Troubleshooting Chart

Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.

Symptom

Possible Cause(s)

Corrective Action

Pump will not run

1.   Poor electrical connection, blown fuse, tripped 

  breaker or other interruption of power; 

  improper power supply
2.   Motor or switch inoperative (go to manual 
  operation)
2a. Float movement restricted
2b. Switch will not activate pump or is defective
2c. Defective motor
3.   Insuffi cient liquid level

1.  Check all electrical connections for security. 
  Have electrician measure current in motor leads, 
  if current is within ± 20% of locked rotor Amps, 
  impeller is probably locked. If current is 0, 
  overload may be tripped. Remove power, allow 
  pump to cool, then re-check current.
2a. Reposition pump or clean basin as required to 
  provide adaquate clearance for float
2b. Disconnect level control. Set ohmmeter for a 
  low rang, such as 100 ohms full scale and 
  connect to level control leads. Actuate level 
  control manually and check to see that 
  ohmmeter shows zero ohms for closed switch 
  and full scale for open switch. (Float Switch)
2c. Check winding insulation (Megger Test) and 
  winding resistance. If check is outside of range, 
  dry and re-check. If still defective, replace per 
  service instructions.
3.  Make sure liquid level is above the pump
4.  Re-check all sizing calculations to determine 
  proper pump size.
5.  Check discharge line for restrictions, including 
  ice if line passes through or into cold areas.
6.  Remove and examine check valve for proper 
  installation and freedom of operation
7.  Open valve
8.  Check impeller for freedom of operation, 
  security and condition. Clean impeller cavity 
  and inlet of any obstruction
9.  Loosen union slightly to allow trapped air to 

 escape. Verify that turn-off level of switch is set 

  so that the suction is always flooded. Clean vent
  hole
10. Check rotation. If power supply is three phase, 
  reverse any two of three power supply leads to 
  ensure proper impeller rotation
11. Repair fixtures as required to eliminate leakage
12. Check pump temperature limits and fluid
  temperature
13. Replace portion of discharge pipe with flexible
  connector or tighten existing piping.
14. Turn to automatic position
15. Check for leaks around basin inlet and outlets

Pump will not turn off 

2a. Float movement restricted
2b. Switch will not activate pump or is defective
4.   Excessive inflow or pump not properly sized for 

application

9.   Pump may be air locked causing pump not to flow
14. H-O-A switch on panel is in "HAND" position

Pump hums but doesn’t run

1.  Incorrect low voltage
8.  Impeller jammed or loose on shaft, or inlet 
  plugged

Pump delivers insufficient capacity

1.  Incorrect low voltage
4.   Excessive inflow or pump not properly sized for
  application
5.  Discharge restricted
6.  Check valve partially closed or installed backwards
7.   Shut-off valve closed
8.  Impeller jammed or loose on shaft, or inlet 
  plugged
9.  Pump may be air locked causing pump not to flow
10. Piping fixtures leaking or discharge before the 
  nozzle

Pump cycles too frequently or runs periodically 

when f ixtures are not in use

6.  Check valve partially closed or installed backwards
11. Fixtures are leaking
15. Ground water entering basin

Pump shuts of f and turns on independent of

switch, (trips thermal overload protector). 

CAUTION!

Pump may start unexpectedly. 

Disconnect power supply.

1.  Incorrect low voltage
4.   Excessive inflow or pump not properly sized for
  application
8.  Impeller jammed or loose on shaft, or inlet 
  plugged
12. Excessive water temperature (internal 
  protection only)

Pump operates noisily or vibrates excessively

2c. Worn bearings, motor shaft bent
5.  Debris in impeller cavity or broken impeller
10. Pump running backwards
13. Piping attachments to building structure too 
  loose or rigid
