Troubleshooting Chart - Back-up Pump

Symptom(s) Possible Cause(s) Corrective Action(s)

Pump will not

run

1. Connections not secure

2. Low battery

3. Float switch obstruction

4. Defective or blown fuse

1. Check all connections

2. Check battery and replace if low

3. Make sure nothing is interfering with the operation of the switch

4. Check internal fuse located inside the control box. Pull the charger from the wall

outlet and remove. If the fuse is blown, replace it with a 15 amp automotive type fuse

Motor hums but

pump won’t run

1. Defective battery

2. Obstructed impeller

1. Check battery and replace if low or defective

2. Unplug pump and check to see if impeller is free to turn. If impeller is locked,

remove the 4 screws on the bottom of the pump to release the housing around

the impeller. Remove the obstruction. Reassemble pump and reconnect

Pump runs but

pumps very little

or no water

1. Check valve missing or improperly

installed

2. Obstruction in discharge pipe

3. Pump not rotated 30˚

4. Pump air locked

5. Discharge pipe length and / or

height exceeds capacity of pump

6. Low or defective battery

1. Check to make sure a check valve is installed and functioning between primary

pump discharge and standby sump pump tee fitting

2. Check for obstruction and clear if necessary

3. Check that pump is rotated 30˚ in tee fitting in ESP15 Installation section, Figure 3,

on page 2

4. The impeller housing has a small hole on its side. This hole must be open for the

pump to prime. With the pump unplugged, remove the 4 screws on the bottom

of the pump to release the housing around the impeller. Clean out the hole and

replace cover

5. If discharge is too high, a separate line may be required with a lower discharge

height

6. Check battery and replace if low or defective

Pump cycles too

frequently

1. Main check valve located between the

discharge of the primary pump and

the back-up sump pump tee fitting or

the back-up sump pump flapper valve

not installed or working properly

1. Install check valve or repair as required

4. The control box contains a multi-

colored indicator light. When AC

power is present, the light will

indicate the charging state, and

not reﬂ ect actual battery voltage,

particularly with a defective battery.

In order for the indicator light to

provide an accurate reading, steps

“a” through “d” must be followed.

a. Unplug primary AC pump and

the charger--a power off alert

tone will sound for 30 seconds.

b. Lift and release the ﬂ oat switch

to activate the back-up pump.

c. When the back-up pump stops,

read the test light:

Green: Indicates battery is

charged.

Yellow: Voltage is low,

indicating battery is partially

charged.

Red: Battery is completely

discharged or defective.

d. Plug in charger and main AC

pump.

When AC power is out, and when

pump has been running, the light

will indicate battery status.

5. A chirping sound from the control

box will accompany the red light,

indicating that the battery may

require attention or replacement.

Voltage is only an indicator of battery

condition and may not reﬂ ect the

true condition of the battery. See

Maintenance for instructions on

assessing battery condition.

6. A single 30-second tone will

sound when power to the system

is interrupted. The unit will reset

automatically when power is

restored. A 3-second tone will

sound every time the pump starts.

Maintenance

ALWAYS

disconnect the electrical

supply before attempting to

install, service, relocate or

perform any maintenance. If

the power source is out of sight, lock and

tag in the open (off) position to prevent

unexpected power application. Failure to

do so could result in fatal electrical shock.

Only qualiﬁ ed electricians should repair

this unit. Improper repair could result in

fatal electrical shock.

1. Once a month, check battery

condition.

2. Unplug the wall charger.

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 chart

and correct problem. Repeat step 5.

BATTERIES

Dangerous hydrogen

gas can be released

from batteries while charging. Sparks

can ignite the gas in an enclosed space.

Wear safety goggles when connecting

batteries. Battery connections should be

made in a well-ventilated area.
