Probable Causes Corrective Action
Correct cause for high amperage, such as low voltage or excessive
pumping.
Check electric wiring and motor for short circuits and correct.
Remove pump case and check for debris.
Check complete suction line and all fittings for air leaks and verify
foot valve has adequate submergence.
Take to an authorized motor shop for repair or replacement.
Check suction line and foot valve for leaks. Make sure that water
level has not dropped to uncover suction inlet. Prime pump.
Clear obstructions from suction and discharge lines.
Interchange any two of three wires either at the motor or starter.
Correct incoming power to match motor nameplate requirements.
Clean or replace impeller.
Reduce system head (back-pressure on pump) or resize pump.
Locate pump closer to the water source, increase pipe size or resize
pump.
Open valves to reduce possible restrictions.
Clear obstructions from discharge line.
Correct to proper rotation.
Remove pump case and check for debris.
Close down discharge valve to increase pressure and throttle back
flow rate.
