TROUBLE SHOOTING

MOTOR WILL NOT START

• Improper or loose wiring connections; open switches or relays; tripped circuit breakers,

GFCI’s, or blown fuses.

• Manually check rotation of motor shaft for free movement and lack of obstruction.

• If you have a timer, make sure it is working properly. Bypass it if necessa.

MOTOR SHUTS OFF

MOTOR HUMS BUT DOES NOT START

• Undersized wiring; loose connections; etc.

• Low voltage at motor or power drop (frequently caused by undersized wiring or extension cord use).

• Mechanical binding and electrical overload.

• Centrifugal switch stuck in the OPEN position.

• Binding of the motor shaft.

PUMP WON’T PRIME

•Make sure pump strainer housing is lled with water and the cover O-ring is clean; also, be sure it is

properly seated in the cover O-ring groove. Make sure the strainer cover is locked rmly in position

and lubricated with “Jack’s 327”.

• Make sure all suction and discharge valves are fully open and not blocked, that the pool water level

is at a proper level and that the skimmer weir is not hung up or stuck on the skimmer wall.

• Block o to determine if the pump will develop a vacuum. You should have 5”-6” of vacuum at the

strainer cover. You may be able to check by removing the skimmer basket and holding your hand over

the bottom po with the skimmer full and pump running. If no suction is felt, check for line blockage.

• a. If pump develops a vacuum, check for a blocked suction line or diy strainer basket, and an air

leak in the suction piping may be the cause.

• b. If the pump does not develop a vacuum and the pump has sucient “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. iii. Open housing cover and

check clogging or obstruction in suction. Check impeller for debris. iv. Remove and replace shaft seal

only if it is leaking.

PRIMING

Fill strainer housing with water to suction pipe level. If water leakage occurs anywhere on the pump or

lter, DO NOT sta the pump. If no leakage occurs, stand at least 10 feet from the pump and/or lter

and proceed with staing the pump.
