canalsiderenovation Posted December 17, 2022 Share Posted December 17, 2022 Can anyone help. There is an error showing on our heat pump control. Link to comment Share on other sites More sharing options...
canalsiderenovation Posted December 17, 2022 Author Share Posted December 17, 2022 I think the heating is working but I'm not sure the hot water is. Any idiot proof guidance to try and solve this please? Link to comment Share on other sites More sharing options...
Kelvin Posted December 17, 2022 Share Posted December 17, 2022 An E912 error means it’s detecting flow when it thinks it shouldn’t. It’s likely that a relay or maybe a valve is stuck open. I think you can test this from within the control panel? Link to comment Share on other sites More sharing options...

I've found the flow thingy but no idea what else I should be looking at. Link to comment Share on other sites More sharing options...
Kelvin Posted December 17, 2022 Share Posted December 17, 2022 That shows you what the flow rate is when it’s running. It could be a relay in the Samsung controller box causing it. A neighbour had exactly the same issue which required a new PCB. In his case I powered the controller box off then on and the main circulating pump immediately started running which it shouldn’t do if there’s no call for heat. The relay in the controller box was stuck closed. I’m pretty sure there’s a diagnostic test you can do that manually turns the pumps on and off. If you turn it off and the pump still runs then it’s likely a fault in the controller box. Call Freedom Pumps as they are generally very helpful. 1 Link to comment Share on other sites More sharing options...

When I go to turn the hot water on, everything lights up and sort of kicks in briefly then goes off! Can't even get an engineer either. Link to comment Share on other sites More sharing options...
Kelvin Posted December 17, 2022 Share Posted December 17, 2022 Here’s the self test operation I mentioned. You can switch each component on and off manually to test that each component is working. If it is the relay that’s stuck closed then it’s likely that when you switch the water pump on then off you might find that it’s still runs.

Kelvin Posted December 17, 2022 Share Posted December 17, 2022 (edited) I did some more googling and came across this thread on here. Same error state you’re experiencing and same potential cause I’ve seen before with my neighbour’s system. Just keep in mind that if you decide to open this up it’s a live board so you need to switch it off. If you’re not confident then don’t touch it and try and get someone out.

Thanks I tested those and the water pump comes on, albeit only briefly then off again. Others seem to be fine too. VID_20221217_095143.mp4 Link to comment Share on other sites More sharing options...

canalsiderenovation Posted December 17, 2022 Author Share Posted December 17, 2022 Ok here is what I've found on video - are these red lights normal? Taped things, turned power back on and water on and pump initially came on then went off so for some reason we can't get the ASHP to do water. Pic afterwards.

ProDave Posted December 17, 2022 Share Posted December 17, 2022 Can you confirm it works normally in space heating mode, i.e. the pump continues to run and the house is warm, and your problem is only when trying to heat the hot water tank?

Yes heating seems to work fine, because house was warm this morning. When I put the stats up this happens so I presume it's just the water. So far tried two engineers and no one can come out before Xmas, unfortunately getting anyone in our area with HP knowledge is difficult and hell (or our house!) would freeze before I'd let the plumber back who did the plumbing and installation (signed off by Alto who are helpfully only open M-F). Actually scrap that no heating either lights turn on but ASHP isn't working outside. Brilliant no heating or hot water.

canalsiderenovation Posted December 17, 2022 Author Share Posted December 17, 2022 (edited) So the actual HP unit outside isn't working even when we put the stats up, rooms show calling for heat but pump unit isn't working outside. So no heating or hot water - bloody hell. Just what we need. Edited December 17, 2022 by canalsiderenovation Link to comment Share on other sites More sharing options...
canalsiderenovation Posted December 17, 2022 Author Share Posted December 17, 2022 Just spoke to someone who can't come out but he suggested the filter. I recall them showing us this so we are just going to try and check this. Does this bit look like the filter? And next question, if we need to take I presume we need to turn something off before removing the filter. Any suggestion? Or this pic below where you can see what I think is the filter and the black handle. Link to comment Share on other sites More sharing options...
canalsiderenovation Posted December 17, 2022 Author Share Posted December 17, 2022 Only a year ago did Alto come out and do a warranty repair and noted the following on the job notes; Flow switch and the cable replaced. Filter was clogged so cleaned it. Presume was down to 0. Filling loop was not working so had it replaced to top up pressure. Flow rates at 26 l/m. One of the filling set valve was half open.

ProDave Posted December 17, 2022 Share Posted December 17, 2022 I think the filter is inside the ASHP perhaps if there is anyone that knows this model could comment. Is is still in warranty? Can you play on the fact you have no heating in this freezing weather to get them to come on an emergency call? Link to comment Share on other sites More sharing options...

I believe it was 12 months warranty and they came out a year ago when it was under warranty and we had the exact same issue! I have just found the email and it was the same error then and they replaced the flow switch and cable. They aren't open at the weekend. It's just over a year to the date I emailed with the same issue with the notes I mentioned above. Seems either way we are stuck this weekend with no heating or hot water.

canalsiderenovation Posted December 17, 2022 Author Share Posted December 17, 2022 (edited) I'm sure it's this Trouble is we don't want to do this incase we end up with water spewing everywhere as I'm sure you must need to isolate something first.

Doesn't the HW tank have an immersion heater as a backup? For heating you could get some cheap electric heaters. 1 Link to comment Share on other sites More sharing options...

Turning the handle off should shut it off. If you don't want to tackle it yourself you just need a plumber that can follow that simple instruction, not a specialist heat pump plumber. 1 Link to comment Share on other sites More sharing options...

HughF Posted December 17, 2022 Share Posted December 17, 2022 If it’s a freedom heatpumps install, it will use a filter ball instead of a maganaclean or similar. Plenty of information from Graham hendra on YouTube on how to clean these. Link to comment Share on other sites More sharing options...

It's Alto rather than Freedom but I think it's the same I've got the videos so I feel OK checking the filter and I vaguely recall the engineer coming out last time doing this but I don't know if we need to do anything to make sure we don't get lots of water coming out when we undo the filter - that's the bit I'm worried about! If I unscrew something and we end up with a house full of water! Edited December 17, 2022 by canalsiderenovation Link to comment Share on other sites More sharing options...
