Trouble Shooting

Low / No Water Flow

  1. Make sure 3 fitting caps have been removed from inside spa suction & return flow fittings. These are only used when cleaning filter, to keep water from overflowing filter tank when lid is removed.
  2. Bleed air from filter tank. To do this make sure Power Pack is Unplugged from outlet. Open air valve on top of filter tank until water spews from valve. Close air valve, plug GFCI back into outlet. Verify there is good water flow by placing hand in front of lower water return inlet and feeling good water flow.
  3. Clean or replace filter cartridge. As the filter begins to get dirty, the flow of water slows down as the pump has a difficult time drawing the water through the dirt impregnated filter. This is the most common cause of a spa not heating. The spa can not heat without good water flow. See filter cleaning section.
  4. Pump impeller clogged with debris. With Power Pack unplugged, place caps over fittings in tub. Remove filter and drain filter tank. Look down in the center hole on the bottom of the filter tank and you will see the paddle wheel impeller from the pump. This is a magnetic drive circulating pump and it does not take much of a debris clog to keep it from spinning. Take a long, thin screw driver and place in the hole and try to turn it a few times. Remove screw driver and plug power pack in for a few seconds. If it spins freely on it's own, it should now pump water. Unplug unit, bleed air, plug back into wall receptacle and verify water flow with hand.
