Hello

It is possible that your sensor is a problem, Try this test:

IS MY PH PROBE OUT OF SERVICE?
In order to check, if your pH probe works, you can:

1. Dip the probe in a glass of water

2. Read pH value

3. Add vinegar to water

4. Read the pH value again

If the pH value drops 1 or 2 pH units then your probe is most likely working.

Caution: If your probe is old. It may not hold up over time!

If it works try dipping your probe in pH 7, the value read should be close to 7

Then the probe it is very likely that the probe is out of service because it should react. Try again to turn off and restart your regulator, you never know
