Peggy, a number of things could be wrong, so you should start with the simplest things (your statement that the "device won't work" implies no heating at all, which implies an "Open Circuit"):
1) Is the outlet working properly? Check it by plugging something else into that outlet (a lamp, for example) to test the outlet. If the outlet checks out OK, then....
2) Next, inspect and check the cord - if you don't know how to check the electric cord for continuity with an electrical tester, then simply replace the cord with a new one. If the new cord doesn't fix the problem, then......
3) The next steps would require disassembly of the unit to see why and where there is an "open circuit" somewhere inside the unit. It does not sound like you could tackle the disassembly and repair of the unit - some electrical knowledge and testing capability is required.
That is a very nice coffeemaker and is worth fixing. You have not provided much in the way of symptoms; just that the coffeemaker does not work. Does the urn heat up at all? Does the cord get warm?
