Display shows EC or ECON, spa heats only during filter cycles and may not maintain set temperature.

Safety first: No internal electrical work is needed.

• Change heating mode: Use the mode button or settings menu on the topside panel to switch from Economy (EC) to Standard (ST) or Ready mode, following the Artisan Spas manual.
• Verify filter cycles: Ensure filter cycles are set appropriately so the spa has enough run time to heat if you choose to remain in economy mode.

After changing to Standard mode, allow several hours for the spa to reach and maintain the set temperature.
