I have a T-15 cell that is 9 years old and has been maintained as per the manufacturers guidelines. This year when it started to warm up I noticed it wasn't keeping the Cl2 levels where it normally did in past years. So I jacked up the output and it didn't seem to help. I figured it was time to replace it since it was 9 yrs old. So I bought a new T15 cell from Hayward and put it in.
I have it set on 35%, which is higher than was normally needed. Normally 20-25% would keep my Cl2 at the needed levels. However when I go to my Diagnostics on the Goldline, it will more often than not say zero volts and zero amps. Sometimes, it will be around 26 volts and 5-6 amps.
Is the setting of 35% a cell runtime percentage or an output %? I thought it just meant that it ran 100% of the time the pump was on but at 35% output.
I am guessing the board may be going bad? I soldered it about 4 yrs ago to fix the bad solder joint on it.
The pool is an 18k gallon, in ground vinyl pool. Thanks for any input!
