6.1 Troubleshooting
Symptom
Possible Cause/Solution
The cleaning/circulating
system is not operating
correctly.
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.
Bubbles are present in the
pump basket.
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.
Air leaks are still present.
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
.
There is no air in the
system, but the pressure is
still low.
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,
in this manual for more information.
There is no debris blocking
the impeller
and
the
pressure is still low.
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.
The pump is leaking water
between the motor and
pump body.
This is caused by a damaged or failed mechanical seal. Replace the seal. See
Section 6.2, Service Technician Maintenance, 6.2.3, Mechanical Seal Replacement,
in this manual.
The pump gets hot and
shuts off periodically.
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.
