Heller Electronic Ice Maker HIM10S

Foolish design - giving it to the op shop – I have a white Heller HIM10 ice making machine which was gifted to me 3 or 4 years ago. It has a plug at the bottom of the water holder which is meant to allow you to empty the machine by sliding it out from the benchtop and holding a bowl underneath the drain hole, or just placing the edge of the machine over the sink. However, the little plastic tab on the plug is so tiny that it's impossible to get a good enough grip on it to pull the plug out! Therefore, to empty it, I have to lug the machine over to the sink and turn it upside down to let the water run out. As the manufacturer's instructions include the proviso that it's not meant to be turned upside down, this is scarcely satisfactory. I have emailed Heller a few times but received no reply. I'll be ensuring nothing made by Heller enters my home again.
