POSSIBLE CAUSES
a. Bad bearings.
These motors will run hot to the touch, however, this is normal. They are designed that
way. Thermal overload protector will function to turn them o if there is an overload or high
temperature problem. Excessive heat can be caused by:
a. Low voltage.
b. Installed in direct sun.
c. Poor ventilation.
a. Air leak in suction line.
b. Restricted suction line due
to blockage or under size pipe.
Indicated by high vacuum reading
at pump suction.
c. Foreign matter (gravel, metal,
etc.) in pump impeller.
d. Cavitation.
a. Motor is not connected properly.
b. Low voltage due to under size
wire or low incoming voltage.
c. Wrong size heaters in protective
device.
d. Overload due to binding in pump
or wrong size impeller.
a. Control Box.
b. Air tubing.
a. Control Box Components.
a. Debris in pump casing/impeller.
b. Improper swim jet assembly.
SOLUTION
Check for noise when shaft is turned by hand. Motor
will be very hot in bearing area when running. Replace
bearing.
Increase size of electrical wire. Be sure motor is
operating on correct voltage.
Shield motor from sun's rays.
DO NOT block motor ventilation openings.
Repair leak. Check suction pipe, red filler plug, and
o-ring (See Problem 1).
Remove blockage or increase suction pipe size. Are all
suction valves fully open?
Disassemble pump and remove foreign matter from
impeller.
Improve suction conditions. (Reduce suction line
length, reduce number of fittings, increase pipe size.)
Check wiring diagram on motor.
Check with volt meter. Increase size of supply wire.
Report low supply voltage to power company. Voltage
at motor must be within 10% of motor nameplate
voltage.
Heaters should be one size larger than full load amps
shown on motor nameplate.
Indicated by high amperage readings on motor, binding
shaft. Disassemble unit and correct.
Check GFCI. If green LED does not stay ON, contact a
certified electrician to diagnose control box compo-
nents.
Check air tubing connection on the control box. Check
that tubing is not bent or pinched. Tubing may need to
be replaced
Press TEST button on the control box GFCI to turn o
system. Contact a certified electrician to diagnose con-
trol box components.
Contact your local pool service company to check in-
side pump casing for any debris.
The internals may need to be removed for inspection.
