the flames come on but cut out soon after. It's happening to me at this very moment and plumber thinks it's because there's a small water leak.
