Softener emits an unusual odour from the brine tank or softened water has a musty smell.

Safety first: Wear gloves and eye protection. Do not ingest water that smells unpleasant; use bypass for drinking water until resolved.

• Clean brine tank: Empty the brine tank of salt and brine. Scrub the interior with a mild bleach solution (per Kinetico guidelines), then rinse thoroughly.
• Disinfect resin bed: Follow Kinetico UK's recommended procedure for sanitising the resin using an approved disinfectant. Do not improvise with unapproved chemicals.
• Use fresh salt: Refill with new, sealed salt and ensure the lid is properly fitted to reduce contamination.
• Increase regeneration frequency: If the system sits idle for long periods, consider programming more frequent regenerations to keep brine fresh.

Warning: Always flush the system thoroughly after disinfection before using water for drinking or cooking.
