Problem Possible Cause
1. Pump is not plugged in
2. Water is not high enough to activate the pump
3. Open circuit
The pump will not 4. Poor power source
start or run 5. Low voltage
6. Locked impeller
7. Defective float switch
8. Defective pump
1. Locked impeller
Thermal protector 2. Incorrect power supply
tripping or 3. Overburdened due to heavy sand content in the
not functioning water
4. Pump running continuously with no water present
Pump starts 1. Float switch mounted too low
and stops too 2. Water back flowing from pipe
frequently 3. Malfunctioning float switch
1. Clogged or frozen discharge
2. Blocked intake strainer
3. One or both of the floats is obstructed and cannot
drop down
Pump will not
shut off
4. Defective float switch
5. Check valve is stuck or installed upside down
1. Check valve on secondary pump will not close and
water re-circulates within the system
2. Partially blocked impeller
Insufficient or no 3. Clogged or frozen discharge
water volume 4. Broken or leaking pipe
5. Low power voltage
6. Check valve is stuck or installed upside down
Abnormal sound 1. Check valve on secondary pump will not close and
or vibration water re-circulates within the system
2. Blocked intake screen
*Consult a licensed electrician
Corrective Action
1. Plug pump in properly (see instructions)
2. Make sure float switch is positioned properly
3. Check circuit breaker or fuse, and GFI reset button
4. Check circuit line wires and cable*
5. Check line wires and source voltage*
6. Remove strainer and clear obstruction
7. Replace float switch with new float switch
8. Replace pump with new pump
1. Remove strainer and clear obstruction
2. Check power supply source and voltage
3. Use water filter or replace with a higher wattage
pump
4. Check float switch

3. Replace float switch with new float switch
1. Clear blockage or thaw frozen line
2. Clear debris from intake strainer
3. Clear debris from inside the float cage (Loosen nut
on top of float, then remove c-clip on bottom of
float. Remove debris. Tighten nut on top of float,
then replace c-clip on bottom of float.) When
reassembling the float, the magnetic strip on the

4. Replace float switch with new float switch
5. Reverse or replace check valve. Make sure the
check valve is installed with the flow arrow pointing
up and out of the pit.
1. Replace the check valve on the secondary pump
2. Remove strainer and clear obstruction
3. Clear blockage or thaw frozen line
4. Repair piping
5. Check power voltage, wires and cable condition
6. Reverse or replace the check valve. Be sure
check valve is installed with flow arrow pointing up
and out of the pit
