TROUBLESHOOTING
Motor Will NOT Start – Check For:
1. Improper or loose wiring connections; open switches or relays; tripped circuit breakers, GFCI’s,
or blown fuses.
2. Manually check rotation of motor shaft for free movement and lack of obstruction. (See steps 4 & 5
of “Shaft Seal Change Instructions” in this manual.)
3. If you have a timer, be certain it is working properly. Bypass it if necessary.
Motor Shuts OFF – Check For:
1. Undersized wiring; loose connections; etc.
2. Low voltage at motor or power drop (frequently caused by undersized wiring or extension cord use).
3. Mechanical binding and electrical overload.
NOTE:
Your Advantage Pump motor is equipped with an “automatic thermal overload protector.”
The motor will automatically 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, provided the power source is again up to proper levels. It will continue to
cut On/Off until the problem is corrected.
Be sure to correct cause of overheating.
Motor Hums, But Does NOT Start – Check For:
1. Centrifugal switch stuck in OPEN position.
2. Binding of motor shaft.
Pump Won’t Prime
1. Make sure pump/strainer housing is filled with water and the cover O-ring is clean, also be sure it is
properly seated in the cover O-ring groove. Make sure strainer cover is locked firmly in position and
lubricated with “Jack’s 327.”
2. Make sure all suction and discharge valves are fully open and not blocked, that pool water level is at
proper level, and that skimmer wire is not hung up or binded on skimmer wall.
3. Block off to determine if pump will develop a vacuum. You should have 5”-6” of vacuum at the
strainer cover
(Only your pool dealer can confirm this with a vacuum gauge)
. You may be able to
check by removing the skimmer basket and holding your hand over the bottom port with skimmer
full and pump running. If no suction is felt, check for line blockage.
a. If pump develops a vacuum, check for blocked suction line or dirty strainer basket,
an air leak in the suction piping may be the cause.
b. If pump does not develop a vacuum and pump has sufficient “priming water”:
i. Re-check strainer housing cover and all threaded connections for suction leaks.
Check if all hose clamps are tight.
ii. Check voltage to ensure that the motor is rotating at full RPM’s.
iii. Open housing cover and check for clogging or obstruction in suction.
Check impeller for debris.
iv. Remove and replace shaft seal only if it is leaking.
