Brilliant video - if your AEG or Electrolux vacuum cleaner suddenly seems entirely dead, this is probably the fix unless the cable has failed - and the video shows how to check for that. From the cable the power goes straight to the circuit board which controls all the lights etc, so I decided replacing that was worth a try, and I'm very pleased that for about £30 for the part I've got our AEG UltraOne working again. Without this video I would not have known where to start - it isn't exactly simple and it took me a long time - but I'm so pleased that it worked! Thank you!!!👍
