Is the flex all right? Check it with a voltmeter or a continuity meter (available for a small sum in your local hardware or electrical shop).

get new bag filter , empty dirt out to garbage bag , clean hose .

Should not be that loud. Check all the filters and see if they are ok. Check to see what the suction level is. This is kind of subjective. IT might have a bad bearing in the motor.

You need to have the vacuum cleaned out. If you are good with tools, just remove the motor and fans assembly, take the fans off and wash them. Brush ALL dirt out of the housing and reassemble. Your Electrolux dealer can do this but it isn't cheap. I used to be the service manager for my area. Since it isn't under warranty, you can have ANY reliable vacuum cleaner shop give a good cleanout. NEVER put anything into the cleaner to make it smell good. Electrolux cleaners get their power by having a straight through suction. The air goes through the motor. Adding smelly things can crystallize onto the motor and burn it out.

Look to see if the main air filter is clean (some can be washed and others have to be replaced) it will if blocked up trip a thermal cutoff to protect the motor in the unit.

We had a vacuum cleaner that did that and it was the signal to say the bag was full. So to test this remove the bag and see if problem goes. If it does- replace the bag.

So all that is left is a blocked filter, ie paper like the ones in a car, remove- wash bash out the dust etc- I use compressed air to blow them oput backwards. If it is bagless there has to be a filter somewhere otherwise everything comes straight out.
I would also be looking at hose obstruction and leaks in the body of the system - assuming it still sucks well enough. I often remove the hose and drop a heavy steel rod or the like down to shake out the hose. I have a lot of this with saw dust on the shed cleaner.
If it were mine I would then pull it apart to look for bockages or bits caught in the fans. But do not do this if you are not confident of reconstruction safely or if there is a warranty available.

take it back for a refund and buy another make I have had one also my daughter they are hopeless, they work for 7 minutes then cut out. Not fit for purpose, Electrolux are not interested in solving their problems
