TROUBLESHOOTING
A. Motor won’t start
1. Check for improper or loose connections, open switches, relays, blown circuit breakers or fuses.
2. Manually check rotation of motor shaft for free movement and lack of obstruction
B. Motor cuts out – Check for
1. Wiring, loose connections etc.
2. Low voltage at motor ( undersized wiring or improper incoming voltage )
3. Binding and overload.
NOTE: The pump motor is equipped with an automatic thermal overload protection. The motor will automatically shut-off
before heat damage due to an improper operating condition can occur. The motor will start automatically when safe heat level is
reached.
C. Motor hums but does not start
Check the capacitor
D. Pump won’t prime
1. Make sure strainer is filled with water and cover gasket is clean and in place.
2. Make sure that there are no leaks into the suction through loose bolts, connections, o-rings etc.
3. The suction and discharge valves must be open.
4. Block off suction as close to the pump as possible and determine if pump will develop a vacuum.
If vacuum does not develop
Tighten all bolts and fittings on suction side
Check voltage to make sure pump is up to speed
Open pump and check for clogging or obstruction.
Get the shaft seal replaced.
If vacuum develops, check for blocked suction line or strainer, or air leak in suction piping.
E. Low Flow
1. Clogged or restricted strainer or suction line; undersized pool piping.
2. Plugged or restricted discharge line of filter.
3. Air leak in suction ( bubbles issuing from return fitting )
4. Pump operating under speed.
5. Plugged or restricted impeller.
F. Noisy Pump
1. Air leak in suction causing rumbling in pump.
2. Cavitation due to restricted or undersized suction line and unrestricted discharge lines. Correct suction condition if
practical.
3. Vibration due to improper mounting.
4. Foreign matter in pump housing.
5. Bad motor bearings.
NOTE: Only qualified, licensed personnel should install the pump and connect the wiring. Consult your local authorized dealer or
service center if the suggestions in the troubleshooting section do not solve a problem you encounter.
