Water remains hard at faucets even though the Lindsay softener appears to run normally (no error code)

Safety first: Shut off water and relieve pressure before opening any plumbing or tanks.

• Check bypass position: Confirm the Lindsay bypass is fully in Service position. A partially open bypass can mix hard and soft water.
• Test hardness: Use a hardness test kit at a faucet before and after the softener. If both are similar, the softener is not exchanging properly.
• Inspect salt and brine: Ensure adequate salt in the brine tank and that there is water at the bottom. Break up any salt bridge and remove salt mushing.
• Run manual regeneration: After correcting salt issues, run a full manual regeneration and retest hardness.
• Evaluate resin age: If the system is older than 10–15 years or has seen high iron, plan to replace the Lindsay resin with the correct volume and type.
