Hi everyone. Last season I installed a new Aqua pure SWG 1400 in my pool (full setup in signature below). Recently I have been having an intermittent problem that continues to become more frequent/permanent. This system has been working great for about 1-1.5 years with truly no issues until the last month or so.
I have been getting a no flow error. My first thought was its time to clean the unit so I did the muriatic acid wash on it. The was some scaling, nothing significant, but looked brand new after clean. I also cleaned the sensor with a light scrub pad per instructions online. Things were ok for a week after this.
I then thought maybe the unit is getting old (although less than 1.5 years old) and my 1500 RPM normal setting on my variable flow pump was too low. So I bumped it to 1750RPM and things were good.
Fast forward to today (2 weeks later) i am getting the same error. Even at high/max flow rates from pump.
When the unit starts and does it initial boot up things are fine and looks good - I get a flow signal and its producing chlorine. But within 5 minutes or so after it goes to no flow.
Thoughts on trouble shooting? I haven't contact Jandy yet as they customer service in the past has been less than helpful - aka they say call a pool "professional"
I am getting no other errors other than no flow also. Thanks!
