SLO error after switching to a VS pump

jcrompton · Aug 11, 2024

I recently got a Hayward VS pump - I haven't programmed it yet so it seems to run at low speed a lot. Frequently when I go to my SWG it reports "SLO" and seems to get stuck in that mode unless I turn it off and then back on.
The salt level is approx 3000 - 3100 reported by the SWG and by measuring independantly.

Any thoughts?

What model number pump and SWG are we discussing?

Hayward Tristar 950 Model SP32950VSP and a BlueWorks Model BLH60-A W

As I mentioned above -- even though the error is "SLO" the salt level in the pool is NOT low

I understand what the fault code is --- as I mentioned the salt content is not low

It just seems to happen when this new variable speed pump goes into the slowest mode

Did you read the article? That is mentioned. Turn the cell over so the hump is at the bottom. It may work. Yours is a Hayward clone SWG.

Oh wow - I did NOT see that - I haven't had to do that before (but admitedly I had my prior non-variable pump and SWG on a timer -- where now I am riunning the VSP 24/7 but at longer periods of low speed)

Thank you !! I'll try it!
