General Pump Troubleshooting

Blocked Impeller

WARNING: Before servicing the pump, switch off the circuit breakers at the power source. Severe personal injury or death 
may occur if the pump starts while your hand is inside the pump.

1. Turn OFF the pump. Switch off the circuit breaker to the pump motor.

2. Remove the pump lid and strainer basket.

3. Look inside pump for debris. Remove any debris found inside.

4. Replace the strainer basket and lid.

5. Switch on the circuit breaker to the pump motor.

6. Turn ON the pump, see if the problem is solved. 

7. If the impeller is still blocked with debris and it is not possible to remove the debris using Steps 2 - 4, the pump will need 
to be disassembled in order to access the inlet and outlet of the impeller.

Removal and Replacement of the Impeller and/or Mechanical Seal

WARNING: Before servicing the pump, switch off the circuit breakers at the power source. Severe personal injury or death 
may occur if the pump starts while your hand is inside the pump.

1. Turn OFF the pump. Switch off the circuit breaker to the pump motor. If you are not replacing the motor, do not disconnect 
the electrical wiring.

Problem

Possible Cause

Solution

1. Pump will not prime.

A. Suction air leak 

B. No water in pump.

C. Closed valves or blocked lines.

D. Low voltage to motor.

Make sure see-through lid and o-rings are clean 
and properly positioned. Hand tighten see-
through lid. Tighten all pipes and fittings on 
suction side of pump. Be sure water in pool is 
high enough to flow through skimmer.

Make sure strainer tank is full of water.

Open all valves in system. Clean skimmer and 
strainer tank. Open pump and check for clogging 
of impeller.

Check voltage at motor. If too low, pump will not 
run.

2. Motor does not turn

A. No power to motor.

B. Pump jammed

Check that all power switches are on. Be sure 
fuse or circuit breaker is properly set. Time set 
properly? Check motor wiring at terminal.

With power off, turn shaft. It should spin freely. 
If not, disassemble and repair.

3. Low flow

A. Dirty filter

B. Suction Leak

Back wash filter when filter pressure is high, or 
clean cartridges.
