Troubleshooting

WARNING: Before servicing a pump, always shut off the
main power breaker and then unplug the pump. Under
flooded conditions, make sure you are not standing in water
and that you are wearing insulated protective sole shoes.
Contact your local electric company or a qualified licensed
electrician for disconnecting electrical service prior to pump
removal.
Problem
The pump does not run and makes a humming
sound.
The pump runs but does not deliver water.
The pump runs and pumps out sump, but does not
stop.
The pump runs but only delivers a small amount of
water.
The fuse blows or circuit breaker trips when the
pump starts.
The motor runs for a short time and then stops.
CAUTION: Call an electrician when in doubt. The pump
should be connected to a separate 15 A circuit breaker or
15 A fuse block. Note that plugging into existing outlets may
cause low voltage at the motor. This could cause blown
fuses, tripping of motor overload or a burned out motor.
Probable Causes and Solutions
□
The line circuit breaker is off, or the fuse is blown or loose.
□
The water level in the basin has not reached turn-on level as indicated in
the Installation Requirements drawing.
□
The pump cord is not making contact in the receptacle.
□
The float is stuck. It should operate freely in the basin.
□
If all of the above are OK, then the motor could be malfunctioning.
□
Check if the check valve is installed backwards. The arrow on the check
valve should point in the direction of flow.
□
The gate valve (if used) may be closed.
□
The impeller or volute openings are fully or partially clogged. Remove the
pump and clean.
□
The pump is air-locked. Start and stop several times by plugging and
unplugging the cord. Check for clogged vent hole in the pump case or
discharge pipe and/or no vent hole in the pump case or discharge pipe.
□
The inlet holes in the pump base are clogged. Remove the pump and clean
the openings.
□
The vertical pumping distance is too high. Reduce the distance or change
the discharge fittings of the pump.
□
The float is stuck in the up position. Be sure the float operates freely in the
basin.
□
The float switch is defective. Replace the float switch.
□
The pump is air-locked. Start and stop several times by plugging in and
unplugging the cord. Check for a clogged vent hole in the pump case.
□
The vertical pumping distance is too high. Reduce the distance or change
the discharge fitting of the pump.
□
Inlet holes in the pump base are clogged. Remove the pump and clean the
strainer and openings.
□
The impeller or volute openings are fully or partially clogged. Remove the
pump and clean.
□
The pump impeller is partially clogged, causing the motor to run slowly and
overload. Remove the pump and clean.
□
The motor stator may be defective.
□
The fuse size or circuit breaker may be too small (must be 15 A).
□
The impeller or volute openings are fully or partially clogged. Remove the
pump and clean.
□
The inlet holes in the pump base are clogged. Remove the pump and clean
the openings.
□
The pump impeller is partially clogged, causing the motor to run slowly and
overload. Remove the pump and clean.
□
The motor stator may be defective.
□
The impeller or volute openings are fully or partially clogged. Remove the
pump and clean. Also clean the strainer if one is installed.
