Scalemaster Intermittent Bypass or Channeling in Resin Bed

Softener appears to regenerate but outlet water is intermittently hard

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Resin bed channeling due to incorrect flow rates, Partially open bypass valve, Resin loss from tank, Incorrectly sized Scalemaster unit for demand

Safety first: No special hazards, but avoid opening pressurised tanks.

Step-by-step checks:

1. Confirm bypass fully closed: Ensure the bypass handle is in the correct position.
2. Check usage vs capacity: Compare household water usage with the softener’s rated capacity. Oversized demand can cause breakthrough.
3. Run two consecutive regenerations: Manually trigger two full cycles to re-bed the resin.

If hardness remains intermittent, a technician should inspect the resin bed and distributors.
