Vectra S2 pump problem

greg2702 · Oct 31, 2025

I woke up this morning to my return pump restarting every 30 seconds. After a bit of trouble shooting, the pump appears to run ok at lower speed/power, but when to ramps up it cuts out and restarts. When it cuts out the dial on the controller flashes once orange.

I’m wondering is this a power supply issue or the actual pump/controller?

The pump is a Vectra S2

It sounds like a controller issue.

I think you’re right!

I tested the power supply and was still good for 32v. After I posted the pump gave up completely and was continually flashing green/orange.

Trip to LFS and all back up and running. Everything seems to have survived
