Section 6. Troubleshooting and Repair
Jandy
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.jandy.com and

6.1
Troubleshooting
Symptom
The cleaning/circulating system is
not operating correctly.
Bubbles 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.
The pump gets hot and shuts off
periodically.
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 cleaning system from working properly.
Check the cleaning system manual to ensure that the system is adjusted according to the
manufacturer's recommendations.
Air in system. Check the pool or spa water level to ensure it is at the proper level and that air
is not being drawn into the suction piping. If the water is at normal level, turn off the pump.
Remove the lid and check for debris around the lid o-ring seat, as this will cause air leaks
into the system. Clean the lid o-ring and place on the lid. Hand-tighten the lid to make an air
tight seal. Do not use any tools to tighten the lid. Turn the pump back on.
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 6.2, Service
Technician Maintenance, 6.2.1 "Blocked Impeller" 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. See Section 6.2,
Service Technician Maintenance, 6.2.4 "Mechanical Seal Replacement".
Ensure 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.
