I bought the replacement nozzle in a Braun Service Center, because I still need other spare parts.
Having previously seen here on amazon, I naturally requires the "new model of 2010".
But the staff told me that there does not exist something like that!
Nothing has changed at the nozzles!
When I asked him about it, that the rotation function is often so fast is broken, he gave me the following advice:
One should with a needle a small metal screen to remove the bottom of the nozzle.
That is the cause of the problem.
Enough already evident the dust from a few weeks to shut the screen so far that the rotation function does not work anymore.
Through the dust, the water pressure and nothing works anymore decreases.
He also said that the lime has thus emulate anything, because you can not descale the irrigator, as the installed lines have Antikalkbeschichtung that can be attacked by descaler.
That would have to stand at the current devices in the manual.
I have removed the small screen so more than half a year ago and the nozzle still work absolutely perfectly.
Sometimes it depends briefly when switching to the rotation but a small blow with the finger against the nozzle head and it turns back wonderful.
By the way, we have here in Munich quite hard water with 14.4 degrees dH (2.58 mmol / l).
At the lime it is so in fact obviously not!
So I am, thanks to the above tip, completely satisfied with these nozzles!
I hope the tip will help some here on!
