Donkeydarts Posted November 17, 2021 Share Posted November 17, 2021 (edited) Dear All, After your help again and you were a great help last month. My Kingspan Aeromax ASHP has developed another fault, this time with fault code 9 flashing on the box. In the manual this says it’s a flow switch error/pump problem. I’ve looked on other threads on this forum and someone else said they changed the flow switch which fixed the problem. Can anyone tell me where the flow switch is located inside the ASHP unit if it is inside and also if anyone has any other suggestions on how to fix it other than getting a compete new system as this one is really p!ssing me off now! The system is about 8-9 years old now so I guess things will start to go wrong with it. For info when I switch the system off/on at the isolator it seems to clear the problem but then an hour or so later it comes back. thanks again Edited November 17, 2021 by Donkeydarts Addition to text Link to comment Share on other sites More sharing options...
Donkeydarts Posted November 17, 2021 Author Share Posted November 17, 2021 Is this the sensor that could be causing the issue? Link to comment Share on other sites More sharing options...
