9. GENERAL POOL PUMP TROUBLE SHOOTING GUIDELINES:
MOTOR WILL NOT START – CHECK FOR
Make sure the terminal board connections agree with the wiring diagram on motor data plate label. Be sure
motor is wired for available field supply voltage (see pump operating label).
1. Improper or loose wiring connections; open switches or relays; tripped circuit breakers, GFCI's, or blown fuses.
Solution: Check all connections, circuit breakers, and fuses. Reset tripped breakers or replace blown fuses.
2. Manually check rotation of motor shaft for free movement and lack of obstruction.
3. If you have a timer, be certain it is working properly. Bypass it if necessary.
MOTOR SHUTS OFF – CHECK FOR
1. Low voltage at motor or power drop (frequently caused by undersized wiring or extension cord use).
Solution: Contact qualified professional to check that the wiring gauge is heavy enough.
2. Motor may be overheating due to direct sunlight or low water level in the pump basket.
Solution: Check water flow to insure uniform amount of water coming to the pump.
NOTE - Your pump motor is equipped with an "automatic thermal overload protector." The motor will automati-
cally shut off if power supply drops before heat damage can build up causing windings to burn out. The "thermal
overload protector" will allow the motor to automatically restart once the motor has cooled. It will continue to
shut off until the problem is corrected. Be sure to correct cause of overheating.
MOTOR HUMS, BUT DOES NOT START – CHECK FOR
1. Impeller jammed with debris.
Solution: Have a qualified repair professional open the pump and remove the debris.
2. Motor is frozen either form months in the carton after manufacturing or from over winter storage.
Solution: Insert a flat bladed screw driver into the slot at the back end of the motor shaft and turn motor shaft un-
til it moves freely. You may have to remove the protective metal cap from some models to access the motor shaft.
NOTE – All pumps are run tested with water before leaving the factory.
PUMP WON'T PRIME - CHECK FOR
1. Empty pump/strainer housing
Solution: Make sure pump/strainer housing is filled with water and cover o-ring is clean. Ensure o-ring is prop-

Solution
1. The pump will try to
restart automatically in 6
seconds after the phase
wire is well connected.
1. After communication
is restored, the pump will
restart automatically.
