TROUBLESHOOTING CHECKLIST
The following steps are for service and cleaning of the pump;
1.
Pump does NOT run or hums
Pump plug and liquid level control plug not securely fastened together.
Push plugs together tightly
Liquid level control inoperative. Test level control by plugging pump cord directly into wall outlet. If pump operates,
float tether requires adjustments or should be replaced
Submerse pump in a disinfectant solution (Clorox or Chlorine) for at least one hour before disassembling pump.
Liquid level control trapped below water level. Free and reposition so that its motion is unobstructed.
Thermal overload may have tripped. Disconnect from power source for 30 minutes to allow motor to cool. Check for
cause of overheating and overloading.
2.
Pump will NOT stop running
Liquid level control caught on basin sides or pump. Free float and reinstall it so that its motion is unobstructed.
3.
Motor runs, but does not pump sufficient (or any) water
Pump is air-locked. Run pump through several quick on/off cycles by plugging and unplugging pump cord. Detach
from piggyback plug first.
Impeller, volute and/or suction opening is plugged. Remove volute and clean.
Check valve or shutoff valve plugged. Remove check valve and clean. Open shutoff valve fully.
Check valve may be installed backwards or shutoff valve is closed. Adjust as required.
Discharge piping is too small. Replace with piping of size equal to or greater than pump discharge.
Pump is undersized for application.
4.
Pump starts and stops frequently
Check valve is stuck open. Water in discharge line is refilling basin after pump stops and is short-cycling the pump.
Remove check valve and clean thoroughly.
