3. Open circuit 3. Check circuit breaker or fuse, and GFI reset button
The pump will not 4. Poor power source 4. Check circuit line wires and cable*
start or run 5. Low voltage 5. Check line wires and source voltage*
6. Locked impeller 6. Remove strainer and clear obstruction
7. Defective float switch 7. Replace float switch with new float switch
8. Defective pump 8. Replace pump with new pump
1. Locked impeller 1. Remove strainer and clear obstruction
Thermal protector 2. Incorrect power supply 2. Check power supply source and voltage
tripping or 3.
Overburdened due to heavy sand content in the 3. Use water filter or replace with a higher wattage
not functioning
water pump
4. Pump running continuously with no water present 4. Check float switch
Pump starts 1. Float switch mounted too low 1. Raise float switch
and stops too 2. Water backflowing from pipe 2. Install or replace check valve
