SPA TROUBLESHOOTING
If your spa doesn’t seem to be working the way you believe it should, please review the “START-UP” and “OPERATION” instructions in this manual. If this doesn’t help
you correct the problem, follow the appropriate instructions below. If the problem still is not resolved, call your Authorized dealer.
Priming the pump(s): Upon filling or refilling the spa, if a pump is operating and water is not flowing from any of its 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 (see page 24).
• Loosen the union on the top of the pump(s) to allow the air to escape(see page 25). 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.
