5. Troubleshooting
Fault Cause Remedy
Difficult in starting
1. The supply voltage is too low
2. Phase loss
3. The impeller is jammed
4. The voltage drop of cable is too large
5. Stator winding is burnt out
1. Adjust the voltage to ±10% of the rated value
2. Check switch outlet and cable and plug
3. Fix the jammed part
4. Select and use reasonable cable
5. Insert winding again for overhaul
Low water output
1. The lift is too large
2. The mesh enclosure is blocked
3. The impeller is worn seriously
4. The immersion depth of electric pump is
shallow, with air sucked
5. The impeller reverses
1. Use the pump within the usable range of lift
2. Clear away water plants and other foreign matters
3. Replace the impeller
4. Adjust the immersion depth of electric pump, which
shall not be less than 0.5m
5. Exchange any two of the three phases
Stop running abruptly
1. Switch is off, or fuse is burnt out
2. The impeller is jammed
3. Stator winding is burnt out
1. Check whether the lift used or supply voltage meets
requirements and adjust it
2. Clear away foreign matters
3. Insert winding again for overhaul
Stator winding is burnt
out
1. Phase loss occurs to electric pump or
the running time is too long
2. Water leaks due to damage of
mechanical seal, resulting in turn-to-turn or
phase-to-phase short circuit
3. The impeller is jammed
4. Electric pump starts up frequently or
runs out of water too long
5. Electric pump is overloaded
Eliminate the faults, remove the winding and
insert the winding again according to the original
technical requirements, and apply insulating paint
by impregnating and drying, or send it to the
maintenance company for repair
