- 1). Check that the pump pot is full of water if the pump will not prime. The pump requires a flow of water through it to prime correctly. Ensure that the O-ring, or seal, on the lid to the pump pot is secure and free of damage. Replace the seal if it is hard and flat.
- 2). Check for sand caught between the rotor-like impeller and the pump body, if the pump hums then switches off with a clicking sound. Switch off power to the pump and try and turn the motor shaft by hand. If this does not work, check the impeller for obstructions. Remove the basket and inspect the impeller by placing a finger into the suction hole situated on the pump strainer housing. Replace any broken seals.
- 3). Inspect the household electrical panel to see if any breakers have tripped if the pump will not run at all. Reset breakers and look for blown fuses. Replace fuses as needed. If there is a timer on the system, check to see that it is working correctly.
- 4). Place a piece of rubber or carpet between the pump and its base if the unit is excessively noisy. The bearings may be worn. Have a qualified Aquastar technician investigate further and replace the bearings, if necessary.
- 5). Raise the water level if you notice bubbles coming into the pool. If the pool water level becomes too low, air could mix with water through the skimmer. Verify that the skimmer weir, or "flapper," is not stuck in the up position. This can allow air into the system.
- 6). Verify that the pump motor is wired to the correct voltage if the unit cuts off every few seconds. The correct voltage should be either 115v or 230v. If the pump continuously shuts down, turn off the power and have an electrician investigate further.
