Troubleshooting Chart - Primary Pump
Symptom Possible Cause(s) Corrective Action
Pump will not
start or run
1. Blown fuse
2. Low line voltage
3. Defective motor
4. Impeller
5. Defective switch
1. If blown, replace with proper sized fuse or reset breaker
2. If voltage is under 108 volts, check wiring size
3. Replace pump
4. If impeller will not turn, remove housing and remove blockage
5. Check / replace switch
Pump starts and
stops too often
1. Backfl ow of water from piping
2. Incoming water is draining on
sensor face
1. Install or replace check valve
2. Position pump switch away from the inlet so switch is clear
from incoming water (see Figure 1)
Pump will not
shut off or
thermal protector
turns off
1. Obstacle in piping
2. Low Line Voltage
3. Too many appliances on circuit
4. Dirty water sensor
5. Incoming water is draining on
sensor face
6. Defective switch
1. Remove pump and clean pump and piping
2. If voltage is under 108 volts, check wiring size
3. Install pump on dedicated circuit.
IMPORTANT: Do not use extension cord to power pump.
4. Clean sensor face (see Figure 3)
5. Position pump switch away from the inlet so switch is clear
from incoming water (see Figure 1)
6. Replace switch
Pump operates
but delivers little
or no water
1. Plugged impeller
2. Check valve installed backwards
3. Pump airlocked
4. Low line voltage
1. Clean out impeller
2. Reverse position of check valve
3. Drill 1/8” hole in discharge line between pump and check valve
4. If voltage is under 108 volts, check wiring size
Gurgling sound
from pump at
end of cycle
1. Air injested into pump
2. Time required for pumping is less
than 4 seconds
1. Wipe off surface of sensor (see Figure 3)
2. Additional run time will not damage pump
3. For batteries with top caps that
can be removed, the electrolyte
level should be checked and fi lled
to manufacturer’s specifi cations.
The charge for each cell should
be checked with a hydrometer. A
specifi c gravity of 1.265 indicates
the battery is at full charge. If the
specifi c gravity of any of the cells
varies more than .050, the battery
should be replaced.
NOTE: An inexpensive hydrometer
can be purchased at an automotive
parts dealer.
4. Inspect the terminals and clamps
for corrosion and tightness. Clean
and tighten as required.
5. Unplug the main pump and fi ll
sump with water until back up
pump turns on. Repeat process two
times to be sure pump is operating
normally.
6. If pump operates normally,
plug charger into wall outlet,
turn on main pump. If pump
fails to operate normally, see
Troubleshooting guide and correct
problem. Repeat step 5.
