Hi, for the third time in 5 months we've had heating but no hot water. It lasts for a while, say 24 hours, then the hot water returns. We've noticed smaller events too, several times where there is no hot water but returns after a couple of minutes. When it happens the boiler does not show that hot water is being called for when a hot tap is turn on.
Boiler approx 8 years old. Serviced annually though we missed first two years and so warranty is out. Full strip down service in January'24 and the flow sensor was also replaced as this was the main suspect for the issue. But it's occurred again last weekend. Also powerflushed approx 12months ago.
Can anyone suggest what the issue might be?
