Rayne Under-Sized or Under-Programmed Softener

Rayne softener uses salt but water is still slightly hard at fixtures

Possible Causes

Hardness setting too low, Household water usage higher than design, Incorrect resin volume programmed, Bypass leakage mixing hard water

How to Fix / Troubleshooting

Safety first: No internal disassembly required.

1. Re-test hardness: Confirm actual hardness and compare to programmed value. Increase the setting if needed.
2. Check bypass valve: Ensure the Rayne bypass is fully in SERVICE and not partially open to BYPASS.
3. Adjust capacity: In the controller, verify the correct resin tank size and capacity are set. Reduce capacity slightly to force more frequent regenerations if needed.

When to call a technician: If the softener is undersized for your home, a Rayne dealer can recommend an upgrade or additional unit.
