My RA was bought in October, and I just put the ph probe online in late September.. It started off out of the box being sluggish and now it won't give anything more than zero on the calibration screen. Nothing has changed in my code or hardware. I think its an issue with the probe. I tried cleaning it in vinegar with no luck. Can you give me any advice?

Thanks!

Maybe there is more to this story... The ph seemed to jump up when ato was active earlier. It made it to about 5 then flatlined shortly after ato.

Float leak. You need a new float.

Is there a better float to purchase? This one is pretty new. Is the ph probe fried? Is there a better one? Just so i understand, are you saying I'm getting voltage in the tank from a float switch when ato is idle?

Thanks!

Let's try this:
Get a cup and fill it with tank water then place the ph probe inside of it.
What kind of readings do you get?

That didn't make a difference. Still shows ph of 1.28 (zero on calibration screen)
