Motor hums but does not turn freely, can you turn the motor by removing the motor end cap?


no! You have to remove the pump end to find the shift, You may look between the pump and motor and find the shift splice and set screws that need to be tighted up.

Pump acts like it is froze up. It hums and smells like it is burning when it runs. It hums then shuts off, hums then shuts off?


Either you need a new start/run capacitor or the bearings have seized. If it's been running loudly recently, the bearings have probably seized. If not, the start capacitor is probably bad. This can sometimes happen when the motor windings start to develop a short. If you replace the capacitor and it blows again, you'll probably need a new motor.

Is any one else out ther with a Waterways 56 pump replacing them every 3 years also?


The UK versions of the Waterway pumps seem to be very reliable. The only known issue is with the Run/Start capacitors which tend to fail but they're easily replaced.

Over the years I've heard of many pumps being changed unnecessarily.

Was the pump working prior to the cleaning or had it been sitting dormant? The motor relies on a starting circuit within it to operate. One of the components can be bad or the pump can be siezed up.

Turn off the power and remove the back cover from the motor. Try to turn the shaft by hand. Is it free to turn? If so, the problem is inside the motor. If not, look for the obstrction.

A local electric motor repair shop can help you if you find damage in the motor and/or pump.

My Mustang pool motor by Waterway musts-120 is just humming when it is turned on. It is connected to a timer, but the pump is working fine, just the motor is humming. What do I do? Is my motor toast?


Check your loacl yellow pages for an electric motor repair shop. They may find it is fixable but could at least tell you if it is salvagable or not. Some even carry replacement motors at costs lower than the pool stores.

REASSEMBLED WET END OF WATERWAY PF401A22C-LEAKS- NEED DIAGRAM


I've never seen a reassembly diagram for this particular pump but I'm guessing that you've installed the mechanical seal incorrectly.

Where is it leaking from exactly?

Kind Regards,
Ian Kime.
