Always discount the pump from the electrical power source before handling. If the system fails
to operate pproperly, carefully read instructions and perform maintenance recommendations. If
operating problems persist, the following chart may be of assistance in identifying and correcting them.
Red light comes on at control
box
Overload trips at control box
and alarm buzzer or due to
high water level in basin
Yellow run light stays on
continuously
Circuit breaker trips with
control
Pump is noisy and pump rate
is low
Grease and solids have
accumulated around pump
and will not pump out of
basin.
1. This indicates some water has leaked
Replace the lower seal past the lower
seal and has entered the seal
chamber and made contact with
the electrode probe.
1. Impeller may be partically clogged with
foreign objects.
2. Component in the control box may be
faulty.
3. Pump has some damaged.
1. H-O-A switch may be in the hand position
2. Level control switch may have failed
causing pump to continue to operate
when water is below lower control.
3. Impeller may be partically clogged
causing pump to operate at very reduced
capacity.
4. Gate valve or check valve may be clogged
causing low pump flow.
5. Pump may be air clocked.
1. Excessive load probably caused by a short
in the motor or control box
2. If this condition happens after an electrical
strom, motor or control box may be
damaged by lightning.
1. Impeller may be partially clogged with
some foreign objects causing noise and
overload on the motor.
2. Impeller may be rubbing on wear ring due
to bent shaft or misalignment.
3. Pump may be operating too close to
shut-off
1. Lower control switch may be set too high.
2. Trash and grease may have accumulated
around floats causing pump to operate
erratically
1. Replace the lower seal
1. Check impeller for freedom of operation, security
and condition Clean impeller cavity and inlet of any
obstruction.
2. Check control box, if need repair it.
3. Check pump, if need repair it.
1. Reposition pump or clean basin as required to
provide adequate clearance for float
2. Disconnect level control. Set ohmmeter for a low
range, such as 100 ohms full scale and connect to
level control leads. Actuate level control manually
and check to see that ohmmeter shows zero ohms
for closed switch and full scale for open switch
(Float Switch)
3. Check impeller for freedom of operation, security,
and condition. Clean impeller cavity and inlet of any
obstruction
4. Remove and examine check valve for proper
Installation and freedom of operation
5. Loosen union slightly to allow trapped air to
escape. Verify that turn-off level of switch is set so
that impeller cavity is always flooded. Clean vent
hole.
1. Check out instructions given box before pulling
pump
2. Reset breaker by pushing completely down on
handle then back to ON position. If breaker trips
again in a few seconds it indicates.
1. Check impeller for freedom of operation, security,
and condition. Clean impeller cavity and inlet of any
obstruction.
2. If need replace shaft
3. Check if the pump is operating
too close to shut-off.
1. Check and reset the control switch
2. Run pump on hand operation for several minutes
with small amount of water running into amount of
water running into
basin to clean out solids and
grease.
