I need a replacement Carafe for Back to Basic CC5500 coffee maker
If the leak is in the seal between the metal center which sits over the warmer and the plastic surrounding it, disassemble it by removing the screws holding the metal to the plastic. Remove the metal center and the silicone gasket. carefully clean the sealing surfaces of the coffee residue on the metal and the plastic and both sides of the gasket, use detergent in hot water, scrub it if necessary and also use some ammonia in the wash water if needed. Thoroughly rinse the cleaned parts with clean fresh water and let it dry. When dry wipe the surfaces with a sturdy paper towel wet with rubbing alcohol to remove any residue from the water.
Glue/seal it together with a silicone caulk which says somewhere on the tube that it is OK for aquariums or one that DOES NOT have any biocide or anti-fungus or anti-mildew additives, they are usually not good for food preparation utensils like your coffee carafe.
To seal it, remember the caulk is very sticky and will make a real mess if you get it where it is not supposed to go, so be very careful and use the minimal amount to leave narrow bead of caulk on both sealing surfaces on the plastic and the metal pieces. It is easiest if both sealing surfaces are placed on a sheet or two of newspaper on a conveniently situated counter- top or work bench. When you are satisfied that there is a narrow bead of caulk ALL the way around the circumference of the sealing surfaces, VERY carefully align the gasket's straight length (about an inch) with the mating surface on the plastic part which is attached to the glass. Gently press the gasket down to the caulk after double checking to make sure it is aligned with the shape of the sealing groove. Now you are ready to place the metal piece on top of the seal, again making sure the straight part of the seal is aligned with the seal you just placed on the glass/plastic part of the carafe and the holes on the metal base align with the holes in the plastic/glass part too. When all is aligned, push the metal piece toward the plastic/glass carafe part until some caulk oozes out and the pieces are close enough to start the screws. Be very careful when starting the screws to make sure they are in the same screw threads, since plastic is MUCH softer that the steel screws, they can cut new threads and then may pull out or not be able to be tightened. to make sure the screws are in the original threads, place the screw in the hole, turn it BACKWARDS up to one full turn, until you hear it click into the original screw thread or feel it drop into the thread. then you can screw it in only a couple of turns. To make sure not to warp the base or damage the plastic bosses that the screws are going into, after starting all the screws, screw them in one by one a few turns at a time going around the circumference of the metal by opposites (if six screws, screw in this order, 1 - 4- 2 - 5 - 3 - 6, then back to 1 and start all over) until the plate is screwed down and the caulk as oozed out all around and the screws are fairly tight. Again the plastic is weak, so you need to screw the screws in firmly, but not too tight. If you are using a jewelers screw driver, it is hard to over tighten the screws, because the screwdriver is so small. This was the hard part, now let the carafe seal cure for 2-3 days, longer if it is very low humidity, since the silicone needs moisture to cure. When cured, the excess silicone caulk can be trimmed off with a sharp knife or single edged razor blade or a utility knife with a sharp blade and the pot should be ready to go. to leach and flavor from the sealant, run a few pots of water through the beast...
If your "sneak a cup" valve is leaking, like ours, try this, take a utility knife and cut the screen out, clean the surface of the tube between the inside of the pot and the valve as best you can. Go through the same cleaning procedure as for the gasket. You will probably have to remove the valve mechanism to do this, note that the third screw holding this valve in is under the handle, which must be gently pried apart to access it. when all is clean, including the valve gasket and the plastic valve mechanism, put it back together. Then fill the space between the valve gasket and the inside of the carafe, where the screen was with silicone caulk, until the caulk completely fills the hole to overflowing. After it cures, in a few days, trim it as best you can flush with the bottom of the carafe. Then run a few pots of water through before brewing any coffee. Hopefully, the leaks are sealed and you have coffee pot that doesn't dribble all over the counter...Have fun!
