The highest d# was not sounding on the push. I called Petosa and they gave me a solution to fix it without opening up the accordion. They instructed me to choose the master switch (in my case 4 reeds) and then play the d# and the adjacent reeds ( c#, d, d#, e, f ) all simultaneously with substantial air going through the bellows and then make forceful bellow direction changes. This blew out what was ever causing the reed to not sound, problem solved.
