TROUBLESHOOTING
Common Problems
Fail to start
•
No power
Check that all electrical switches are on. Ensure the circuit breakers are properly set. Check motor
wiring at terminals.
•
Pump shaft locking
Check that the pump can be rotated by hand and remove any blockage.
•
The pump shaft is damaged
Replace the motor or the bearing.
Pump Faulty
•
The pump does not start, leaks, or has too much air
Check the suction pipe and cap on any suction gate valve. Secure the cover to the pump filter tank
and ensure that the cover gasket is in place. Check the water level to ensure the skimmer is not taking
in air.
•
The pump does not start up, and there is not enough water
Ensure that the suction lines, pumps, filters, and pump strainer housing are filled with water. Make
sure that the valves in the suction line are working and open (some systems have no valves). Check
the water level to ensure that there is water through the skimmer.
•
Pump filter basket is blocked
Clean the pump body. Replace the filter basket.
Reduced capacity
•
Suction air leak
Check the suction lines and cap on any suction gate valve. Secure the cover to the pump filter tank
and ensure that the cover gasket is in place. Check the water level to ensure that the skimmer is not
inhaling the air.
•
Impeller clogged with debris
Turn off the power supplied to the pump and remove debris from the impeller. If you cannot clear the
debris, complete the following steps: Remove the left threaded screw bolts and O-ring seal. Remove,
clean, and reinstall the impeller. Clean the suction trap.
No water flow at the pump operation
•
No water flow at the pump operation
Check that the pump is rotating by viewing the fan on the back of the shift pump. If yes, check that the
pump impeller is properly installed.
•
Air leakage
Check the pipe connections and verify that they are tight.
•
Plugged or restricted pipes
Check that the filter or suction side pipe is blocked. Check whether the discharge pipe is blocked,
including partial shut-off valve or dirty pool filter.
