Canister vac - the motor on the cleaning head cuts out while vacuuming. does it as you draw back the head while cleaning , goes off momentarily and ten when pushed forward engages the motor again. this is the motor in the head that turns the brush. the vacuum motor int base continues to run uninterrupted.

You either have a broken power cable going to the head or your canister isn't supplying power to the head, or the motor for the head it bad.

You should remove the filter that is inside the vac. This should allow for the vac to **** up the water. But just in case that doesn't do it, here is a link to a site that may contain a free download of your manual:

Just look up your type of vac and click on it.

Good Luck!

If the suction motor doesn't come on but the brush motor does, you have a bad vac motor. If neither motor runs, it's probably a cord problem. Most parts for these are not available anymore.

Check to be certain the thermo lite is on and not the bag full indicator. The thermo detector is very reliable, but the bag fill valve often fails. If it is the thermo, check your hose and wand for blockage by dropping a coin through them,before opening the vac itself.Otherwise you may have a bad set of motor bearings causing the motor to overheat due to its age.
The 2100 and all its canister cousins made since 1982 seem to be prone to failure of the dial valve on top cracking internally. The causes the bag full indicator to come on and the vac to shut down.
To open the vac you will need to slide the locking keys and bumpers forward with the bag door open. Do this with a set of pliers. Once done the vac will open from front to back like a **** shell. Be careful to look at the underside hinge are of the bag door before separating and mark and locate the wiring harness . This vac only goes back together one way, perfectly assembled it pops together with ease. If any piece is out of line it`s like a RUBIKS Cube. Take your time . OEM parts are only available through an AERUS Elctrolux dealer or repair shop

It sounds like you have a blockage somewhere and the air is not passing over the motor to keep it cool. There is usually a thermostat mounted either on or near the motor. The blockage can be anywhere from the elbow ( the swivel part of your carpet sweeper if you have a canister vac) up thru the hose.If you have a canister vac, use a broom handle to push through the hose to clear the blockage. DO NOT ! use a coat hanger or anything that will cut or tare the hose. There are electrical wires in it that have 120 volts and causes quite a shock !
.
If you have an upright vac, start with the duct hose that comes from the part with the brush up to the hose and on to the main canister of the vac
If this does not work, take your vac to a reputable vac shop for repair. Hope this helps,

hi from uk your problem with vac may be the gauze filter on the inside of the compartment that has bag this filter there to allow air from the micro pores of the bag to expel to the exterior of vac (room) whilst preventing dust from expelling too ? normally another symptom of this is the vac cover sometimes flips up ? however if air cannot expel from compartment it will cause overheat of motor resulting in auto cut off but will reset when cooled SO check the filter gauze and renew or wash clean? hope you understand above and hope this helps ?

If your talking the motor on the beater bar, then chances are either when the beater bar was attached to the hose near where you hold it, it did not lock, and the connection is intermittent, or the cord has an internal break.

likely after all these years that the motor is starting to go bad and draw more amps thasn it should. a new motor at a vac dealer is your best bet. it was likely made by panasonic, so a new panasonic is your best bet, and less $$$than the kenmore for the same vacuum. sears parts are extremely expensive

If it sounds like the vacuum motor is running then you have a clog. Clean out any hoses where a clog may be. If the vacuum motor does not sound like it is running then you will need to take it to a vacuum repair shop. Or you need to make sure the canister is attached correctly. If the canister is not fitting correctly then you will lose suction. Hope this helps, post back.

IT SOUND LIKE THE MOTOR WENT BAD OR IN SIDE THE PANLE A WIRE CAME LOSE
