Mechanical Troubles
and Noise.
Possible Cause
Pump overcurrent.
Pump may be running too slowly.
Pump may be too hot.
The pump motor is running but with loud noise.
Cavitation.
Corrective Action
Check trap basket; if plugged, turn
pump off and clean basket. Suc-
tion/discharge piping is too small.
Check and clean pool Ä lter.
Check voltage at motor terminals
and at meter while pump is run-
ning. If low, see wiring instructions
or consult power company.
Check for loose connections.
Check line voltage; if less than
90% or more than 110% of rated
voltage consult a licensed electri-
cian.
Increase ventilation.
Reduce ambient temperature.
Tighten any loose wiring connec-
tions.
Motor internal terminal overload
protector is open.
Motor runs too hot. Turn power to
motor off.
Check for proper voltage.
Check for proper impeller or impel-
ler rubbing.
If suction and discharge piping are
not adequately supported, pump
assembly will be strained. Do not
mount pump on a wooden plat-
form! Securely mount on concrete
platform for quietest performance.
Foreign matter (gravel, metal, etc.)
in pump impeller. Disassemble
pump, clean impeller, follow pump
service instructions for reassembly.
Improve suction conditions. In-
crease pipe size. Decrease number
of Ä ttings. Increase discharge
pressure.
