Display shows EC or ECO; the spa heats less frequently and may not maintain high temperatures.

Note: EC is typically a mode indicator, not a fault, on many Lifesmart control systems.

• Check user manual: Refer to the Lifesmart spa manual for your specific model to understand the behavior of EC/Economy mode.
• Change mode: Use the topside control panel to switch from EC/Economy to Standard or Ready mode (often by pressing a combination like Temp + Light or the Mode button).
• Verify filter cycles: Ensure the programmed filter cycles are appropriate. In Economy mode, heating may only occur during filter cycles.
• Panel reset: If the panel is unresponsive, power cycle the spa at the GFCI breaker and re-enter the settings.
