Display shows “Err 8” and the system appears to overfill or underfill the brine tank.

Safety: Disconnect power and close the inlet valve before removing the meter.

Steps:

• Locate the meter: On Clack WS-series valves, the turbine flow meter is typically mounted on the outlet side of the valve body.
• Inspect meter cable: Ensure the meter cable is firmly connected to both the meter and the control board. Look for cuts or abrasions in the cable. Replace the Clack meter cable if damaged.
• Check turbine for blockage: Remove the meter housing according to the service manual. Inspect the turbine for iron, sand, or debris that could prevent free spinning. Clean gently with water.
• Spin test: The turbine should spin freely with a gentle puff of air or water. If it binds or wobbles, replace the Clack turbine meter assembly.
• Verify programming: Confirm that the correct meter type and capacity are programmed in the controller. Incorrect settings can cause Err 8 and improper brine refill volumes.
• Board check: If a known-good meter and cable are installed and Err 8 persists, the control board’s flow sensing circuit may be defective and require replacement.

Tip: Install a prefilter upstream if debris repeatedly clogs the meter.
