hot water supply stopped

Shaunoc

Cold water was off locally for a couple of days, now back on fine.
However hot water taps are not running since, there might be a dribble of warm water for 5 seconds but it stops.
Ideas of how to troubleshoot and purge the block if any?
Heating is danfoss air to water heatpump showing no errors and hot water tank is inbuilt.

Have to tried running the taps closest to source might be just an airlock. Work itself out after ten mins

15 min in and nothing bar a trickle. No gurgling or spluttering sounds

Turnoff the heat pump for a few mins, turn back on and see if it does anything?

Done.

Think I got it. A valve was turned wrong way, from some plumbing emergency last week. Mixup by joiner and plumber! But warm water happy days for morning

Coincidence of cold water supply return timing threw me off
