So this might be a dumb question but I'm having a hard time understanding what's happening(happened). Last week the pressure in my filter tank was high enough that the flow light on the SWG came on. This is the same point and pressure I normally need to back flush so nothing seemed out of the ordinary. I back flushed the filter but within 12 hours the pressure was back up and the no flow light came on again. At that point I decided to clean out the filter and give the screens an acid bath which I did. Once everything was back together, it worked initially but the pressure rapidly rose again and the no flow light came on within 16 hours. Also at this point the led screen on the SWG was flipping from low salt to low temperature to low flow which I had never seen before. My last step was to remove the salt cell and clean it out using an acid bath. There was not much on the way of scaling I could see but I did it anyway. Once I had everything back together, the pressure stayed down and the SWG is performing perfectly. We're now 3+ days after this process and things are working great.
My question is how can these two items possible be related? I just want to have an understanding for the next time this happens so my fix can be more targeted. Any help is much appreciated.
