I own a Black & Decker (Applica) 12-cup Smartbrew Coffee Maker DCM2000 (see link). Mine started leaking water out of the bottom when brewing. I was able to remove the non-security screws and pry open the plastic bottom to see what the problem was.
Smart Brew 12 Cup Coffee Maker
In my case, the silicone hose running between the water reservoir and the heater/pump had become brittle over time and split where it met a metal tube.
There are two of these silicone tubes in the
Smart Brew 12 Cup Coffee Maker DCM2000. In the third photo below, you can see the bottom/inside of the coffee maker with the faulty tube missing.
Replacing a silicone tube - easy. Getting the bottom completely open... not so much.
In order to get the bottom completely off, I used a bolt cutter on the security screw.
I was able to buy a length of the following hose (from ebay):
Silicone Tubing - High Temperature rated AND Food Grade
3/8" Inside diameter x 1/2" outer diameter
It's important to get the inside diameter correct, or the hose will not grip tight enough to stay in place/form a seal. I measured the original to get the appropriate I.D.
The hose must also 100% silicone, food grade, and rated for high temperatures. Beer stores and brewing supply companies typically carry this kind of hose. I got mine from ebay.
I cut the silicone hose to the proper length with a utility knife and slid it over the two receptacle ends - one end of the metal "U" & the round plastic socket leading into the water reservoir.
I put the bottom back on, attaching the regular Phillips screws.
I've had leak-free operation ever since.
The hose cost me a bit more than expected, because I couldn't get it locally and shipping costs in/to Canada are a complete rip-off - but it was still a fraction of the cost of a brand new coffee maker.
