9. Troubleshooting
9.1. General Problems
• Motor Will NOT Start:
1. Make sure the terminal board connections agree with the wiring diagram on the pump data plate label.
2. Be sure the pump is wired for the available field supply voltage.
3. Check for and correct any improper or loose wiring connections; open switches or relays; tripped circuit
breakers, or blown fuses.
4. Manually check rotation of the motor shaft for free movement and lack of obstruction. Correct if necessary.
• Motor Shuts OFF:
1. Check for low voltage or power drop at the motor (frequently caused by undersized wiring). Contact a
qualified professional to verify the electrical connections and that the voltage is within +/- 10% of the motor
nameplate voltage rating.
• Motor Hums, But Does NOT Start:
1. Check power supply voltage. Contact a qualified professional if the voltage is more than 10% lower than the
motor nameplate voltage rating.
2. Impeller jammed with debris. Have a qualified repair professional open the pump and remove the debris.
• Pump Won't Prime:
1. Empty pump/strainer housing. Make sure the pump/strainer housing is filled with water & the cover o-ring
is clean. Ensure the o-ring is properly seated in the cover o-ring groove. Ensure the o-ring sealing surface is
lubricated with “Jack’s 327” and that the strainer cover is locked firmly in position. Lubricant will help to
create a tighter seal.
2. Loose connections on the suction side. Tighten the pipe/union connections.
NOTE - Any self-priming pump will not prime if there are suction air leaks. Leaks will result in bubbles
emanating from the return fittings on the pool wall.
3. Leaking O-ring or packing glands on valves. Tighten, repair, or replace the valves.
4. Strainer basket or skimmer basket loaded with debris. Remove the strainer housing cover or the skimmer
cover. Clean the basket, and refill the strainer housing with water. Tighten the cover.
5. Suction side clogged. Contact a qualified repair professional. You should have 5” - 6” of vacuum at the
strainer cover (your pool dealer can confirm this with a vacuum gauge). You may be able to check by
removing the skimmer basket and holding an object over the bottom port with the skimmer full and the
pump running. If no suction is felt, check for line blockage.
a. If the pump develops a vacuum, check for a blocked suction line or a dirty strainer basket. An air
leak in the suction piping may be the cause.
b. If the pump does not develop a vacuum and the pump has sufficient “priming water”:
i.
Re-check the strainer housing cover and all threaded connections for suction leaks. Check
if all system hose clamps are tight.
ii. Check voltage to ensure that the motor is rotating at full rpm’s.
iii. Open the housing cover and check for clogging or obstruction in suction. Check the
impeller for debris.
iv. Remove and replace the shaft seal only if it is leaking.
