Look on YouTube videos on "harmonica cleaning".

Look on YouTube for videos on "harmonica cleaning".

There are good videos explaining how to clean harmonicas on YouTube.

Search for "harmonica cleaning"

Here is what Hohner says:http://www.hohnerusa.com/index.php?1615 This site is for chromatic harmonicas but the advice applies to all models:http://www.angelfire.com/music/HarpOn/maintclean.html

I can't tell where you are but I hope this link helps:http://www.harmonicalinks.com/repairs.html

These harminicas are warranteed and rarely have problems. Either return it to the place of purchase for an exchange or contact Hohner directly. My experience with this company is that they are eager to make things right.

Probably just needs cleaning. Search google for cleaning instructions. Dirt or deposits on the reeds increases the mass and will cause them to go flat in pitch.

You might find the info you need here:http://www.harmonicalessons.com/repairs_chart.html It sounds to me as if you have some stuck reeds.

You can take it apart by removing the two screws, see if any of the reels seem blocked or obstructed by dirt, bits of dust, oxydation (greenish crystalline stuff) or similar, try to remove the stuff that seems to obstruct the reel with a medium hardness paintbrush (you might want to use some alcohol), but be very careful not to permanently bend or otherwise damage the reels, it will ruin the sound of the harmonica.
