FL / CLN Codes ExplainedUpdated a day ago

If your Viking Gen 2 Chiller displays FL or CLN codes, it indicates there is a flow issue or a component needs cleaning or replacement.

Common Causes:

• Dirty water filter (located on the back of the chiller)

• Dirty inline hose strainer

• Air trapped in the system

• Dislodged O-ring

Before Proceeding with Deeper Troubleshooting, Please Ensure:

• The water filter has been replaced recently

• The inline hose strainer has been cleaned

Troubleshooting Steps:

1. Check the Flow Meter

   • Clean the flow meter as needed 

2. Secure the Filter Canister

   • Make sure the filter canister is properly attached to the chiller.

   • Thread the canister slowly and gently to avoid cross-threading.

   • Use the provided wrench from the fitting bag to tighten securely.

3. Inspect the Inline Hose Strainer

   • Verify the strainer is positioned straight and screwed on tightly.

   • Check for any visible air bubbles in the strainer or hoses.

4. Check All O-Rings

   • Ensure white rubber O-rings are in place on all hoses and the inline hose strainer.

   • It’s common for the chiller-side inline hose strainer O-ring to become dislodged.

   • Replacement O-rings are provided; consult pages 22 and 23 of your manual for their correct placement.

5. Re-Orient the Hoses

   • Remove any twists, loops, kinks, or upward angles in the hoses between the tub and chiller.

   • Confirm that the 90-degree angled ends of the hoses are connected to the tub properly.

6. Release Trapped Air

   • Turn off the chiller.

   • Remove the flow meter to release any trapped air inside the system.

   • Reinstall the flow meter securely.
