Troubleshooting - Hayward XE Series Owner's Manual

Motor does not restart right away after power cycling and the LED is blinking
1. When removing power, ensure the LED turns off completely by waiting at least 30 seconds before reapplying power to the pump.
Motor Will NOT Start
1. Check wiring according to the diagrams on page 8. Verify input voltage to the pump.
2. Be sure the pump is wired for the available field supply voltage/current according to the pump data nameplate.
3. Check for and correct any improper or loose wiring connections; open switches or relays; tripped circuit breakers, or blown fuses.
4. Manually check the rotation of the motor shaft for free movement and lack of obstruction. Correct if necessary.
Motor shuts OFF and LED is not Solid ON
1. Check for low voltage or power drop at the motor (frequently caused by undersized wiring). Contact a qualified professional to verify the electrical connec-
tions.
Motor Hums, But Does NOT Start
1. 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 and 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. Lubri-
cant 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.
Low Flow – Generally
1. Clogged or restricted strainer or suction line. Contact a qualified repair professional.
2. Undersized pool piping. Correct the piping size.
3. Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). Sand filters – backwash as per manufacturer's instructions; D.E.
filters – backwash as per manufacturer's instructions; Cartridge filters – clean or replace the cartridge.
4. Air leak in suction (bubbles issuing from return fittings). Re-tighten the suction and discharge connections using PTFE tape. Inspect other plumbing con-
nections, and tighten as required.
5. Plugged, restricted, or damaged impeller. Replace the impeller including a new seal assembly.
Noisy Pump
1. Air leak in suction piping, cavitations caused by restricted or undersized suction line or leak at any joint, low water level in pool, and unrestricted discharge
return lines. Correct the suction condition or throttle return lines, if practical. Holding your hand over the return fitting will sometimes prove this, or by put-
ting in a smaller eyeball fitting.
2. Vibration due to improper mounting, etc. Mount the pump on a level surface and secure the pump to the equipment pad.
3. Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause. Clean the pump housing.
4. Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal damage, which will allow chlorinated water to seep
into bearings wiping out the grease causing bearing to whine. All seal leaks should be replaced at once.
