Hayward  - Pool Pumps - MaxFlow VS

MaxFlo™ VS


Product Description


Taking the first step in energy efficiency is simple with the new variable-speed MaxFlo™ VS. Offering up to 80% energy cost savings over single-speed pool pump alternatives via an integrated variable-speed drive and totally-enclosed, permanent magnet motor, MaxFlo™ VS is an ideal pool upgrade for those looking to reduce energy use and save money.


Variable-speed pool pumps are the ultimate way to save energy. Most other variable-speed models, however, are oversized when compared to medium-head pool pumps such as Hayward’s MaxFlo™ Series. The all-new MaxFlo™ VS is right-sized, particularly for applications with 40mm or 50mm plumbing, providing tremendous energy savings that result in an even faster return on investment.


MaxFlo™ VS provides customisable speed and priming time to match the needs of both aftermarket and new construction installations. Upgrade to MaxFlo™ VS and save energy and money!






  • Clean strainer basket regularly. Do NOT strike the basket to clean it. Inspect the strainer cover gasket regularly and replace it as necessary.

  • Hayward pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary.

  • Keep the motor clean. Ensure the air vents and fan are free from obstruction to avoid damage. Do NOT use water to hose off the motor.

  • Occasionaly, shaft seals must be replaced due to wear or damage. Replace with genuine Hayward seal assembly kit.


Do NOT use petroleum based lubricants on gaskets, o-rings, or plastic components. Use silicone based only.


*NOTE - Tighten the strainer cover lock ring and the union nuts by hand only (no wrenches). 



Benefits of operating at low speeds

  • Save electricity and money. A reduction in Pump Speed of 50% will reduce power consumption by up to 75% • Better filtration - the filter can often remove smaller particles when the water moves slower

  • Quiet operation, so therefore it is very unlikely to be intrusive to your neighbours

  • Reduced Total Dynamic Head - less stress on equipment (e.g. filter) which can extend equipment life


When determining the speed(s) to operate your pump, you must also take into account the minimum requirements for proper sanitation and equipment/water feature functionality.

It is recomended you filter (”turnover”) all the water in the pool at least once every 24 hours. Check with local requirements for the minimum turnover rate.


Running the pump at lower speed may require running the pump for a longer period of time in order to meet the turnover requirements for proper sanitation.


Equipment such as heaters, skimmers, and chlorinators require minimum flows to operate correctly. Refer to the individual equipment manuals for specific requirements for low flow operation.


After setting the pump speed(s), it is recommended you check all other equipment/water features are functioning as intended. For example, when running at low speed for daily filtration, verify that the water is adequately flowing over the skimmer weirs. Operate the pump at higher speeds for the shorter periods of time needed to operate a heater, water feature, times of increased bather load, ect.



Code - Indications


1 - Undervoltage on DC -Link


2 - Overvoltage on DC-Link


4 - Maximum temperature exceeded power module


5 - Over temperature motor


7 - Maximum current exceed


10 - Current Measurement Fails Permanently


20 - Overload During Start Up Process


64 - Short Circuit Failure


97 - Multiple Errors at the Same Time, i.e. Under voltage and Overload


98 - Communication Failure From controller




* Refer to the MaxFlow VS Owners Manual




Motor Will Not Start

  1. Ensure the power cord is plugged in and the power is switched on. If the pump still won’t start check the availability of power by plugging in another appliance and seeing if it will start.

  2. If the pump is controlled via a Chlorinator or Total System Controller, ensure that the controlling device is actually allowing the pump to start.

  3. Check for open switches or relays, tripped circuit breakers or blown fuses.

  4. Refer to an Authorised Service Agent or another qualified professional.


Motor Cuts Out

Your Hayward pump motor is equiped with Automatic Thermal Overload Protection. The motor will automaticly shut-off before heat damage buildup can occur due to abnormal operating conditions. The motor will auto-restart when a safe heat level is reached.


Pump Will Not Prime

  1. Ensure that the length of time that the 3000 rpm priming cycle runs for is sufficient. This time is factory set to 60 seconds but can be adjusted up to 240 seconds (see page six (6) for instructions how to change the length of time)*.

  2. Make sure all the suction and discharge valves are open and unobstructed, that the filter manual air relief valve is open, and that the pool water level is above all suction openings.

  3. Make sure the pump strainer basket is clean.

  4. Fill the pump strainer/housing with water to the level of the pump inlet. Ensure that the strainer cover o-ring is clean, seated correctly, and lubricated. Tighten the strainer cover lockring by hand only.

  5. Check for loose unions or damaged union o-rings on the suction side. Replace damaged o-rings and tighten the union nuts by hand only (no wrenches).


Low Flow - Generally

  1. Check for clogged or restricted strainer basket or suction line. If the suction line is blocked contact a qualified repair professional.

  2. The pool piping is under size. Correct the piping size.

  3. Check for a plugged or restricted discharge line of the filter, valve partially closed (high gauge reading). Sand filters - backwash as per manufacturer’s instructions; D.E. filters - backwash as per manufacturer’s instructions; Cartridg filters - clean or replace the cartridge as per the manufacturer’s instructions.

  4. An air leak in the suction side plumbing (bubbles issuing from the return fittings). Re-tighten or re-seal threadedsuction fittings with Teflon tape. Inspect other plumbing fittings and replace o-rings and tighten as required. 5. Plugged, restricted, or damaged impeller. Replace the impeller including a new shaft seal assembly.


Noisy Pump

  1. Cavitations caused by restricted or undersized suction line, an air leak at any joint, low water level in the pool, and unrestricted discharge return lines. Correct the suction condition or throttle the return lines, if practical. Holding your hand over the return fittings will sometimes prove this, or by putting in a smaller eyeball fitting.

  2. Vibration due to improper mounting, ect. Mount the pump on a level surface and secure the pump to the equipment pad. 

  3. Foreign matter in the pump housing or fan cowling. Loose stones/debris hitting the impeller or the motor colling fan could be the cause. Clean the pump housing and the fan cowling. 

  4. Motor bearings noisy from normal wear, rust, overheating, or water ingress due to a worn or damaged shaft seal. Contact a qualified repair professional to rectify.


Variable Speed Drive Error Codes

In the case that an internal failure has been detected, the Variable Speed Drive will turn the motor off and display an error code listed below. If more than one error has been detected the screan will flash between the errors.

The Variable Speed Drive is protected against overload and overheating. If such an error occurs, the VSD will automaticly try to restart the motor three (3) times while the display will show the message “RSTRT”. After failing the fourth (4) time to restart the display will show an error message “OLOAD”.

The cause of an error should be investigated and resolved before continuing normal operation of the pump. When the issue has been resolved, press the RUN/STOP key to clear the error message.
