What I might do sometime is photo all my system and you can hopefully tell me if I have the necessary parts fitted. many thanks to all

Hi all surely if the pump isn’t quick enough it would error all the time and not just when there on the time setting?

The pump which is just outside near ashp is set to lowest constant pressure curve, do you think it needs to be on highest constant pressure curve? As Grundfos did say because I have a mix of ufh and radiators to put on constant instead of proportional.

What is the creamy/white colour cylinder please?

Mine do have motorised valves. It’s getting quite complicated to fix, thought it might not be to taxing lol. how can it be valves or what others have said it it’s ok if you leave hw and heating on all the Time. As soon as I put hw on the timer I get the error. It’s not straight away, it varies like say 12 hours or more m????

Yes a pump that sits on the ufh manifold. no filter in the system. I think I’m going to check if there is one in the ashp outside itself. whats a buffer tank in the system. I do have 2 small tanks? Not sure what there for. I think one is to pressurises the system but not sure on other. Will get photos in a bit.

I have towel radiators with no thermostatic valves on? I have 4 radiators all with thermostats on them and 2 towel radiators with no thermostats on

Do the Dream have a filter in the ashp? I don’t have one indoors. I’m wondering if it’s clogged? thanks

Hi it’s a Dream ESDAW-12.5KH-1PH. i forgot to add this info, if you leave the heating timer on and the hot water timer on then I never get the error. When I had the heating on a timer then this is when I seemed to get the error but not when I had the hot water on a timer but all of a sudden I get the error now when I put the hot water on the timer. Hope someone can help? Thanks

Please help, I have ashp running under floor heating downstairs and radiators upstairs and I get an EE-03 error which is a flow pressure error. It’s annoying when you go out or over night it has errored out.ThanksIan
