Hello,
My Grundfos pump is constantly running. Even with heating and water off, still runs! Heating and hot water is fine and the boiler itself turns on and off when it should. It’s just the pump which never stops. It’s really noisy too. I have uploaded a pic of the pump. I have already bled it. I have a video of the noises it is making but can’t upload! I have taken pictures of the other ‘parts.’ Like I say, everything is working as normal but the pump will not turn off!
