SYMPTOM PROBABLE CAUSE SOLUTIONS
Upon filling or refilling the spa, if the pump is operating and water is not flowing from any of the
jets, the pump may not be properly primed. To correct, perform the following procedures:
• Turn off power to the spa at the breaker and remove the equipment compartment door.
• Loosen the union on the top of the pump to allow the air to escape. When water is present,
hand-tighten the union.
• Turn power back on, activate the pump and check to make sure union is tight enough to keep it
from leaking. Re-install equipment door.
