6.  Check the priming hole for obstruction. (Figure 1). 

Follow the cleaning steps listed below:

a.  Disconnect pump from power source.
b.  Remove the strainer.
c.  Remove the four (4) base screws (Figure 1).
d.  Remove the base and impeller plate.
e.  Use a pin or paperclip to clean the priming hole and air 

escape channel.

f.  Reinstall impeller plate, base, screws and strainer.

7.  If pump runs continuously, unplug the unit. Once unplugged, 

remove the strainer and check for debris stuck inside the 
sensor body (Figure 2). Remove any trapped leaves, debris 
or dirt.

8.  If the pump cycles on and off too often the electronic switch may need 

cleaning. Disconnect pump from power source, remove the strainer 
and turn the pump upside down. The sensor probe will be visible inside 

 

Do NOT use pump if any part of the switch 

  housing or probe is cracked, broken or missing.

PUMPING HEIGHT
When water is pumped to an elevated position, any volume that 
has not reached the discharge outlet can flow back through the 
pump when the pump shuts off. This back-flow can cause the 
water level in small areas to rise enough to re-start the pump. The 
check valve/hose adapter included is required in this situation. 
For proper operation, make certain the check valve is oriented as 
instructed on check valve body. 

 

 

In small areas a check valve is required to  prevent 

  backflow. Without a check valve the pump may 

cycle continuously and potentially wear out the pump components.

the switch housing. Clean inside the housing gently scrubbing with a 
small brush using soapy water. Then rinse thoroughly with clean water.

9.  When temperatures drop below freezing remove pump from service 

and store indoors to protect pump from damage due to ice. The 
pump has a unique protection circuit to protect the motor from a 
locked impeller condition possibly caused by debris buildup or 
from a “frozen” impeller situation caused by ice formation.  When 
the pump is activated and a locked impeller condition is detected 
the unit will automatically shutdown to protect the motor from 
overheating. The pump will continue this on/off cycle for a period 
of time to attempt to “free” the impeller until eventually the unit 
will remain off for a period of 12 hours checking twice a day for a 
“freed” impeller.  Once the pump is able to operate correctly the 
pump will resume normal operation. To reset this delay without 
waiting 12 hours momentarily unplug the pump.

Troubleshooting 
Chart

 

Electrocution Hazard! Pump starts automatically.  Disconnect the power before 

  attempting any repairs. Failure to follow WILL result in serious injury or death.

Symptom

Possible Cause(s)

Corrective Action

Pump will not 
start or run

1.  Tripped home electrical breaker
2.  GFCI tripped
3.  Low line voltage
4.  Defective motor
5.  Dirty switch
6.  Impeller obstructed
7.  Inlet screen or strainer clogged
8.  Priming hole plugged

1.   Reset breaker
2.   Check for damaged wiring or moisture
3.   Contact electrician
4.   Replace pump
5.   Rinse out switch with clean water (Figure 2)
6.   Remove strainer, base, and impeller plate (Figure1) check for debris; clean
7.   Clean inlet screen and debris strainer (Figure 1) 
8.   Clean hole, inside volute housing, with a pin or paper clip (Figure 1)

Pump starts and 
stops too often

1.  Backflow of water from piping
2.  Dirty switch
3.  Priming hole plugged
4.  Pump is sitting uneven on pool or spa 

cover

1.   Install or replace check valve 
2.   Rinse out switch with clean water (Figure 2)
3.   Clean hole, inside volute housing, with a pin or paper clip (Figure 1)
4.   Reposition pump so pump sits level on cover

Pump will not 
shut off or runs 
continuously

1.  Debris in switch
2.  Discharge height exceeds capability

1.   Rinse out switch with clean water (Figure 2)
2.   Reduce discharge height

Pump operates 
but delivers little 
or no water

1.  Impeller obstructed
2.  Priming hole plugged
3.  Obstructed hose
4.  Discharge height exceeds capability
5.  Strainer clogged

1.   Remove strainer, base, and impeller plate (Figure 1), check for debris; clean
2.   Clean hole, inside volute housing, with a pin or paper clip (Figure 1)
3.   Check for kinks, reposition hose or check for debris
4.   Reduce discharge height
5.    Unplug pump. Remove strainer and rinse with clean water to remove debris
