Hi, After seeing a video in youtube and here the link below JBL's 'CristalProfi' External Filter - YouTube I cleaned the filter yesterday but in the link showing we just remove the sides sponge on the top and replace them with new one but I saw the full filter was dirty so I did not replace anything but I cleaned all the sponges and put the ceramic carbon under the tap and I cleaned all the pipes and I saw too much dirts are coming out. I started my cleaning because I saw the water which is coming out of the filter is little not like before and it was little because of the dirts. Also in the link they are showing we press that big button on the filter smoothly and it works but unfortunately we should press strongly. Any idea if I am doing anything wrong. Thanks a lot.
