Philips Sonicare repair: Loud rattling noise, Head loose

Описание: I thought I'll make a 'short' tutorial of fixing the Philips Sonicare .. well it got a bit longer, but I hope I can help anyone that sturggles to open or repair it :)

The Model seen in the Video is the "Philips Sonicare ProtectiveClean 5100" - Model number HX684A.

The common, well known problems are adressed:
(1) The Toothbrush gets quite loud, with a rattling noise and the vibration is poor or not that soft as you would expect a "sonic"-toothbrush to be.
(2) The brush head becomes loose and is wobbly, in my case it felt like something was broken inside - luckily, it's just a screw that needs to be tightened.
