Inside ,the dust collection container, there at the far end is a white cone shape (another filter). I think you may find this covered in lint etc and if you reach in with your hand you can just pull the stuff off. Happened to me around the two month mark and I THINK, so far, so good. My machine is now not switching off and flashing lights at me and the suction is back to fabulous. Found this information on another obsure website. You would think electrolux would mention it in their "Troubleshooting Guide" GOOD LUCK

One long beep and two short beeps usually means a video problem. If you have an add-on video card, try replacing it with a new one. If you are using an on-board video, go into the bios and turn it off. then shut down & install an add-on card.

In between the filters there's an access panel that can be removed - there may be a blockage there. You should also check your hose for a blockage.

Otherwise you may need to take it to your local Electrolux Service Center. There may be a problem with the pressure board. The machines have a 2 year warranty, not sure what it'd be in your neck of the woods.
