Vectra m1 shutting off randomly

[foredababy]

Periodically my return pump will stop pumping water and make a clicking sound like it's trying to start back up. I've taken it apart several times and cleaned it. I'm wondering if it's overheating, gunked up with calcium carbonate precipitate, or other. Anyone have any ideas?

fored,

If you've removed the Volute and cleaned both the impeller and pump body, the Vectra should operate normally. That said, I would recommend contacting us directly if you haven't already for more advanced troubleshooting.
