Hi all,
I have a Grundfos pump which seems to be struggling to start on its own. Yesterday I noticed the house wasn’t heating up very quickly and as I had the same issue about a year ago, went straight to the pump. I opened the valve and the spinner wasn’t spinning. Whilst calling for heat, I used my screwdriver to turn the spinner either way and it still didn’t start spinning. After some time I realised I needed to push the spinner into the pump for it to start catching to then start spinning?! Eventually after a few attempts, it maintained spinning and seemed to be operating (at least to some degree). This morning after the heating was off overnight, the same issue has happened. Do I need a new pump or is there a part I can replace to save cost? Thanks in advance. Chris
