Pump runs but spa does not spill over or spa jets are weak when spa mode is selected.

Safety first: Turn off power before manually moving valve actuators.

• Check valve positions:
  • Verify suction and return Jandy valves are set correctly for spa mode (suction from spa, return to spa).
• Inspect actuators:
  • If using Jandy valve actuators, ensure they rotate fully and are not stuck mid-position.
  • Adjust actuator cam stops if valves are not aligning correctly.
• Bleed air:
  • Run pump in spa mode and open any air bleed valves to purge trapped air.
• If flow remains weak: Check for obstructions in spa jets or partially closed spa return valves; consult a technician if plumbing issues are suspected.
