PROBLEM
POSSIBLE CAUSES
SOLUTION
1. Pump will not prime.
a. Suction air leak.
b. No water in pump.
c. Closed valves or blocked lines.
d. Low voltage to motor.
Make sure the see-through lid and o-ring are clean
and properly positioned. Tighten see-through lid (hand
tight). Tighten all pipes and fittings on suction side of
the pump. Be sure water in the pool is high enough to
flow through skimmer.
Make sure strainer tank is full of water.
Open all valves in system. Clean skimmer and strainer
tank. Open pump and check for clogging of impeller.
Check voltage at motor. If low, pump will not come up
to speed.
2. Motor does not turn.
a. No power to motor.
b. Pump jammed.
Check that all power switches are on. Be sure fuse
or circuit breaker is properly set. Time set properly?
Check motor wiring at terminals.
With power off, turn shaft. It should spin freely. If not,
disassemble and repair.
3. Low flow.
a. Dirty filter.
b. No skimmer basket.
c. Closed valves or blocked lines.
d. Suction air leak.
Back wash filter when filter pressure is high, or clean
cartridges.
Clean skimmer and pump strainer basket.
See problem 1.
See problem 1.
4. Noisy operation of motor. a. Bad bearings.
Noise when shaft is turned up by hand. Motor is hot in
bearing area when running. Replace bearing.
5. Motor runs hot.
These motors will run hot to the touch, however, this is normal. They are designed that
way. Thermal overload protector will function to turn them off if there is an overload or high
temperature problem. Excessive heat can be cause by:
a. Low voltage.
b. Installed in direct sun.
c. Poor ventilation.
Increase size of electrical wire. Be sure motor is
operating on correct voltage.
Shield motor from sun’s rays.
Do not tighten cover or enclosure motor.
6. Noisy operation of pump. a. Air leak in suction line. Bubbles
in water returning to pool at inlet.
b. Restricted suction line due
to blockage or under size pipe.
Indicated by high vacuum reading
at pump suction.
c. Foreign matter (gravel, metal,
etc.) in pump impeller.
d. Cavitation.
Repair leak. Check suction pipe, see-through lid in
place? O-ring clean?
Remove blockage or increase suction pipe size. Make
sure strainer tank is clean. Are all suction valves fully
open?
Disassemble pump and remove foreign matter from
impeller.
Improve suction conditions. (Reduce suction life,
reduce number of fittings, increase pipe size.) Increase
discharge pressure and reduce flow by throttling
discharge valve.
