Steps
Verify actual free chlorine in the water with a manual test kit — don't rely solely on the controller's displayed output percentage, which reflects cell operation, not confirmed sanitizer level.
Check salt level against the specific cell manufacturer's target range (ranges vary by brand/model), since under- or over-salting reduces or halts production.
Check water temperature; most salt cells sharply reduce or stop output below the manufacturer's minimum rated temperature (commonly a cutoff around 50–60°F depending on model).
Inspect the cell plates for calcium/scale buildup and acid-wash per the manufacturer's specific dilution and procedure if scaling is visible.
Confirm the polarity-reversal self-cleaning cycle is functioning and check the cell's rated amperage/cell-hours indicator against actual readings on the control board.
Known gotchas
Low displayed output can also mean the pool's actual chlorine demand exceeds the cell's rated capacity (e.g., undersized cell for pool volume/bather load) rather than a hardware fault — verify sizing before replacing parts.
High CYA or high pH reduces effective sanitizing chlorine even when the cell is producing at rated output, which can look like a 'cell problem' that is actually a chemistry problem.
Acid-washing a cell requires diluted acid, proper PPE, and the manufacturer's exact procedure — using the wrong concentration or dwell time can strip or damage the cell's coating.
