Pool troubleshooting: How to change and maintain an AKERON pH/salt probe.

Client:
Hello,

Technical Advisor:
Hello

Client:
I have a saltwater filtered pool. A PH / salt regulator of the brand AKERON. When I press the boost button, the device goes into non-production mode and the message "defective or poorly connected electrode" is displayed. What should I do?

Technical Advisor:
If your probe is connected, then you need to replace it.

Client:
Okay, thank you. Is it difficult to do? Do I need a pool specialist?

Technical Advisor:
No, it's easy. Do you have the user manual for your device? You will need the pH probe: https://ph-redox-pool.com/gb/corelec/198-pH-Probe-for-Duo-sel-Regul-pH-Akeron.html
And the calibration solution indicated in your manual.

Client:
However, in normal mode it shows production at 60%. Is the pool really disinfected? There are algae deposits at the bottom of the pool.

Technical Advisor:
The pH is no longer regulated
And therefore you have algae.

Client:
The pH is displayed as 7.33.

Technical Advisor:

Client:
I will do that. Just for your information, this is the third summer that I have been using the probe for filtering, and in winter I do active wintering without removing the probe.
Is this the lifespan of a probe?

Technical Advisor:
2/3 years.

Client:
I conclude that the probe must be tired.
