Safety: No internal service required.

  • Change mode: On the QCA Spas topside panel, press the MODE or TEMP button sequence to switch from EC/ECO to ST (Standard) mode so the spa can heat whenever needed.
  • Verify filtration schedule: Ensure the spa is not limited to heating only during short filter cycles if you want faster recovery.
