Got an issue with our heat pump keeps throwing up compressor blocked on the interface, this is the 3rd time it’s done it now in the past few days, water pressure is showing 1.2 bar, cleaned strainer out although that wasn’t too bad anyway and magnetic filter also cleaned. reset and then fired up ok last night. woke up this morning with no heating and dhw cycle hasn’t run either and showing the same issue, any ideas?

we had this when it was first installed too but then haven’t had since, this was jan/feb time, only thing I can think of is we have only been using dhw and not heating circuits since then

What does the manual say about this alarm and its likely cause?

Refrigerant gas goes through the compressor, not water, so I don't really see how the compressor could be 'blocked', unless it is poorly written English and 'blocked' means prevented from running.
