Model number CVA 4066
Appliance category Coffee Machine

The Miele CVA 4066 is a built-in coffee system that can run from a plumbed water connection or from a removable tank. Its overall front width is 23 7/16 inches, and it needs a 120 V, 15 A supply on an accessible NEMA 5-15 outlet. The water connection uses a 1/4-inch copper compression fitting. Personal settings can be saved for up to nine users, and the main dispenser moves up or down to suit the cup. For Miami, New York, Houston, Los Angeles and San Diego metro areas, describe what the drip tray or the cup shows, then give the full label number and any message.

The combination of a plumbed connection and a removable tank gives the owner a choice of water supply, which is uncommon in a built-in coffee system. Nine personal profiles keep each person's strength and size settings separate. A separate chute for ground coffee lets the machine switch between beans and pre-ground without mixing them. Day to day, the owner can pick the water option that suits the kitchen.

Service notes for the CVA 4066

When coffee leaks into the drip tray, a technician checks the drain route and the tray sensor, since an overflow often starts with a blocked outlet. Weak coffee or no brew points to the grinder setting, the water flow path and the brew unit, which should be rinsed by hand rather than run in a dishwasher. A descale or error message that will not clear is tested against the descale cycle and the water filter. Owners can safely note whether the water came from the tank or the plumbed line, which profile was in use, and the message on the screen. Empty the drip tray before testing and keep the brew unit out of the dishwasher.
