How do I know if my pool chlorinator cell is failing?
Most salt chlorinator cells last 3 to 7 years. The single earliest sign of a failing cell is your chlorine reading dropping despite the salt level and power supply looking fine.
The 5 warning signs
- Chlorine reading drops even though the unit says everything is fine
- Cell voltage or amperage warnings on the control box
- Visible scale, discolouration or worn plates when you pull the cell out
- Salt reading keeps climbing but chlorine isn't produced
- Cell trips the RCD or the control unit
When to acid-wash vs replace
Under 3 years with white crust — acid wash first. Over 5 years with low output and no scale — replace. 3–5 years — acid wash and retest. Method: 10 parts water to 1 part hydrochloric acid, submerge 15–30 minutes, rinse. Always acid into water.
Cost of replacement on the Gold Coast
Replacement cells: $400–$900 for a standard residential unit. Compared to $1,500–$3,000 for a new chlorinator system. We provide a written repair quote before any work begins.
