I am in Australia, and my 2HP aquaflow pump XP2 (model 06615168-1) hums on start up and eventually clicks off without pumping. The impellar and the shaft spin freely when I turn the shaft .What could the...

The Aquaflow pumps were the old workhorses and I still see some here in the USA that have been working for over 20 years. The first thing to do is see if the impeller turns freely just with your fingers. You may either take the lid of and stick a finger in the hole in the pot going toward the motor and try to spin the impeller, or on this pump you can reach the motor shaft through the holes in the motor mounting bracket. If the impeller spins freely, you most likely have a blown or open motor start capacitor. This is located under the little dome looking cap on top of the motor. At the very worst you would need to replace the entire motor but the pump should still be OK. This pump uses a keyed shaft motor and you need a long hex wrench to loosen the 3 set screws on the shaft extension. Not the easiest pump to work on but not rocket science either. Hope this helps.

Water pump, radiator doesn't have good flow. radiator is dirty on the outside. These are 3 possibilities The pumps impeller can become loose, it will give you enough water movement at idle, but under a load it starts to spin on the shaft. and the hotter it gets the more it will spin on the shaft.

My washer wont spin

Hello there and thank you for choosing fixya
This can be a rather easy fix or it can be a nightmare so i will post everything i have here for you to check ok
It doesn't spin It doesn't pump or spin
If it doesn't pump water out or spin, check to see if the motor is running, then proceed as follows:
If the motor is running, your washer probably has a frozen pump pulley or a broken pump belt. To check the pulley, remove the pump from the washer and try to rotate the pulley manually. If it doesn't turn freely--if it's frozen or stiff--replace it. If the pump belt is broken or looks quite worn, replace it--but be sure to check the pump pulley before you change the belt.
If the motor isn't running, the lid switch may be defective. If so, the washing machine can't spin and may not function at all. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washing machine to get to the switch. If it's defective, you need to replace it.
It pumps, but doesn't spin
If your washer pumps out the water but doesn't spin, check these:
The lid switch may be defective. If it is, the washing machine doesn't spin. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washing machine to get to the switch. If it's defective, you need to replace it.
The motor coupler may be broken. Many Whirlpool®-manufactured washers use a small, relatively inexpensive motor coupling. It's plastic and rubber and is mounted to the shaft of the motor on one side, and to the transmission on the other. Over time, the coupler wears out and fails. You may need to replace it.
A belt may be broken. Many washing machines have one or two belts. If a belt is broken or badly worn, you need to replace it with a genuine belt from the manufacturer. (Some washing machine belts are designed with special characteristics not found in automotive belts.)
The clutch may be worn. If your washer is a GE, it may use a clutch to come up to the proper spin speed. As the clutch wears out, it may prevent the unit from spinning well or at all. If the clutch is worn, you need to replace it. For this job, you probably want to hire a qualified appliance repair technician.
The drive motor may be defective. Many washer brands use a reversing motor. For agitation the motor runs in one direction, for spinning and draining, the other. It's possible for a motor to burn out in one direction and continue to operate in the other. If this happens, you need to replace the entire motor.
The transmission may not be shifting properly. Older washers produced by Whirlpool® have a transmission with an electro-mechanical shifter. If the shifter becomes even partially defective, the unit may drain the water but not spin. This is a complex system, if your washer has a shifter problem, you may want to hire a qualified appliance repair technician to repair it.
The spin bearing or basket drive may be worn or seized. These components allow the inner tub to spin freely inside the outer tub. When this is the problem, you usually hear a loud sound during the spin cycle. Call a qualified appliance repair technician.

If the water is pumping out fine you may need new shocks. But if it is slow pump the shaft on the pump is loose and causing the noise and possibly the spin issue. If it is loud when it does go into a spin (sounds like a jet engine) you have bad bearings. Big bucks to fix.

Trying to replace seals for a hayward sump pump and can't remove inpeller

Thank you for posting your question here on

Removing the impeller requires you lock the shaft as you turn the impeller off counter-clockwise. You will also need to check for an impeller screw in the center of the impeller inlet. If a screw is present they are usually left hand thread. Back out the screw first, then proceed to remove the impeller.

To lock the impeller you will have to remove the motor end cover or a cap covering the shaft end depending on which version your particular motor has. Look at the end opposite the pump and imagine a shaft from one end to the other right in the center.

Once you remove the cover you will see a slot for a screwdriver, a flat for a wrench, a hex hole for a hex key or some combination of these. Lock the shaft and spin off the impeller. Some are so tight you will end up breaking them in the process. Simply replace it and the seal. Be sure the motor shaft is in good enough condition to allow the new seal to work properly. If too much shaft material has rotted away the new seal will leak soon after it is installed; you would need a new motor at that point.

Agitator and spin did not work on final spin cycle--pump works--11 year old washer--is it worth trying to fix?

yeah this is an easy fix drive couple it connects the motor to the transmission cost about 9 dollars if you do the job yourslef simpl unpug the machine
remove the front cover that covers the drum
feel around inbetween the motor and the transmission you should feel a rubber bushing with three teeth if these teeth are busted in which they usually are then you replace your drive couple and u go about that by
removing the retainin clips around your pump then moving pump to the side no need to disconnect fully. next remove the upper and lower screws holding the retaining clips on the upper and lower part of the motor. disconnect wireing harness. then use a flat screwdriver to lift on the upper retaining clip and do oppiste on lower one make sure you hold the motor up with one hand while doing this then remove motor you will see the rubber bushing as well as the plastic drive couple ( note make sure when you order the new drive couple it is the one with the metal shaft ring and not the 100 percent plastic one or ull be doing the same job within two years putting it back together is easy just align the drive couple on the rear shaft and lightly tap it back onto the shaft use a 1/2 or 9/16 deep well to do this then align the rubber bushing next is to align the other part of the couple onto the motor and reinstall the motor then reinstall the pump then reconnect the harness to the motr then put your cover back on and your machine is done hope this helps

I just drained my hot tub to fix a leak and now one of my pumps won't work. It makes a humming noise for a second then it shuts off. Then repeats the humming noise for a second and shuts off.

It sounds as though the pump is jammed. You will have to loosen the pump somehow. The motor is trying to work but with the jam, it goes off on overload. The motor sounds good, just need to loosen the pump. Good luck...Lee
