FAQs
Why is my Grundfos pump not starting?
Check for power supply issues, blown fuses, or tripped motor protection. Also verify that the control panel or relay is working properly.
Why is my Grundfos pump running but not pumping water?
Possible causes include airlock, dry running, blocked impeller, or closed valves. Bleed air from the system and inspect the suction line.
What causes frequent start/stop cycling in a Grundfos pump?
This can be due to a small pressure tank, leaking check valve, or incorrect pressure settings. Adjust or replace faulty components.
How do I know if my Grundfos pump impeller is blocked?
