Display shows ICE or IC; pumps run automatically even when spa is not in use.

Safety: Do not disable freeze protection in cold climates; it prevents plumbing damage.

• Step 1 – Confirm conditions: If outdoor temperatures are near or below freezing, this is normal operation. Allow the spa to run.
• Step 2 – Check water level and cover: Maintain proper water level and keep the Vita Spa cover closed to help the system warm up.
• Step 3 – Sensor verification: If ICE appears in warm weather, test the ambient or water temperature sensor for incorrect readings and replace if faulty.
• Step 4 – Control pack: Persistent false freeze protection may indicate a control board issue; consult a technician.
