The huge water tank of the K-fee GRANDE capsule machine holds an enormous 3.5 liters. This spare part is original from the manufacturer. It has a special holder for the GRANDE water filter. The lid of the water tank is also shown in the article photo. PLEASE NOTE THAT THIS LID IS NOT INCLUDED IN THE DELIVERY. You can also buy one individually. For optimal care of the water tank (and the entire capsule machine), we recommend regular decalcification or the use of the water filter - you will find cleaning fluids and filters in the shop.
