Display shows ICE or FR and pumps run automatically even when spa is not in use.

Note: ICE mode is a protective feature, not a malfunction.

• Verify conditions: Confirm outdoor temperature is near or below freezing. The spa is running pumps to prevent plumbing from freezing.
• Keep cover on: Ensure the Jacuzzi cover is closed and latched to retain heat.
• Check water level: Maintain proper water level so pumps do not draw air during freeze cycles.
• Do not shut off power: In freezing conditions, keep power on so freeze protection can operate.

If ICE displays in warm weather, the temperature sensor may be faulty and should be tested and replaced.
