No power to vacuum motor. Switch need to replace.

Remove the wand to gain access to the screws you will need to remove and the tabs to release the cover holding the switch. Pull the cover off to remove and replace the switch.

You say that you have checked the belt, so I assume that you ensured that the belt is engaged properly and is not slipping. When you press the switch on and then off, do you hear the belt drive motor turning? If not, then you either have a defective drive motor or a defective switch. Testing the switch will give you the answer. To do that, first unplug the vacuum from the wall outlet and then gain access to the switch connections be removing any parts that prevent such access. Using an inexpensive digital multimeter set to read ohms, touch the two probes together and you will see the meter reads 000.0 and that is the same thing you should see if touching the probes to the switch connections with the switch in the "ON" position. In the "OFF" position, the meter should show something other than zeros, or show no reading at all. If your readings are as they should be, the switch is good and you then need to ensure that the wires connected between the switch and the belt drive motor are in fact connected securely and are not loose. If the connections are good then next you need to determine if you are actually getting power to the switch, and if you are then the belt drive motor is the suspect. If you don't know how to test for power at the switch using the meter or a test light then you should ask someone to assist you who does have that knowledge in order to avoid the possibility of electrical shock. If there is no power to the switch, there is obviously a bad connection between the switch and the power cord which feeds it, so you would need to trace those connections and determine the cause.

heres a video that will show you

Remove the dust compartment door to gain access to the cover over the wiring and switch compartment. Remove three screws to gain access to be able to remove the old power cord and slide it through the hole in the back of the vacuum. Put new cord through the hole and wire back up as it was before.

Gain access to the electrical connection with voltmeter set to 110 v ac check for voltage on both sides of switch. If voltage is present on outlet side follow output wire to start relay ck for power on out put side of relay. if power follow output wire to motor if voltage is present replace motor ! Be careful where you touch when probing contacts !

Vacuum cleaner repair manuals seem rare and difficult to obtain. The instruction booklet does not contain dismantling and repair details because to do so would make them responsible for encouraging incompetent people to electrocute themselves.

Vacuum cleaners are generally fairly intuitive to dismantle and the circuits fairly simple. The switches are sometimes found to be faulty but it would be wise to assume nothing. I once scrapped a cleaner assuming the motor was defective in the absence of other faults but when I had already removed everything but the motor, when I finally lifted out the motor I found a (faulty) bimetal thermal breaker...

Open in the power cord to them

well, i post an answer in the wrong field, and i can't find it, so i will type one more time.
slide two vinyl side pieces off, and remove top halves. remove two screws from the switch, and remove it from top halve. between switch and outside button is a plastic rocker, which is broken. you will find two broken pieces, one spring for the rocker piece, and one small plastic rod, which goes inside of the spring for support. i do not know if part is available, but you can for quick fix like me, turn the switch on by the hand, assemble unit, and plug in, and plug out from the wall. whay? i dont have electrolux store close by.

Panasonic MC-E 450UK upright vacuum cleaner.
Just had this problem myself...........easy to get at it when you know how.
Panasonic UK wouldn't help me so I spent some time working it out..........here it is.
Remove the hose from its mounting storage at the rear (called hose clip) where the main body of the vacuum cleaner meets the base of the handle assembly. Remove the screw at the rear of the handle assembly which is behind where the hose 'was' situated and is located inside the deep recess.
Using the soft part of your clenched hand as a hammer, knock the base of the handle assembly at the front and it will slide backwards off the main body of the vacuum cleaner. Don't be scared, give it a thump and keep moving it backwards with a few more knocks.
Next remove the two screws at the front which hold the mains cable and on/off switch cover in place.
Finally looking from the rear once more, lift the plastic 'lug' at the top of the cover and which is part of the cover. This will now allow you to release the cover and pull it forward.
There you go! Told you it was easy!
Watch out for the funny little spring at the front behind the cover in the tiny plastic tube where it connects to the small rubber tubing as it could possibly try to escape.
You now have complete access in order to cut the intermittent part of the cable out and remove it from the 'choc' block.
Happy fixing!!
Jack.
