To exit demo mode on the Fisher™ Spa or Vortex™ Spa, you can follow these steps on any SV Series controller, including Mini controls:
1. Ensure that the spa is completely empty of water and that the heater tube is also empty of water. This will cause the spa to display the ER3 - Water Prime error code.
2. While the error code is scrolling on the display, press the PUMP A button.
3. Immediately after pressing the PUMP A button, press the LIGHT ON button.
4. These two button presses should be done in quick succession.
