TROUBLE SHOOTING
CAUTION! Always disconnect the pump from the electrical power source before handling .
If the system fails to operate properly, carefully read instructions and perform maintenance recommendations
.
If operating problems persist, the following chart may be of assistance in identifying and correcting them :
MATCH "CAUSE" NUMBER WITH CORRELATING "CORRECTION" NUMBER.
NOTE: Not all problems and corrections will apply to each pump model.
PROBLEM CAUSE CORRECTION
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 (to isolate
cause, go to manual operation of pump).
2a. Float movement restricted.
2b. Switch will not activate pump or is
defective
3. Insufficient liquid level.
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.
14. H-O-A switch on panel is in "Hand"
position.
Pump hums but does not run 1. Incorrect voltage
8. Impeller clogged, loose on shaft, worn
or damaged, inlet plugged.
Pump delivers insufficient capacity 1. Incorrect voltage
4. Excessive inflow or pump not properly
sized for application.
5. Discharge restricted.
6. Check valve stuck closed or installed
backwards.
7. Shut-off valve closed.
8. Impeller clogged, loose on shaft, worn
or damaged, inlet plugged.
9. Pump may be air locked.
10. Pump stator damaged / torn.
16. Improper impeller face clearance
17. Three Phase units rotating incorrectly
Pump cycles too frequently or runs
periodically when fixtures are not in use. 6. Check valve stuck closed or installed
backwards.
11. Fixtures are leaking
15. Ground water is entering basin.
Pump shuts off and turns on independent
of switch, (trips thermal overload
protector).
CAUTION: Pump may start
unexpectedly. Disconnect power supply.
High AMPS
1. Incorrect voltage
4. Excessive inflow or pump not properly
sized for application.
8. Impeller clogged, loose on shaft, worn
or damaged, inlet plugged.
12. Excessive water temperature
16. Improper impeller face clearance
Pump operates noisily or vibrates
excessively. 4. Operating at too high / low of pressure
5. Discharge restricted.
8. Impeller broken or clogged.
13. Piping attachments to building
structure too rigid or too loose.
17. Three Phase units rotating incorrectly
1. Check all electrical connections for security. Have
electrician measure current in motor leads. If current is
or-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 adequate clearance for float.
2b. Disconnect level control. Set ohmmeter for a low
range, such as 100 ohms full scale and connect to level
control manually and check to see that ohmmeter shows
zero ohms for closed switch and full scale for open
switch. (Float Switch)
3. Make sure liquid level is at least equal to suggested
turn-on point.
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 and
condition. Clean impeller 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. Remove & examine for damage. Replace pump
stator if required.
11. Repair fixtures as required to eliminate leakage
12. Check pump temperature limits & fluid temperature.
13. replace portion of discharge pipe with flexible
connector.
14. Turn to automatic position.
15. Check for leaks around basin inlet and outlets.
16. Check impeller to volute face clearance (See
Service)
17. THREE PHASE UNITS: Check Proper Rotation
