My core15 pump keeps turning on and off repeatedly ?

What error code are you getting? Volt? My guess is a bad power supply.

I bought an aftermarket one off Amazon for cheap. You can use AI (Grok Chatgpt) to source a compatible replacement.

no error. its say ok on the top right of the tile.

You can try cleaning the pump to see if anything is obstructing it. In my experience, pump cycling was due to a faulty power supply. I have also observed the pump output fluctuating, which was a power supply issue.

Amazon power supplies are $20 or less, and you may be able to get one by tomorrow or Monday.

COR15 does not have a separate power supply. It runs exclusively through 1link. It seems like you have several threads asking about similar/same/related issues. I suggest you keep it in one thread so its easier to follow and trouble shoot. Another option is to go to the neptune systems forums and ask there since they will like be better suited to answer your neptune related questions.

One other thing, the COR pump is programable so double check the tile setting to see if its set at a constant flow or programmed to fluctuate giving you the impression its turning on and off.

You're right. I thought it was stand alone. Thanks for the info.
