Dimplex SI TE 30 GSHP has stopped working

Hi I’m Mark. We’ve just purchased a lovely Edwardian property that had a substantial renovation 10 years ago including the former owner adding 40 solar panels in a ground array, a Dimplex SI TE 30 GSHP to service 5,000 sqft and underfloor heating with 25 heatmiser thermostats across the property in various rooms and zones. I’m keen to get even more into renewables and I’ve got a range of issues I’m planning on working through to improve efficiency & effectiveness, and prepare for another large extension next year. Finding this forum is great and I hope to be a regular! However my GSHP has just stopped working and it shows the following message on the Dimplex heat manager software: load prim. side block (see attached image) I can’t get a response from Dimplex and the former owner, who is wonderful and stays in touch, has not seen that message before. Would anyone on this forum know what that message means, why it might be affecting the unit working, and what I need to do in order to rectify it quickly? It was suggested I turn off the heat pump and turn it back on, which I’ve done, but the message comes back and the heat pump doesn’t operate as expected. My wife’s family are supposed to be coming for Xmas but she has just left to find a warmer place until it’s fixed so I’m not too popular right now! Many thanks for any feedback. Mark

@transparent thanks, I got delayed posting back as I had few other things to juggle and then the site bumped me out.

I think it does already have surge protection although will be getting the whole system reviewed to ensure it’s fit for purpose going forward. See attached photo. EDF is our provider as we are in the South East.

More to follow in the New Year on my exploits and experiences!

Best, Mark
