Feb 24, 2013· Re: Elektra Nino Yiasou KK. Thank you for your response. Is there a video on how to dismantle the grinder,and take off the upper burr? I ask,because I am afraid to "touch" the grinder. If I can not do this job,I call for the Elektra service in Athens. Anyway,I write here again, the cause of the problem. Regards, Theodore.
