6.1 troubleshooting
Symptom
Possible Problem/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) may prevent the cleaning system from working
properly.
Check the cleaning system manually to ensure that the system is adjusted
according to the manufacturer's recommendations.
Bubbles present in the pump
basket.
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 or
improper installation of the lid seal, as this either of these conditions will cause air to
leak 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.
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,
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, 6.2.4, Mechanical Seal Replacement
.
The pump gets hot and shuts
off periodically.
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.
