9. POOL PUMP TROUBLESHOOTING 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 (often 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 automatically shut off if the 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 from 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 until it moves freely. You may have to remove the protective metal cap from some models
to access the motor shaft.
NOTE
– All FlowXtreme, FX VS PRO II & FX PRO II pumps are run tested with water before leaving the
factory.
Water Leaks Around Intake and Discharge Fittings
– Check For:
1. Loose union fittings or hose fittings.
Solution:
Tighten fittings or remove, apply Teflon tape and reinstall.
2. Loose hose clamps on flexible hose.
Solution:
Tighten hose clamps using a nut driver or wrench instead of a screwdriver
3. Leaks that continue after trying the above solutions.
Solution:
Inspect union fittings and hose fittings for excess plastic mold flashing that can cause hoses
and plumbing not to seal. If plastic mold flashing is found, remove it with a fine tooth file or knife
blade and re-assemble. If the fitting still will not seal replace them and reassemble plumbing with new
fittings.
