I have the same coffee maker, but with a little different problem. The heating coil in the base has corroded through from galvanic reaction due to a failed anode, so I tried to get internal parts from Cuisinart, but they refuse to offer internal parts support. They would rather try to sell you another coffee maker. . . at least that's what they did to me.
My only suggestion to you, might be to locate a used one somewhere and cannibalize the parts you need.
Cuisinart was NO help whatsoever, sorry to say.
