Question about DeLonghi Caffe Nabucco BCO70 Espresso/Coffee Maker
Why does coffee maker leak from bottom
I have had a few of these machines leak.
I pulled off the bottom and found Mr Coffee is using low quality tubing that melts or leaks where it attaches to the heater element that boils the water. I replaced the tubes with higher quality silicone tubing that I bought directly out of China on Ebay and the problem was solved.

Check the water tray first, it is more likely a leak from one of the internal hoses, the machine must be probably taken apart and inspected to fix this.

There is a hole that goes though the bottom of the water chamber side.
The unit will not leak when there is water in the water chamber. The only reason for water to come out the hole is condensation from making the water. There are no hoses in the water chamber area.

SOURCE: Unit leaks out of the bottom
Mine just developed the same problem. Me being an engineer, I decided to take it apart and found the problem. There is an aluminum tube shaped like a "C" with a heating element inside of it. Water flows through this metal tube, is heated, and then pushed via steam pressure. There is a metal brace that holds this "C" piece securely to the bottom of the machine. This brace is sharp and overtightened, which caused a small hole to form in the metal, causing the leak (in my machine of course). I am currently researching how to patch aluminum so I can hopefully fix it.

If it leaks DURING brewing, you may have to decalcify it (aka, run through a cycle of 4 cups vinegar, fill to the top with water, 2-3 times and see if it helps).
If it leaks before you even start brewing a pot of coffee, something is broken on the inside of the coffee maker, and I would recommend contacting Waring--they may be able to get you a replacement coffee maker (and if you're under warranty, usually a replacement would be free!).
Their phone number (according to their website, www.waringproducts.com ) is 1-800-4WARING (1-800-492-7464)
Good luck! :)

The tool is a special tool that is either meant to be vandal or idiot proof. Being one of the aforementioned I bought a set of these special tools at Sears. The first problem is Cuisinart recesses the hole so much that my tool can not remove the screw. I tried widening the hole using a drill bit but it cracked and broke.
As for using a hose from a hardware store, I have been there and done that. The hose attatched to the warmer side melted and leaked everywhere.

Please get the model and the date code from the bottom of the machine and contact customer serivce. Depending on the date code, there might be a seal kit available or the machine can be replaced at no cost if 3 years old or less. If it is over 3 years old and the seal kit isn't available, the machine will be replaced at a reduced price.
