Bosch Flexxo Serie 4 BCH3ALL21 Cordless handstick vacuum cleaner - Repair

[@louiscapelle3090]

Thank you. My problem is a little bit different: batteries have to be replaced because they don't hold the charge very long, but thanks to your precise video I found the last (hidden) screws and all is open without breaking something. I have to order the 3,7V cells but I will be OK.

Большое спасибо за видео. Мой пылесос имел ту же проблему. Смог разобрать пылесос баз поломки крышек и спаять провода мотора. Сейчас пылесос работает как новый.👍👍👍

In my case, the motor bearings on my vacuum lost lubrication. This caused a gradual decrease in motor speed resulting in increased load that shortened run time before recharge. This remained undetected until the noise became unbearable.

Did you solve the issue?

[@DaveVelo1]

@@kasperlangble8350 I thought so at first but the increased load over time took it's toll on the batteries. Now the pack will need replacement.

[@kasperlangble8350]

@@DaveVelo1 How and where did you lubricate?

Nice. I just open main to clean it and now it doesn't work anymore damn.. I put all the switches as they were but nothing tho. One thing I did I put a bit of wd40 oil where the fan is so it cleaned a bit. You think that messed up with the circuits?

[@XoNGameDroid]

Hello, It should be checked if there is voltage at the cables entering the motor you should have around 21v (when the switch is ON). If you have no voltage, you should check the wiring between the battery-switch-motor, one may have been interrupted when you opened the vacuum cleaner.

@@XoNGameDroid aww man even tho it sounds so simple I have no idea how to do it even that I own one of those measure machine I never use it or know how to use it lol. If you ever will do a video hie to do all you told me would be greatly appreciated!

[@Shaylesety]

@@XoNGameDroid I have power I can tell you that. But not the way I wanted to.. I switched 2 cables around and the fan is starting but the switch for on off does nothing. Do you where I cand find how cables were originally on the logic board or you have any fotos? Give me an e-mail please and if you could help me out with this I will pay for your time tho

After seeing this very useful and informative video, I have decided to throw the Bosch and buy a Shark, which has removeable battery packs.
