After filling or refilling the spa:

water is not flowing from any
of its jets.
• Pump is not properly primed. • Turn off power to the spa at the breaker and remove the
equipment compartment door (see the "Draining Your Spa"
section for illustration).
• Loosen the union on the top of the pump(s) (see the
"Winterizing Your Spa" section for illustration) to allow the
air to escape, and then hand-tighten the union(s).
• Turn power back on, activate the pump, and check to
make sure the union is tight enough to keep it from
leaking. Replace the equipment doors.
OR: Remove and reinstall the
FROG cap.
