15. TROUBLESHOOTING

PROBLEM FOUND
Filtering medium clogged or
contaminated
Water balance problem. Check the
water's chemical parameters.
1- Low chlorine
Insufficient filtering time
level that cannot
be raised.
Lack of stabilising agent in the pool with
major exposure to UV and/or high use
Electrode-level problem
Saturated sensor
2- pH/ORP values
Presence of air bubbles at the vessel's
are extreme or
head
unstable
Defective sensor
Contaminated or outdated calibration
solution
3- Impossible to
calibrate the
Sensor clogged or covered in limescale
pH/ORP sensor
Defective sensor (damaged membrane...)
Certain sensors respond more slowly
than others do. In such cases, wait a few
hours until stabilisation occurs.
4- Slow sensor
response
Insufficient flow rate in the electrode
measurement chambers
CAUSE
30
POSSIBLE SOLUTION
Use a filter cleaner or replace the filtering medium.
pH [7.2 - 7.6] / combined chlorine (DPD3) < 0.6 ppm
/ stabilising agent [20 - 30 ppm] / TAC [80 - 120 ppm]
/ TH [180 - 250 ppm
Increase the filtering time (filtering time in h = water
temperature / 2)
3
Add 20 to 30 g/m of stabilising agent (cyanuric acid)
Check the electrode's connection, as well as the
production of chlorine gas bubbles in the vessel.
Immerse the sensor in a hydrochloric acid solution
diluted to 10% for 1 hour.
Flush out the measuring chambers while softly
unscrewing the sensor-holder and holding the
sensor in place.
Replace sensor
Replace the calibration solution
Clean the sensor in accordance with the procedure
indicated in the chapter on ORP & pH sensor
maintenance.
Replace sensor
Clean the sensor with clean water and drain the
excess by shaking slightly without rubbing.
If the problem continues, follow the instructions in
Make sure the water is flowing properly in the
electrode measurement chambers and that there
are no air bubbles (flush if necessary).
