Hi,
I've an ATAG combi boiler. It was working fine till yesterday. But now there is no hot water in the taps. I can see in the display that the flame comes up for few seconds and then the DHW pump overrun message comes. The message stays there as long as I keep the tap open. No hot water though. Tried resetting the appliance, but no luck. Any idea how to fix. Picture attached
