TROUBLESHOOTING
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. If none of the above work, refer to an Authorised Service Agent or another qualified professional.
Pump Will Not Prime
1. 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.
2. Fill the pump strainer/housing with water to the level of the pump inlet. Ensure that the cover gasket is clean, seated
correctly, and lubricated. Tighten the strainer cover hand knobs by hand only.
3. Make sure the pump strainer basket is clean.
4. 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 a 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).

4. An air leak in the suction side plumbing (bubbles issuing from the return fittings) Re-tighten or re-seal threaded suction
fittings with Teflon tape. Inspect other plumbing fittings and replace o-rings and tighten as required.
5. Motor bearings made unserviceable by wear, rust or continual overheating. Refer to authorised service agent.
6. Plugged, restricted or damaged impeller. Replace the impeller, including a new shaft seal assembly and slinger.
Motor Cuts Out
Your Hayward pump motor is equipped with
Automatic Thermal Overload Protection
. The motor will automatically shut-off before heat
damage build up can occur due to abnormal operating conditions. The motor will auto-restart when a safe heat level is reached. If the motor
fails to restart, switch the power off and contact an authorised Super II ECO Pump Service Technician.
Damaged Supply Cord
If the power supply cord is damaged it must be replaced by the manufacturer, its service agent or similarly qualified persons in order
to avoid a hazard.
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, etc.:
›
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 cowling 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.
