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.
