Samsung E911 intermittent issue

NetDonkey · 2024-12-06T21:32:07Z

Hi all, Been having a trawl through the forums for the E911 and have a few other queries. I have a AE080CXYDEK which was installed back in June and has been working well. Recently, however, we have had a couple of E911 errors which has led me to dig into our install a bit more. Using our MIM i can see the flow is around 7.2-7.4lpm which is almost at the HP's minimum in which the E911 error starts. I have queried our installer (electrician who installed the solar and battery and subsequently subbed the ASHP install out) and it's taking a while to get anywhere. So my queries are as follows: We have a Evosta 3 set to fixed curve regulation mode level3. Is this correct? It looks like the Evosta has been installed upside down but I assume it was done this way due to the flow direct? I can stop it from erroring by only running the heating and within 15 mins of powering on the DHW it trips (subsequently in the last 12hrs I have had both running and it hasn't tripped). Does this narrow down what the issue could be? In another thread, Mars mentioned checking the Y strainer. Is this easy to do as a novice or should I be pushing to get the plumber to come out and check. If it's easy where is it usually located and what does it look like? How happy are other plumbers to come out and diagnose a system they havent put it and is it worth doing this? Thanks!

Just a quick update. It looks like it may be the actual Samsung is broken. Whether it's been caused by the 16 litres of glycol the installer put in for our 12 radiator system or not is still to be seen. Waiting for Samsung to open tomorrow to get them to come out

Just an update to let everyone know that we are now all back up and running after 2 weeks of no heat in the coldest January in a while.

We finally had the installed agree to drain the system and flush everything through. When he was disconnecting the ASHP from the outside flow and return he removed some lagging beside the shut off valves and spotted something he hadn't noticed before. The shut off valves also had filters in them
