1. Check the suction side piping union. While the pump is running, try to tighten the union. If this does not stop the air leak, turn off the pump. Loosen both unions and slide the pump out of the way. Remove, clean, and re-install both union o-rings.
2. Reposition the pump next to the piping and secure the union nuts to the pump. With clean union o-rings, and-tightening of the unions should create a seal. If the unions still do not seal, gently tighten with a large pair of tongue-and-groove pliers. Do not over-tighten.

Air is in the system. Check the pool or spa water level to ensure that it is at the proper level and air is not being drawn into the suction piping. If the water is at the normal level, turn off the pump. Turn the lid's locking ring counter-clockwise until 'START' aligns with the ports. Remove the lid and check for debris around the lid seal seat OR improper installation of the lid seal, as either condition will allow air to leak into the system. Clean the lid seal and replace it on the lid. Replace the lid on the pump housing. Align 'START' with the ports and turn the locking ring clockwise until 'LOCKED' aligns with the ports. Hand-tighten the lid to make an air-tight seal. Do not use any tools to tighten the lid. Turn the pump back on.

1. Improper low-voltage wiring. Check low-voltage wiring between pump and controller. Correct if necessary. See “3.2 Electrical Installation” in the Owner's Manual
2. Improper pump address set. Ensure pump dip switches 3 and 4 are set properly for the installation. Both should be OFF for use with Variable-Speed Controller or set to the proper address when connected to an AquaLink RS, AquaLink PDA, or an AquaLink Z4. See “3.2.4.1 Install with AquaLink® controller” in the Owner's Manual

Fault condition exists. View fault message on controller and correct fault before proceeding. If unsure how to correct fault, contact Zodiac Technical Support at 800.822.7933.

1. No power to pump. Make sure pump is properly connected to high voltage. See “3.2 Electrical Installation” in the Owner's Manual
2. Improper low-voltage wiring. Check low-voltage wiring between pump and controller. Correct if necessary. See “3.2 Electrical Installation in the Owner's Manual”
3. Improper pump address setting. Make sure that pump dip switches 3 and 4 are set properly for the installation. Both should be OFF for use with Variable-Speed Controller or set to the proper address when connected to an AquaLink® RS controller, an AquaLink PDA, or an AquaLink Z4. See “3.2.4.1 Install with AquaLink® controller” in the Owner's Manual
4. Fault condition exists. View fault message on controller and correct fault before proceeding. If unsure how to correct fault, contact Zodiac® Technical Support at 800.822.7933.

1. Verify that skimmer baskets, pump basket and other screens are clean. Clean as necessary.
2. Check filter and clean as necessary. Check valve positions. Adjust as necessary.
3. NOTE Multiple pieces of equipment operating at one time (for example, waterfalls, spa jets, and surface returns) will affect the proper operation of the cleaning system.
4. Check the cleaning system manual to ensure that the system is adjusted according to the manufacturer's recommendations.

Make sure that there is adequate room around the motor to circulate air and keep the motor cool. Have a qualified electrician check for loose connections and check the voltage at the pump motor while it is in operation. The voltage must be within 10% of the motor's data plate rating. If the voltage is not within 10%, contact a qualified electrician and/or the local power service provider.

This is caused by a damaged or failed mechanical seal. Replace the seal.

It is possible that debris is caught in the pump impeller. The pump impeller moves the water, and the vanes in the impeller can become blocked with debris.

1. The pump impeller and diffuser are showing signs of normal wear. Have a qualified service technician check the impeller and diffuser and replace as necessary.
2. If the pump is part of a relatively new installation, it could be an electrical problem. Contact a qualified service technician. Have the technician check for loose electrical connections and check the voltage at the pump motor while it is in operation. The voltage must be within 10% of the motor's data plate rating. If the voltage is not within 10%, contact a qualified electrician and/or the local power service provider.
3. Pump seal is leaking air. Have a qualified service technician replace the seal.

1. Incorrect dip switch setting. Make sure pump dip switches 1 and 2 are both ON if the controller is the JEP-R and both are OFF if the controller is a PDA, AquaLink RS, or AquaLink Z4. See “3.2.4.1 Install with AquaLink® controller” in the Owner's Manual
2. Improper low-voltage wiring. Check low-voltage wiring between pump and controller. Correct if necessary. See “3.2 Electrical Installation” in the Owner's Manual
