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.
