Hayward Pool Pump Troubleshooting [2021]

The Hayward is a brand that is well renowned for manufacturing the world’s best pool pumps. They use sand or diatomaceous earth (DE) for filtering water. If you maintain your Harvard pool pump nicely, they work remarkably without any troubles and hassles. There may be some reasons which may lead to the malfunctioning of the pool pump.

Some of the problems and related solutions are mentioned in the article below.

Check The Hoses

Any kind of dripping hose can cause the water to drip, and it is a must to tighten the hose connections properly. If the water is dripping from the hose, it will invite air into the system and be a hurdle for the flow of water. All sorts of filters need an environment that supports vacuum, and malfunction is caused if the air enters it. Before troubleshooting, check the hoses properly.

A Loud And Screeching Pool Pump

The pump may be making noise as if rocks are running in the basket of the pump. The basic reason is that the pump is water-starved, and while it struggles to get water, it makes all the noise. There may be a few attributes related to this screeching noise, and clogging due to debris may also be one reason. You should check the suction lines, skimmer, and worn bearings if the noise persists. All these should be replaced or repaired, whatever is suitable should be done.

In case your pump is too powerful, then switching on to a downgraded one with less power is the alternative to avoid future problems. You can switch over to an older pool pump if troubleshooting consumes time.

Water Leakage From The Pool Pump

Due to a pressure-side leak, the pool pump may lead to water leakage. The impeller housing O-ring, the shaft seal, should be inspected. The worn or cracked O-ring should be repaired or replaced. It is advised to keep a go-kit handy with you, for replacing necessary and worn out parts in an emergency.

Prime The Pump

If your pool pump basket does not fill with water. Then follow the following:

  • The power to the pump should be disconnected and the diverter valve should be moved in order to turn off the main drain.

  • Any kin of existing pressure should be relieved. This can be done by turning the air relief valve counter-clockwise and wait till the pool filter gauge reads zero.

  • The pump lid should be removed, and any kind of debris should be cleaned from the pump basket. Later, fill it with water using a garden hose. After this, the pump lid should be replaced and the diverter valve should be open so that the water returns to the pool.

  • You should wait till the water starts coming out of the relief valve. Close it after that, and after one minute the water will be flowing freely in the strainer box at the pump top.

  • Any kin of existing pressure should be relieved. This can be done by turning the air relief valve counter-clockwise and wait till the pool filter gauge reads zero.

  • Still issues related to water flow then restart the process again from the first point.

Between the main drain and the skimmer, the diverter valve should be switched back to half way. If the pool pump is not primed, then the impeller should be inspected for any dirt or debris. The filter pressure should also be checked if the psi reading goes above 10, of the pool filter.

The Pool Pump makes a Humming Noise

If you hear any kind of humming noise, and the pump causes trouble while starting then checking the impeller for any clogs due to debris is must. Building debris may lead to clogging and blocking of the impeller and thereby disabling it.

Turn off the pump, remove the screws from the middle (pump body) for proper inspection. After removing the screws, the assembly should be pulled out of the housing and the gasket should be removed from the impeller. Now remove all the debris and re-assemble everything.

The Pool Pump is Sucking in Air

An airtight equipment is a must and any kind of leak will make the pump suck air, and that can be quite problematic. Firstly, check the pump lid, and if it is improper then it will suck air and prevent the pump from priming. Where the pipe enters the pump, it should be checked in case nothing works out still. Also check the valve stem on any of the suction valves, and the plumbing on the pump’s suction side, before the impeller, O-rings, and gaskets.

Any kind of leaks, cracks, old fittings, should be replaced or repaired as required. May be still you are not able to trace any leaks, then use a small trick by spraying shaving foam and the leak will be detected.

The Pool Pump Motor is Working improperly

If the motor is not running or causing troubles while running then a couple of things need to be monitored. A humming noise and no proper start-up then the capacitator may be faulty. The capacitator gives a jolt of electricity for starting the pump. Let us be clear that without a jolt, start-up doesn’t take place properly. Replacing the capacitator is a good idea, and should be done by an expert or a professional. It has lot of power, so replacing a capacitator is to be done carefully. If you have an old pump then replace the motor.

If the pump doesn’t turn up properly, the overheating may be the cause. It is better to use the pump in the night to prevent overheating. Still things don’t work then check the vents on the bottom of the motor, as there may be something inhibiting the fan. Lastly, the only solution left is to replace the motor or the pump.

The Flow Rate of the Pool Pump is Low

If the pump’s flow rate is dropped, then it should be ensured that there is no blockage in the filter or the pump. Checking the filter gauge is advised and a psi above 10 calls for cleaning the filter in order to minimize the pressure. The flow back to the pool pump should be reset.

The pump basket and impeller should be inspected for debris or dirt that may be clogging the flow of water. Pump should be turned off and screws should be removed from the middle for removing debris. Reassembling is required at this moment.

Backwash the Filter

Diatomaceous earth is regenerated by the Hayward filters when pumped with the handle. The pool is then cleaned by the repositioning of the DE. In case of a sand filter, the backwashing should be performed by following the instructions of the manufacturer. The filter should be turned on for checking whether the problem is resolved or not.

Replace the Sand or DE

If the problem is not solved then the filter should be cleaned and draining is needed. After opening the filters should be washed properly with a garden hose, and the filter fingers or cartridge should also be washed according to the model requirements. Reassemble the filter by adding a new diatomaceous earth. This should be done through the pool skimmer.
