Most commonly, this means that power cord on the bottom of the machine is loose. Babycook Solo & Duo are designed with a removable cord for easy storage, but the cord needs to be pushed in all the way in order for the machine to function. Simply turn over your Babycook, remove the cord and then push it back in as far as it will go. If this does not work, please call customer support at 855-602-3222 or open a ticket on this website.
