Chlorinator not making enough chlorine? We test the water, the cell, and the flow so you don't buy parts you don't need.
What we do
Chlorinator cell and controller fault finding
Before we arrive
Send a photo of the screen while the pump is running, and your latest water test.
Safety first
Turn off the chlorinator if it smells burnt or the power cord is damaged.
The screen says low salt or low flow
The pool is green but the unit is on
The cell is covered in white scale
The screen is blank or keeps resetting
The chlorine levels are always low
You need to know if the cell is dead
Real salt and chlorine levels in the water
Water flow through the cell
Cell plates and scale build-up
Output settings and timers
Power connections to the cell
Age and size of the chlorinator
Pool equipment we work on
We check the equipment, water path and controls before we recommend a repair.
Common problems
The same problem can have a few different causes. We test before we start replacing gear.
What might cause it
The pool may still be below range, or cold water, scale, cell wear or incorrect calibration may be reducing the conductivity reading
How we check
We test salinity independently, inspect the cell plates and compare the result with the controller's diagnostic value before adding more salt
What might cause it
High calcium saturation, elevated pH or alkalinity, poor cell cleaning, or a polarity-reversing fault
How we check
We test calcium hardness, pH and total alkalinity, inspect the cell and confirm that the controller is reversing polarity correctly
What might cause it
The cell may be near the end of its life, the run time may be too short, or algae and other contamination may be consuming chlorine as it is produced
How we check
We inspect the cell, verify the operating hours and test the pool's chlorine demand, stabiliser and circulation before condemning the unit
Our process
We check the real salt and chlorine levels first.
We make sure water is moving through the cell properly.
We inspect the cell and see if it is producing gas.
We clean the cell, fix the settings, or replace broken parts.
After the visit
We balance the water and set the right timers.
We clean the scale off or fit a new cell.
We fix the power fault or quote a new unit.
Questions
Straight answers to the questions we hear most often.
Not always. Cold water and dirty cells can make the reading wrong. Always test the water first.
High calcium or bad water balance causes scale. Cleaning it in acid too often will ruin the cell.
It just means the box is trying to work. The cell might still be dead.
Yes, if it is not making enough chlorine. But bad flow or low stabiliser can also cause it.
Only if both are broken or very old. We check what actually needs replacing.
