Hayward Power-Flo LX Troubleshooting Suggestions
Motor Will NOT Start , What Can I Check For?
- Improper or loose wiring connections; open switches or relays; tripped circuit breakers, GFCI’s, or blown fuses.
- Manually check rotation of motor shaft for free movement and lack of obstruction. (See steps 4 & 5 of “Shaft Seal Change Instructions” in this manual.)
- If you have a timer, be certain it is working properly. Bypass it if necessary.
What Could Cause the Motor to Shut Off?
- Undersized wiring; loose connections; etc.
- Low voltage at motor or power drop (frequently caused by undersized wiring or extension cord use).
- Mechanical binding and electrical overload.
- If an extension cord is used for the power supply of the pump, it must be the proper gauge to handle the voltage. A thin, smaller gauge extension cord will create resistance and cause a voltage drop by the time the electricity reaches the pump. The pump will run very hot and the internal thermal overload switch will shut the pump down to protect it. If this continues to happen, it will burn out the motor and a replacement will be needed.
The Motor Hums, But Does NOT Start?
- Centrifugal switch stuck in OPEN position.
- Binding of motor shaft.
What Causes the Pump to Lose its Prime?
- The water level may be below the skimmer.
- Make sure pump/strainer housing is filled with water and the cover O-ring is clean, also be sure it is properly seated in the cover O-ring groove. Make sure strainer cover is locked firmly in position and properly lubricated.
- Make sure all suction and discharge valves are fully open and not blocked, that pool water level is at proper level, and that skimmer weir is not hung up or binded on skimmer wall.
- Block off to determine if pump will develop a vacuum. You should have 5”-6” of vacuum at the strainer cover (Only your pool dealer can confirm this with a vacuum gauge). You may be able to check by removing the skimmer basket and holding your hand over the bottom port with skimmer full and pump running. If no suction is felt, check for line blockage.
- If pump develops a vacuum, check for blocked suction line or dirty strainer basket, an air leak in the suction piping may be the cause.
- If pump does not develop a vacuum and pump has sufficient “priming water”: Re-check strainer housing cover and all threaded connections for suction leaks. Check if all hose clamps are tight. Check voltage to ensure that the motor is rotating at full RPM’s. Open housing cover and check for clogging or obstruction in suction. Check impeller for debris. Remove and replace shaft seal only if it is leaking.
What Can I Check For if there is Low Flow?
- Clogged or restricted strainer or suction line; undersized pool piping.
- Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). How to correct: Sand filters – backwash as per manufacturer’s instructions; D.E. filters – backwash as per manufacturer’s instructions; Cartridge filters – clean or replace cartridge.
- Air leak in suction (bubbles issuing from return fittings). Re-tighten using Teflon tape.
- Plugged or restricted impeller or impeller sheared off. Replace including new seal assembly.
What Causes a Noisy Pump?
- Air leak in suction piping causing rumbling in pump.
- Cavitation due to restricted or undersized suction line or leak at any joint, low water level in pool, and unrestricted discharge return lines. Correct suction condition or throttle return lines, if practical. Holding hand over return fitting will sometimes prove this point or putting in a smaller eyeball fitting.
- Vibration due to improper mounting, etc. Put a rubber pad under metal mounting feet.
- Foreign matter in pump housing. Loose stones/debris hitting impeller could be cause, remove any of the above.
- 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.
- Equipment base vibrating.
