Display shows “Err 08” and no water is softened even though unit appears to run

Safety first: Ensure power is available and water is on; no internal high-voltage work is required for this check.

Step-by-step checks:

• 1. Verify settings:
  • Enter programming mode on the Kenmore control.
  • Confirm water hardness, salt type, and capacity are set according to your water test and manual.
• 2. Check bypass position:
  • Verify the Kenmore bypass valve is fully in the “Service” position, not in bypass or a mid-position.
• 3. Confirm flow meter operation:
  • Run a cold faucet and watch the display for flow indication (some models show a faucet icon or flow rate).
  • If no flow is detected, inspect and clean/replace the turbine / flow meter assembly.
• 4. Reset control:
  • Unplug the unit for 5 minutes, then plug back in and reprogram.
  • If Err 08 returns and flow meter is good, replace the electronic control board.
