FAQS
Why is my pump running hot but out of power?
- This may be due to a lack of power due to the small size of the wire or poor connection. Check your user manual to ensure proper wiring.
- Your local power company may experience power outages, especially during heat waves. Restart the pump when the weather cools to confirm that the problem is indeed in the motor.
- Your pump has a thermal overload, which will shut down the motor and when it gets too hot, it will restart once it has cooled down. Check the air intakes of the motor to make sure they are free of debris. If debris blocks these vents, it will cause the motor to overheat and potentially shut down.
- Make sure your pump is located in an area with adequate drainage. Flooding from rain and other sources can cause the pumps to overheat and be cut off.
Why is my pump making noise?
- There is an audible cooling fan inside the motor. When installing the pump, it is recommended to carefully consider the location; Under the bedroom window may not be the ideal location.
- Vibration from the pump foot and base (where the pump is located) can cause the pump to make noise. A piece of old carpet or rubber between the base of the pump and the equipment pad can reduce noise.
- Make sure the pump is level and the suction line is not higher than the pump.
- Bearings may produce noise due to aging or high concentrations of chemicals and heat. Leaking pump seal may 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. Please contact your authorized dealer for repairs.
- Many times, pump noise can come from cavitation. There are two possible causes of cavitation, both of which are related to hydraulic power (water flow). The first is that the suction pipe size is too small. If the pipe is too small, the pump will need less water to function properly. Increasing the pipe size (increased water flow) or decreasing the impeller size (reduced water flow) can mute the pump. The second is that the pressure side of the system has little or no back pressure (the pump is a good example). It is recommended to add a valve or something else to increase the back pressure.
Why are air bubbles flowing into the pool from the reflux unit?
- If air returns to the pool, there may be a leak on the suction side of the pump. Please check the following items that may cause air to enter your system: You may need to contact an authorized Hayward dealer for repairs.
- Filter cover and O-ring. If loose, tighten it. If damaged, replace the gasket.
- The water level in the pool is low, causing water and air to mix into the skimmer.
- The skimmer weir can get stuck in an upward position, causing water and air to mix in the skimmer weir.
- Check drain plug on pump filter housing.
- Inspect all threaded fittings for leakage due to improper sealants or sealing procedures.
- Check the glued joint for poor bonding.
- Check all valves for possible leakage. Stem O-rings are a common suction leak point.
- Check and make sure there is no cavitation in the pump.
- Check pump housing for cracks.
Why can't my pump fill up?
- Pump suction side leakage.
- Check suction line to make sure there are no obstructions.
- Check that the impeller is still attached to the motor shaft. If the impeller has fallen off, it needs to be replaced.
- If the pump is installed some distance away from the pool or above normal deck level, it may take longer for the pump to start. For overhead installations, it may be necessary to install a check valve on the suction line for easier injection.
Can I start the pump without water?
Pool pumps should not be run without water. The pump seal assembly in the pump volute (the area between the filter basket and the pump motor) protects the pump motor from pool water. This sealing assembly gets hot and is then cooled by the pool water. If the pump is operated without water, the seals will overheat and melt, and if the pump is operated without water for a long time, the heat generated may damage the PVC pipe and other system components.
