Troubleshooting
Troubleshooting information for pump only. For other
questions or problems, please call FLOTEC Customer
Service at 1-800-365-6832.
Risk of electrical shock. Always unplug the
pump before handling it or making any adjustments.
Always wear rubber boots when there is water on the
floor and you must unplug the pump or make any
adjustments.
Risk of infections from pathogens in
pumped effluent. Wear rubber gloves when removing the
pump from the tank and soak it in chlorine bleach for at
least an hour before working on it or servicing it.
NOTE: An automatic thermal overload protects the motor.
Running the pump dry may overheat the motor and acti-
vate the overload protector until the motor cools.
Pump does not run or just hums.
1. Line fuse or circuit breaker may be off, blown or
loose.
2. Water level in tank may be too low to activate auto-
matic float.
3. Power cord plug may not be making contact in recep-
tacle.
4. If all symptoms check OK, motor is probably defec-
tive; replace pump.
Pump runs but delivers no water or only small
amount of water.
1. Check valve may be installed backward. Make sure
flapper will open away from pump (see Figure 4).
2. Discharge gate valve, if used, may be closed.
3. Pump may be air locked. Start and stop several times
by plugging and unplugging cord. Check vent hole in
pump case for plugging.
NOTE: The pump has a small air vent hole in the pump
body to let out trapped air. If this hole becomes plugged,
the pump may air lock. To break the air lock, clear the
hole with a small screwdriver.
As a secondary precaution in installations of this type, drill
a 1/16" hole in the discharge pipe inside the tank below
the check valve. The check valve should be mounted hor-
izontally above the pump discharge. Do not put the check
valve directly into pump discharge opening.
NOTE: In tanks where the pump is operating daily, air
locking rarely occurs.
4. The pump may be trying to lift water too high. The
pump cannot deliver water higher than 15' (vertical
lift (a long horizontal piping run may reduce the avail-
able lift due to friction in the pipe).

5. The inlet, impeller or pump body may be plugged up.
Unplug the pump; Put on rubber gloves, remove the
pump from the chamber, soak it in chlorine bleach for
at least one hour, and clean it out.
6. The pump impeller may be partially clogged, causing
the motor to run slowly, resulting in motor overload.
Unplug the pump; Put on rubber gloves, remove the
pump from the chamber, soak it in chlorine bleach for
at least one hour, and clean it out.
The fuse blows or the circuit breaker trips when
the pump starts.
1. The pump inlet may be clogged. Unplug and remove
the pump and clean out openings.
2. The impeller or pump body may be plugged or par-
tially plugged. Unplug the pump; Put on rubber
gloves, remove the pump from the chamber, soak it in
chlorine bleach for at least one hour, and clean it out.
3. The pump impeller may be partially clogged, causing
the motor to run slowly, resulting in motor overload.
Unplug the pump; Put on rubber gloves, remove the
pump from the chamber, soak it in chlorine bleach for
at least one hour, and clean it out.
4. The fuse size or circuit breaker is too small.
5. Defective motor: call FLOTEC customer service at
1-800-365-6832.
The motor runs for a short time, then stops.
After a short time it starts again. This indicates
tripping overload caused by symptom shown.

partially plugged. Unplug the pump; Put on rubber
gloves, remove the pump from the chamber, soak it in
chlorine bleach for at least one hour, and clean it out.
2. The pump impeller may be partially clogged, causing
the motor to run slowly, resulting in motor overload.
Unplug the pump; Put on rubber gloves, remove the
pump from the chamber, soak it in chlorine bleach for
