Whirlpool Regeneration Inhibition or Control Failure

Softener never regenerates (no cycles at all, even over weeks)

Possible Causes

Regeneration disabled in programming, Flow meter not registering, Faulty control board, No power to unit

How to Fix / Troubleshooting

Safety first: Ensure the unit is plugged into a properly grounded outlet. No plumbing work is required for initial checks.

Steps to check:

  • 1. Confirm power: Verify the display is on. If not, check the outlet and transformer.
  • 2. Check programming: Ensure regeneration is enabled and not set to "off" or vacation mode.
  • 3. Test manual regeneration: Attempt to start a manual regeneration from the control panel. If it will not start, the control board or keypad may be faulty.
  • 4. Verify flow meter: Run water and confirm the unit registers usage. If not, troubleshoot the turbine sensor.

When to call a technician: If the unit has power but will not regenerate manually or automatically, the control board likely needs replacement.
