Troubleshooting
Problem
Possible Cause
Solution
The ‘Ionizing’
light is flashing red
The cell is not plugged in all the way
Make sure the cell cable is completely
plugged into the controller
The electrodes are not under water
Make sure the electrode bars are
completely under water. An air pocket can
form when the pump is not running, and
the tee is installed upside down.
The cell is worn down past its useful life
Change the mineral cell
There is scale on the electrodes
File the scale off the electrodes with a metal
file
I cannot get my copper level to reach
0.2ppm
You have not used the Large Dose function
Set the controller to Large Dose and set the
number to 99. After 99 hours (about 4
days), test again. If your copper level is
below 0.2ppm, do another 99-hour Large
Dose. Repeat until 0.2ppm copper is
reached
The Ion/Action setting is too low
If you find that the copper level reaches
0.2ppm but then drops off, set your
Ion/Action setting higher to compensate
There is not enough chlorine in the water
The chlorine or bromine should be
maintained at 1-3ppm until the copper level
reaches 0.2ppm. Once the copper level
reaches 0.2ppm, you can reduce the
chlorine/bromine concentration to 0.6-
1ppm
The mineral cell needs to be changed
Check the electrode bars on the mineral
cell. If they are 0.5” (10mm) or shorter, it is
time to change the cell
The phosphate level in the water is too high
Have your water tested for phosphates at a
pool store. If the phosphate level is above
200ppb, use products recommended at the
store to bring it down. If you live in a rural
area, you may need to reduce the
phosphate level on a regular basis
The test kit is expired
Check the expiry date on the test kit and
purchase a new one if it is expired
The test kit instructions are not being
followed
Be sure to read the test kit instructions and
follow them exactly
There is no power to the controller
The power outlet is dead
Check the power to the outlet by plugging
in another appliance
The controller is dead
Test the controller in another outlet that
you know works. If there is still no power,
see Warranty section below
The controller display shows
‘PL’ and I can’t
change the settings
The controller is set to Program Lock
Press and hold the + and
–
buttons
simultaneously for 20 seconds or until the
PL changes back to a number
There are two decimal places showing on
the display between the numbers
The Total Dissolved Solids (TDS) of the
water is low
Increase the TDS to the range
recommended above
The cell is almost worn out
Change the mineral cell
