PureLine SWG

[Marines75]

Hi Everyone,

I have a PureLine 40k gallon SWG. However the output of the chlorine display only goes up 30p when I turn it all the way to the right and no where near 100. It turns down to 0 when I turn it all the way to the left. Is there something I can do to fix it? Thanks so much!!

Sound like to me that either the knob is slipping or you have a bad potentiometer. First thing to try is to pull of the plastic black and yellow knob and see if you can get to 100% on the display by turning the shaft clockwise all the way.

Thanks so much. I tried to turn the shaft and still nothing. The number is jumping around now at 50p when all the way to the right.

What is the age of the unit? Have you called Inyopools?

It's 3 yrs old. I have not. That's a great idea, I didn't know I could give them a call.

Ugh, I left the door to my SWG controller box open this rainy weekend. Now I can't adjust my chlorine output by more than 10-15%. When the knob is all the way counter clockwise the display reads 39-40%. When its rotated ll the way clockwise the display reads about 50%. Looks like moisture has damage the output adjustment potentiometer. I made some voltage measurements on the potentiometer wiper output and it is stuck in a small range roughly between 2.5 to 2.8 volts over its complete rotation. So I order a new display board from InyoPools. Once I get the new board installed and working, I may try to replace the potentiomerter on the damaged board.

Received my replacement display board yesterday and installed it. Now all is good. Next step is to see if I can repair the original board.

@Marines75 , did you resolve your issue?

I was able to repair the damage board by replacing the output level adjustment potentiometer. I used this 10K potentiometer. It's identical to the one that it replaced.
