Why won’t my pump power on?

• It is very important that your pump is located in an area that has adequate drainage to prevent flooding from rain and other water sources. Check to make sure the pump did not fail because of water damage.   Check the power (a volt meter is needed to check voltage), breakers, switches, etc., to ensure your pump is electrically powered.  Determining the voltage draw is very important.
•  If you have a timer or automated control system, ensure that it is properly working. Hayward recommends that you contact a certified electrician for any electrical repairs.  
  

Why is my pump running hot and powering off?

• This maybe caused by insufficient power due to an undersized wire or a poor connection.  Check your owner’s manual for proper wiring.
• Your local power company might be experiencing a power drop especially during a heat wave.  Restart your pump when the weather cools to confirm that the problem is really in the motor.
• Your pump has a thermal overload, which will shut the motor off when it gets too hot—it will restart once it has cooled down.  Check the air intake vents of your motor to ensure they are free of debris.  If debris is blocking these vents, it will cause the motor to run hot and possibly shut down.
• Make sure your pump is located in an area with adequate drainage.  Flooding from rain and other sources could cause a pump to run hot and cut off.
  

Why is my pump noisy?

• The motor has an internal cooling fan that can be heard. When installing your pump, it is advised to carefully consider the location; under a bedroom window may not be an ideal location.
• Vibration from the pump’s feet and the base (where the pump rests) can cause the pump to be noisy.  A piece of old carpet or rubber between the pump’s base and equipment pad might reduce the noise.
• Ensure the pump is level and the suction lines are not higher then the pump.
• The bearing(s) might be noisy due to age or high concentrations of chemicals and heat. A leaky pump seal could damage the front motor bearing.  It is very important to quickly repair any leaks around the pump to prevent extensive damage.  It is recommended that you replace the bearings or the entire motor.  Contact an Authorized Hayward Dealer for repair.
• Many times a noisy pump can come from cavitation. Cavitation has two possible causes, which are both hydraulically (water flow) related.  The first is that the suction piping is undersized.  If this pipe is undersized, the amount of water the pump requires to operate properly is reduced.  Increasing the pipe size (increase water flow) or dropping the size of the impeller (decrease water flow) can quiet the pump. The second is that there is little or no backpressure on the pressure side of system (water feature pumps are a good example).  Adding a valve or something to increase backpressure is advised.
• For all of the above, it may be necessary to contact an authorized Hayward dealer for assistance.
  
  

 

Why is my pump cutting off and on every 5-10 seconds?

• Hayward motors are factory wired for 240 volts unless the motor is 120 volts ONLY. Check the voltage of the incoming supply power and ensure the motor is wired or can be wired for this voltage (data plate on motor will help provide voltage and wiring information).  Also check for loose or badly connected wires.  Contact a certified electrician for repair.
  

Why are there air bubbles flowing into the pool from the return fitting(s)?

• If air is returning into the pool there might be a leak on the suction side of the pump.  Check the following items that maybe causing air to enter the system:  It may be necessary to contact an authorized Hayward dealer for repair.
• The strainer cover and O-ring.  Tighten if loose or replace gasket if damaged.
• Level of water in the pool is low causing water and air to mix into the skimmer..
• The skimmer weir may be stuck in the up position causing water and air to mix in the skimmer.
• Check the drain plugs on the pump strainer housing.
• Check all of the threaded fittings for leaks from improper sealants or sealing procedures.
• Check glued fittings for bad glue joints.
• Check all valves for possible leaks. Valve stem O-rings are a common suction leak point.
• Check and ensure the pump is not cavitating.
• Check pump housing for cracks.
  

Why is my motor running, but I do not see any water flowing?

• A dirty filter, blocked return line, or a valve that is shut or partially shut off on the return side of the pump can cause this problem.
• Check the strainer basket and make sure it is clean of debris.
• The pump’s impeller may be clogged if the pump is running but the pressure is very low on the filter.  Inspect and clean the impeller. Refer to your Hayward owners guide to answer any questions on this procedure.
• The pump may have lost prime or have a suction leak   Refer to 5 & 6 above.
  

Why has my electric bill significantly increased since I installed my pool?

• Electric rates have substantially increased over the past few years.  Ensure the time clock or automated control is correctly set.  Eight to ten hours a day is a good benchmark for circulation time, however, this will vary depending on the size of the pool and the horsepower of the pump.  Consult a Hayward dealer for the recommended filter time for your specific pool.
• As motors ages, their efficiency decreases.

Why won’t my pump fill with water (prime)?

• An air leak on the suction side of the pump.
• Check to make sure the suction line is free of obstructions.
• Check to make sure the impeller is still attached to the shaft of the motor.  If the impeller has broken off, it will need to be replaced.
• If the pump is installed a distance from the pool or is elevated above the normal deck level, the time needed to prime the pump could be longer. For elevated installations, a check valve may be needed on the suction line to allow for easier priming.
  

Should I buy a cover for my pump or motor?

• Covers can extend the life of a motor, however; make sure that the cooling vents on the motor are left unobstructed for proper air circulation. Motor covers are not required.
  

Do I need to oil or grease my Hayward motor?

• No. Hayward pump motors are permanently lubricated and sealed.
