Zyliss Cheese grater Classik

Once only I had problems with the larger cheese graters from Zyliss -
after a short time each broke the lock of the grater cylinder -
I had bought the "Classik" 2 years ago.
Actually, I was happy with the result - can easily be
quarrels, the Parmesan is grated tidy.
Unfortunately, this was now rubbing up the ghost: the weak
point is the holder of the boom, here the lead broke
the Niro-axis (plastic) - this disappeared into the nirvana of a
Dishwasher, the grater is no longer usable.
Supposedly 5-year warranty from the manufacturer?

Addendum: After the German importer / customer service was found
there was actually a warranty replacement, ie a new grater !!
