    I'm having the same problem. My B&D SmartBrew DCM500 worked great for years. Suddenly it won't brew. I can see that it's getting power, but the water doesn't filter through and the plate doesn't heat. I tried cleaning it by putting water and vinegar in the reservoir, which is supposed to help get rid of build up, but it doesn't filter through either. Help!

    I just bought this Smartbrew coffe pot 2 weeks ago! The darn thing will not heat up, brew coffee,nothing! The power light is on but nothing happens.

    Walmart offered me a warranty at the checkout counter but I refused because Ive never had a problem with a "new" coffee pot not working in all my life. (I should of known the reason they were offering it to me because they knew I was buying junk!!!) Another $20.00 down the drain I suppose. :'-(

While bikeman's fix was helpful and sure enough got the coffee maker to brew me one last pot of coffee it was also a sure FIRE method for creating a counter top electrical fire!
I followed the solution's directions to the letter and when the pot of coffee was finished brewing the heating element did of course keep heating to the point of bursting into a small electrical fire and melting plastic to my counter top.
I pushed the off button and unplugged the coffee maker and brought it outdoors to cool off before discarding.
While it is a solution it is a VERY DANGEROUS SOLUTION!
I would suggest that anyone who does not have the $20 to replace their broken coffee maker to either buy a replacement over heat sensor or get their brew from a nearby Deli!
Seriously folks this repair is clearly asking for a house fire!
If one were to maybe shut off the maker instantly after a pot was made

I had the same problem. there seems to to be what looks like a diode in one of the wires from the over heat sensor and the heating element. I've done some testing and found this part not letting power through to the element. I cut the part out and connected the wires together with a small crimp conector that I cut the terminal off of. it now works fine.

    A little added note to the repair I posted, to remove the base to make the repair you have to remove the rubber foot pads to reveal three phillips screws and one tamper proof screw. you may have to drill out this screw. I did it by using a 3/8 drill bit not drilling into the screw but drilling out the plastic around it.

Why does coffee come out while pouring in water its a bunn 10 cup coffee maker

The Bunn has a little stopper that closes the water drain port in the reservoir while the lid is open. You can see a little white plastic pin protruding up out of the grate with the lid open. When you close the lid, it pushes on that pin which causes the stopper to lift off the drain port, allowing the water in the reservoir to enter the heating tank.

If water is entering the coffee basket BEFORE the lid is closed, then something is wrong with that little stopper. It may have a chunk of debris on it preventing it from sealing, or it may be deteriorated, torn, disconnected, etc.

Only way to know is to remove the the screws in the grate and pull the top off exposing the reservoir, and the stopper assembly. The little plastic flapper disc should be seated in the reservoir drain port. It should be relatively flat (not wrinkled) and covering the drain port completely. Test it by pouring some water into the reservoir. If it drains out without you activating the stopper, then a repair is needed.

Move the lever up and down and check its operation. The arm must move freely and close when released. There should be no dirt or debris on the sealing surface of the flapper nor on the sealing surface of the drain port. Gently clean with vinegar as necessary. If the seal is damaged, then a replacement is required.

Why did the coffee maker leak bad and now just quit wont gety hot

You seem to be saying the unit "leaked: really badly getting water all over; and now the hot plate will not heat up. Such "leaks" are usually caused when the basket is not pushed in correctly so that the water cutoff switch remains closed when it should be open. (The water cutoff valve is what allows you to remove the pot/carafe in order to pour a quick cup even while the coffee is still drip brewing.) If that cutoff vvalve remains closed for more than a minute or so, or less, water will overlow the basket because with its path out the bottom and into the pot is blocked' and it has not place else to go but over the top of the filter basket holder. Now, when such an overlfow (not leak) happens, there is the hot plate right below into which the overflow flows down. As long at it remains wet it will be short circuited and not heat up. So let stand and/or blow or hairdryer heat to remove all water (be sure to unplug coffee maker to to that). Now, once everything including the hot plate are dry, the coffee maker will either work fine, or will need to be replaced.

When machine is turned on from the off position it does not go into rinse mode message comes up to hot please wait and yet the machine has been turned off for at least 20hrs

the power on sequence for the XP9000 is
1) Internal diagnostic
2) if no cold water, display notice and wait for water level in cold water tank
2) if water heating block is not hot, display notice and wait for block temperature
3) display "Rinse Press Hot Water" notice and wait for button press
4) rinse
5) display "Select Beverage" and wait for button press, ground coffee flap, or other input switch state change.etc...

in short... its doing what its supposed to.

Please consider reading the manual supplied wih your XP9000 or downloading the manual if you don't have it.

The water in my cuisinart coffe maker DTC 975 doesn't advance, I added water/vinegar mixture and not works yet, can you help me. Thanks.

I provided the following answer for another question about the coffee maker, if you or someone else feels confident in taking the coffee maker apart, this procedure may solve your problem. The water will not move until it is heated. It can be heated if the thermo fuse/s are blown.

If the coffee maker will not pump water, and will not get hot, chances are either one or two of the 240 degree C thermo fuses under the bottom plate are blown or the heating element has gone bad. Unplugged, using a T10 Torx driver, I removed the four screws from the bottom plate. I pulled one of the rubber hoses loose, not from the metal element but from the plastic fitting. I forced water through with a garden hose to remove any beans or other debris in the hose. I put the hose back. I checked the two thermo fuses, both were open, the unit probably ran without water or the filter was plugged. The thermo fuses are 240 degrees C as I mentioned. Radio Shack sells 228 C fuses for $1.79 each, probably close enough. Clip the old fuses out, close to the fuse as possible. Solder in the new fuses, while holding the wire close to the fuse with needle nose pliers as a heat sink as to not overheat the fuse and blow it. Once the fuse cools, solder the other side, again holding the wire next to the fuse. Once both are soldered in, check with an ohmmeter to be sure you did not overheat the fuses. If ok, secure your wiring, make sure nothing is touching, put the bottom back in, clean up as necessary, put water back in, beans as necessary and try it. Worked for me. Most likely cause over the years beans falling into the water and clogging the filter. I'd recommend at least once a year, remove the filter and hose out the water reservoir. Replace filter if necessary. Once the unit runs dry, the elements overheat and blow the fuses. When making coffee, it will use all the water and shut itself off, "normally."

Please understand that you will make this repair with the unit unplugged. If you reassemble the unit incorrectly you could create a shock hazard, make sure none of the bare wires touch anything they shouldn't.

Coffe maker turns on and drips a little into the filter then stops. The coffee grounds are still dry and it doesnt make coffee. The plate is hot. The coffees not.

First check that the thermo switch is not opening at to low a temperature. Can you measure the hot plate temperature? It should be over 180 degrees. If not then it the thermo. I would replace the Thermo switch, These are not soldered in because of the heat application. You must use mechanical connections, such as crimp splicing.

The other option is that the water can't flow into the heating element Or from the element. There is a one way value in the feed path that needs to be checked that it is functioning. You can test it with straws on units that do not have a removable water tank. locate the water drain in the tank and take the straw and place it at that drain and blow hard. You should hear air flow through the unit and out the drip tank. You need a far amount of seal at the bottom for this to work, I built a ridged tube with a cup on the bottom. This will not work if there is a bar grid were the water is pored.

Good luck.

Coffee maker water does not heat

unless you have a real expensive coffee maker, it is cheaper to just replace it at this point. chances are the heating element has burned in two.

No hot water for coffee? model twood12619-1900w.

It sounds like your heating element or it could just be your heating plate.
I found this information that might also help you out. I found it
Basic maintenance can minimize repairs. Periodically brew a batch of water without the grounds, adding a small amount of vinegar to the water to neutralize accumulated acids. In addition, if you live in an area that has hard tap water, only use distilled or filtered water in your coffee maker. Not only will it last longer, the coffee will also taste better
