Troubleshooting (continued)
Problem Solution
The pump does not run. 1. The line fuse or circuit breaker may be off, blown or loose.
2. Water level in the tank may be too low to activate automatic float.
3. The power cord plug may not be making contact in the receptacle.
4. If all symptoms check OK, the motor is probably defective. Replace the pump.
The pump runs but delivers no water
or only a small amount of water.
1. The check valve may be installed backward. Make sure the flapper will open away from the
pump (see Figure 4).
2. The discharge gate valve, if used, may be closed.
3. The pump may be air locked. Start and stop several times by plugging and unplugging the
cord. Check the vent hole in the 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 1/8 in. hole in the discharge
pipe inside the tank below the check valve. The check valve should be mounted horizontally
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 ft. (vertical lift (a long horizontal piping run) may reduce the available 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 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.
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. The motor is defective. Call customer service at1-844-241-5521.
The motor runs for a short time, then
stops. After a short time it starts
again. This indicates tripping overload
caused by symptom shown.
1. The inlet, impeller or pump body may be plugged or 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 dilute chlorine bleach for at least one hour, and clean it out.
3. The motor is defective. Call customer service at 1-844-241-5521.
