Hello Forum, I have a prob with my SWG and wondered if anyone has had/seen this issue.
Just fyi, my water analysis report today ( from Leslies ):
Pump run time 10 Hr/Day
Pool size 14000 gal.
Location DFW Texas
No visible algae in pool
Problem: I had a Swimpure Plus installed around March 2012. It worked fine for 2 years when the main circuit board failed. It was repaired under warranty, and did work after this but I noticed I had to turn the generation % up quite a bit, compared to the original. That is, where I used to run it arount 50-60% in the summer, I now required 80-90%. This didn't bother me (maybe it should have) as I thought this was just a calibration issue, and as long as it worked I didn't care what the % setting was.
But this problem has dogged me over the last year; even at higher %, it can't seem to keep up the chlorine level. I remember in the winter having to turn it way down to keep the CL at 2-3 ppm. I have had the cell tested by Leslies, which tests OK on a few occasions. My SWG reports 27V, 5A across the cell- it should be generating Chlorine.
I contacted Hayward support again today and I was told that the readings (below) are normal and it all must be due to my phosphate level, which is high at 150 ppb. I don't find this too believable, but I am working on bringing my CYA and Phostphates in line.
My SWG Diags are:
60F water temp
27.6 cell voltage
5.27 cell current
100P run percentage
-3000 instantaneous salt level
R.159 SW version
T-15 Cell type
So, has anyone experienced this type of problem? In particular, with a new circuit board installed, a change in % setting required.
My software version on the board is 1.59 (I don't know what the original was). Anytime I mention the change in behavior (different % required as soon as new board installed) both Leslies and Hayward just gloss over it; explaining that the difference must be due to cold water temp, warm water temp, water chemistry etc. etc...
I am keen to get this resolved before it warms up too much here in Tx..
