Section 6. Troubleshooting and Repair

Zodiac strongly recommends that you call a qualified service technician to perform any repairs on the filter/pump
®
system. To locate a qualified technician, check your local yellow pages or visit www.zodiacpoolsystems.com or www.
zodiacpoolsystems.ca and click on "Dealer Locator."
Symptom
The cleaning/circulating
system is not operating
correctly.
Bubbles are present in the
pump basket.
Air leaks are still present.
There is no air in the
system, but the pressure is
still low.
There is no debris blocking
the impeller and the
pressure is still low.
The pump is leaking water
between the motor and
pump body.
Jandy Pro Series VS FloPro™ Series Variable-Speed Pump

Verify that skimmer baskets, pump basket and other screens are clean. Clean as
necessary.
Check filter and clean as necessary.
Check valve positions. Adjust as necessary.
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.
Check the cleaning system manual to ensure that the system is adjusted according to
the manufacturer's recommendations.
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 do a visual inspection of the lid seal looking
for cracks or gaps on the rubber surface. If none are observed, use a clean rag to
wipe the surface clean (note: the rag may show black material that came off the lid
seal). Use the rag again to clean the mating surface of the housing. Using a very
small amount of silicone lubricant (no Vaseline) will help make a proper seal and
protect the lid seal. 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. If problem is not
resolved lid seal replacement may be necessary.
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.
Reposition the pump next to the piping and secure the union nuts to the pump. With
clean union o-rings, hand-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.
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. See Section 6.1, Service
Technician Maintenance and Blocked Impeller, in this manual for more information.
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.
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.
Pump seal is leaking air. Have a qualified service technician replace the seal.
This is caused by a damaged or failed mechanical seal. Replace the seal.
