SWCG No Flow Error

Good morning everyone, I don’t think I these two things are related but mentioning them for completeness. We had some storms roll through Wednesday night and while we didn’t lose power the lights flickered a couple of times. We went out to swim Thursday afternoon and I noticed the pool was a little cloudy. No one else noticed but I look at it every day so I notice subtle difference. I grabbed my kit and saw the my FC was 0 and my CC was at 0.5. I checked the salt cell and the screen was “screwed up”. Best way to describe it. It looked like it was in some odd state, all the warnings were displayed and the numerical display had random lines displayed, nothing resembling letters or numbers for any type of error code. I killed the power and restarted everything and it all came back online and appeared to be working (cell on, flow, etc.). We were running the heater so the pump was in a higher speed. I grabbed two pucks and put them into the skimmer and went driving around looking for liquid bleach (Walmart had some) I picked some up and got my chlorine levels back up, retested and was at 5 and 0.5. This morning everything looks good, cloudiness gone, I haven’t checked my levels yet but I will. I checked the pool equipment and salt cell to make sure that “screwed up” state (should have taken a pic of it) wasn’t being displayed. The salt cell looked normal except my no flow light was on. I did some trial and error and noticed that I need to run my pump at 1700+ rpms now for the salt cell to register flow, I have had the pool for a little over a year and had previously dialed it in to 1400 rpms as the min speed for the salt cell to register flow.

Any ideas what may have caused the sudden need for higher speed pump to register flow? Everything else about the salt cell seems to be working, no warnings, tiny bubbles coming from my returns when I turn the SWCG on, etc.

Anyone else encounter the need to continually raise the vs pump to ensure flow to the swcg? I haven’t seen that anywhere in the forums. Could a cleaning be needed?
 
the very first thing, do you have a surge protector on your power panel? if not you need one ASAP.. Amazon.com: Intermatic PS3000 Pool and Spa Surge Protective Device: Home Improvement

Brown outs, flickers and lighting kill VS pumps and just about any electrical equipment... I have 3, 1 on my pump panel, 1 on the whole house and 1 on the air conditioner.. then I have one on every outlet inside the house..

The SWG works on flow so your filter may be a little clogged and you need a higher rpm to get the same flow you had before... the cell may need to be cleaned but really running a lower CSI is the way to go as it will naturally clean the cell everyday.. muriatic acid take chlorine life of your cell every time you do it.. I went 7 years and never cleaned mine... :)

Thanks, the dirty filter theory makes sense, we opened super early (April 3rd) this year so dealt with a lot of pollen and other things dropping into the pool. I’ll find some time to clean everything up and see if that resolves anything.

Unless there is a surge protector built into my panel I don’t see anything. Any idea if these things have surge protectors in there?

nope, need to add it... install it in the very first slot so the spike hits it first.. On that, you will also need a 20 amp 240v breaker to install it into, needs to be it own breaker.. open the panel and look at the type of breakers you have and buy the same type 20 amp 240v breaker...

move this one down 1 slot and install the surge breaker in its slot..

on the bottom of the panel should be a 1/2 fitting to install it into...

I also installed this one in my main panel :)

I love this one and would have bought it if they had it 4 years ago...

Thanks for the help! I’ll get some added to the panel. Will probably have someone put a whole house unit in while I’m at it.
 
best thing I have done, have not had 1 issue since I have done mine :)
Cleaned the filter today and I am back down to 1400 rpms and the salt cell is detecting flow. Also had my electrician by on Saturday. He won’t touch the pool equipment but he’s putting a quote together to get me a new 100amp sub-panel with a whole house surge protector. I need the extra panel for some additional load I will be adding soon (EV Charger + a likely garage addition). Thanks again.
