I have just purchased and installed a Beko GN 162420 X with icemaker. The water dispenser is working with good pressure but the icemaker seem to only produce 12 cubes per day. since installation about a week ago. Is there a setting adjustment to be made or do you think it is a faulty icemeker? The plumbing is the same i had for my previous appliance with Icemaker which was working and producing a full tray within 24 hrs. The manual does not seem to have the answer
