Troubleshooting
Description Art.No
Improper or loose wiring connections; open switches or
relays; tripped circuit breakers, GFCI's, or blown fuses.
MOTOR WILL NOT
Manually check rotation of motor shaft for free move-
START
ment and lack of obstruction.
If you have a timer, be certain it is working properly.
Bypass it if necessary.
Undersized wiring; loose connections; etc.
Low voltage at motor or power drop (frequently caused
MOTOR SHUTS OFF
by undersized wiring or extension cord use).
Mechanical binding and electrical overload.
Centrifugal switch stuck in OPEN position.
MOTOR HUMS BUT
DOES NOT START
Binding of motor shaft.
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".
Make sure all suction and discharge valves are fully
open and not blocked, that pool water level is at proper
level, and that skimmer weir is not hung up or stuck on
skimmer wall.
Block off to determine if 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 port
PUMP WON'T PRIME
with skimmer full and pump running. If no suction is felt,
check for line blockage.
a. If pump develops a vacuum, check for blocked suc-
tion line or dirty strainer basket, and air leak in the suc-
tion 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 clogging or obstruction in
suction. Check impeller for debris. IV. Remove and
replace shaft seal only if it is leaking.
