Re: [APD] Eheim rattle


I have a twelve year old 2213...

When you remove the top you can open a rotating door...
Carefully because there is a rubber inside !

You see then the rotor and a ceramic (hard but breaky) axis.
After some time the rotor wears the axis making it glad at two places :
making it too thin and allowing noise...

Solution 1 is to put some oil
Solution 2 is to extract the axis from the other rubber (you don't see it)
carefully not to break it and inverse it in such a way the rotor touches
a thicker place (adding oil now shall be a good idea : ONE toothpick drop).

Then you put all in place and close again...


In Belgium new axes are quite cheap.  At the end the rotor can become worn out
 which is more expensive to replace.  But if you change the filter every 20 years
it is OK to change it after 10 years ;-)
