SOURCE: no suction

Ok first thing to do is remove & clean the 2 piece premotor filter or purchase new.

Now remove soleplate from bottom of machine to do this rotate the 3 plastic screws to unlock position. Lift sole plate off now remove any blockagers or fluff that may be built up over the brush roller.
Remove hair from brush roll using scissors.

Check short clear hose for blockages & any damage rips or tares if it is damaged purchase new hose.

Now look at belts & rotate brush roller it should turn relatively easy if it is difficult to turn by hand remove the brush roller & pull off the end caps the axle will come out with one of the caps.
Check the roller bearings clean away dust build up replace end caps & axle spin roller holding on to end cap if freely to spin refit back on to machine.

If its stiff to rotate you will need new roller.

Now pull off the 2 inspection ports check them for bits of paper etc especialy the (U) shaped port at bottom rear of machine this can contain pens pencills stones all sorts of items that hinder the suction.

Now check the long flexi hose & metal wand for any obstructions.

If after all this machine is still not working correctly go to this site http://dysonmanuals.llc.nu/

On this site you will find Dyson service manuals covering poor suction, clutch,motor, etc.

SOURCE: motor or beater bar making horrible noise

The belt could be damaged. Call the Dyson helpline. They will listen to the noise and troubleshoot it for you. If it is the brushbar motor they will have a repair dealer look at it. If it is the belt that is damaged, their solution will depend on whether your machine is still under warranty or not.

SOURCE: I had a loose wire in my Oreck XL motor. I took it

Lights are 12 volts.

The motor has taps on it to pull 12 volts rather than 120 volts for the lights, uses the motor as a transformer.

Should be black and white to the motor from the switch, believe the switch breaks the black wire. White wire should be neutral. I can't remember colors for the wires to the lights. Would expect it to be the white wire and then the "tap" wire to be red.

One crazy way to do it, is to hook up wires, leave the light bulbs out, turn on power, and check voltage at the bulb socket with a voltmeter. (This is one of those things they tell you on television to only let a professional do, do not attempt at home.)

Why does it emit a high-pitched squeal (while running)?


This is usually caused by a belt being too tight or the wrong size. It can also be caused by something wrapped around the brush (like loose thread from a rug or yarn, shoestring etc. Try inspecting the brush and belt.

You may have to slip a small screw driver into an open slot of the motor housing to provide a stop for the armature so that you can break the lock nut loose. Becareful to not cause ant damage the armature.

Tear apart all hoses and make sure no clogging, also take apart to expose motor and make sure their is no dust on motor, this will cause symptoms you are describing, another thing check Impeller fan and make sure the fan is running and not blocked if fan is not working then will need to replace Impeller.

Vacuum has become very loud screaching sound


Yes, I would say the crack is causing the screaming sound.

Usually the fan (impeller) is held on with a left-hand nut. To remove it, you have to hold the motor somewhere (sometimes you can just hold the impeller), put a wrench on the shaft nut and turn it clockwise. The impeller should then just pull off (with possibly some wd-40 and a little muscle).

I need help to take my unit apart to remove the impeller. It is broken. The video is too dark and soft spoken to follow disassembly instructions.


on the bottom you will see 2 levers that slide to the side.turn those and the head should come off.there should also be a knob on the top to disengage the belt.once you get the head off you will be at the motor and you will see the impeller.you will have to take the motor housing apart to replace it though.the impeller should be held on with a nut in the middle

Hoover U5750-900 just shuts off


I have a similar bagless model U5757-900 that is shutting off. I disassembled the unit, and what I found is that the motor front bearing had accumulated enough grime so that the bearing locked up. When this happened, the bearing outer shell spun in the plastic housing, causing it to soften, from friction heat. This allowed the motor shaft to become off center from the normal, centered axis of rotation. Once this happened, the rotor inside the motor began to rub against the stator, the fixed part of the motor inside. This loaded down the motor, causing excessive current draw, which caused the overheat switch to activate, shutting down the machine.

In your case, it might not be as bad as in my case.

Remove the dual-cannister dirt cup.

To find out, disassemble the unit lower section: on bottom, remove 4 screws around the rotating brush housing. Remove the brush cover, then remove the brush, then remove the belt. Remove the wide plastic housing behind the brush. Remove the two screws, from the bottom, that retain the upper hood. Remove the hood.

On the back, remove the two screws and hose retainer going from the base to the upright section. This releases the hose from the lower section.

Now press the tilt release, and lay back the upright section. Remove the four screws, two on each side, from the trunnion caps, where the upright section tilts on the lower section. Remove the trunion caps. Remove the upright section from the lower section.

Remove the headlight cover (2 screws).

From the back, remove the single screw retaining the bezel above the headlight area.

Slide the bezel upwards and remove.

Remove the four screws that retain the motor cover clamshell. One is from front, and other 3 from rear.

Open motor clamshell halves to expose motor.

Note orientation/position of the three wires on the motor, and remove those wires. Lift motor out.

To open the motor, gently tap the edges of the impeller housing (aluminum shell) on the edge of the shell, in the little gaps around the shell.

Using a 1/2" socket, remove the nut in the center of the impeller. This is a LEFT HAND NUT. TURN RIGHT TO LOOSEN IT.

Gently wiggle the impeller while pulling until impeller comes off of motor shaft. Use a glove so the impeller doesn't cut your hand.

Remove the large flat washer on the motor shaft. Remove the small sleeve from the motor shaft.

On the brush end of the motor, using a small screwdriver, pry out on the brush holders. Set them aside.

Remove the two screws holding motor together. Seperate the motor front from motor rear. Withdraw the motor rotating part.

Look into the inside of the stator, inspecting for bright, shiny areas where the rotor may be dragging on the stator. If you see these, then the front bearing, in the plastic motor frount, is fried. I don't think Hoover sells this part alone. Also inspect the plastic front bearing retainer to see if there is any melting that has allowed the bearing to become off center.

In any case, if there is scrubbed out places inside the stator, then the motor requires replacement, about $70 for the motor... You might be able to find an entire new vac for less... or, like me, find one on the side of the street where someone has tossed out a unit.

You may luck out and find that the impeller unit is just filled with some trash so air cannot get to the motor for cooling... or you may have a shot motor.

Johnson CL.A U8820-120 motor jammed up in my Bissell carpet power cleaner


I obtained a bearing from McMaster Carr (mcmaster.com) installed it and the carpet cleaner works
once again. I used a double-sealed bearing (part number 5972K221) rather than a double-shielded
bearing (part number 5972K36) which was of the type that failed. The original problem probably
arose from the dirty water tank getting so full that water/detergent is sucked into the motor. I did not
examine the unit to see if an interlock is supposed to prevent this from happening. In retrospect,
I probably should have gone for a stainless bearing (part number 6153K71) which costs $11.56
rather than the $4.26 for the one I selected. The repair was fairly straight-forward but confusing at
times. The motor is under lower front cover (rounded with air vents). This is held on by two
Phillips-head screws set deeply in holes in the back. However, the mounting tabs of the lower
front cover are under the upper front cover. It may be possible to bend outwards the lower part
of the upper cover, but I removed the upper cover. In addition to the two screws already mentioned,
the upper cover is held by two screws passing through the protrusions to which the clean-water
tank snaps are attached. You have to remove these snaps to pull the upper cover apart. After
you get the motor/housing out, you can remove the plastic blower housing with four screws, but there
is a metal blower housing underneath it that has to be pried out. Since the plastic one pries against
tends to break, I ended up repeatedly catching the edge of the metal housing with a screw-driver
blade and then rapping the screwdriver with a hammer. After removing the impeller, the motor can
be pulled free of the blower housing. After removing the brushes, it took a while to realize that
the brass-colored brush housings had to be slid almost all the way out to uncover the two screws
that allow the armature to be removed from the field coils. The bearing is press fit in place, so you
need a puller or some equivalent arrangement to remove the bearing. Not having a press, I used
the impeller nut to press the new bearing into place. It had to be tapped lightly with a hammer
at first. One the nut could grab a thread, it was used to press the bearing into place. Since you
run out of thread before the bearing is fully seated, you need to add some spacers and repeat
the process. I used a stack of washers. When removing he brushes, label their orientation so
that they do not add excessive drag when reassembled. So far, the repaired cleaner has run about
an hour without problems.

Hoover Elite II Model # u4689-910 Impeller replacement


I have had to use a dremmel tool to cut the plastic around the shaft, you can also something sharp and a hammer to break away the remainer of the fan. There are no threads on the fan so to keep truning it may or may not get it off. Just have to watch and not damage the motor shaft and housing.
