Brews good hot coffee but warming plate has stopped heating! Are replacement elements readily available or could it be a fuse...??

The DCC-1200 has only one element, that both heats the water for brewing and keeps the carafe warm. If you're brewing coffee then the element is fine and the suspect part is the Thermistor. Another forum suggested this was a Vishnay NTCLG100E22245B, available from DigiKey (their part # BC2467), connected to the control board with thin yellow wires. The same forum suggested that this thermistor should test at 220K ohms at room temperature, dropping to 20K at about 220F.

Temperature is low even when machine is set high

warranty? Owner's manual? troubleshooting section? Last of all, MFG customer service is usually helpful if you're nice about it.

I have a 1993 chevy suburban and just replaced the thermostat, because addmissions wants the surburan to run no higher than 160f . Well the thermostat works but dosen't kick in untill it reaches 2

you will be hard pressed to get a thermostat that opens at160F as that is 71 C and most thermostats have an opening temp of 80 C (175 F) to 85 c which is 185F
at a temp of 220F which is 104.4 C your engine is near boiling
it indicates that the thermostat has been incorrectly fitted in that the bulb or major part is not in the head or block water but in the hose section
go to the dealer spares and see what the temp range is on a new thermostat but I doubt that the manufacturer will get a special thermostat as they use generic items from thermostat manufacturers put in expensive packaging

Our office has a Gevalia Deluxe coffeemaker. It

Most likely the cycle thermostat that turns off the heating element has failed. It is supposed to reset after the it senses the water temp below 130 deg. If it did not reset or has failed it will not turn on the heating element but the clock will work fine.

By the time you ship the unit to a repair center with parts and labor and get it returned to you the cost would be as much as a new unit.

Thanks for using FixYa.

When i make coffee sometimes the water that comes out is cold or luke warm

The brewer has not had enough time to reach its operating temp (usually 7 mins after a brew cycle). If that is not hte case then the machine needs to be descaled.

Bloomfield 3-pot coffee maker won't brew

These macines have an internal water heater that should be clened periodicly (monthly per manufacturers instructions but I do it quarterly/semianually/when it gets noisy :) ). The machine will have to be disasembled to do this since the tank will have to be flushed when you do this to get the chemicals out of it (vs running a pot of vinegar through your Mr. Coffee machine at home), Depending on how much scale has built up in the tank this could take several cleaninings. Scale deposits can over time impair/damage the heater or thermostat but replacement parts are cheaper than a new machine and the machine will outlast and outperform a standard coffee maker. BTW, my 8572 3 burner was built in 1972, I bought it at a flee market for $25 10 years ago put $100 in parts to get the push to brew and hot water on tap working again and it made two great pots of coffee this morning.

Bad tasting coffee

Hello. Usually bad taste is one of 3 things, water quality, coffee quality is changed, or brew temp is different. Try removing all the water, by tilting the unit over the sink, unplug please, so the end where the funnel would go is draining the water into the sink, go slowly. Once all the water is removed, refill it with fresh water until it comes out the spray head/funnel area again, plug back in, heat and test. Now there could still be residue in the tank, and it may require doing this a couple of times to clear fully. Try another coffee, may have just had a bad can/bag/etc..
Last, take the temp of the water coming out of the funnel, should be about 180 deg. F, if not it could be too cool, and needs a thermostat or element. If you need a service provider, go to and locate a service near you.

Hope that helps, and thank you.

The warming plate is controlled by the same thermal switch that cycles while brewing and they are mechanically in contact; it switches at about 150 degrees C.  Most later coffee makers have a time limitation as well and if they are so designed, will turn off completely after 30 minutes to 2 hours after the brewing is finished to reduce the chance of the machine failing. If you insist on having one that doesn't behave this way, you can buy a cheap one from a 'dollar store,' they don't have that feature and will continue to cycle until turned off.  Your B&D isn't malfunctioning, that is how it was designed.

My bunn coffee maker CWTF-15 21604-0001

It sound like you are either missing the sprayhead or the temperature isn't hot enough. Check first to see if the sprayhead is there. It fits under the brew basket and looks like a little shower head - it's round and has usually five or six little holes in it. If it is missing your coffee will be weak due to the water not being spread across all of the grounds evenly.
The other thing to check is the temperature. Depending upon where you live the water should be between 185F - 200F. If the water is below that temperature the coffee may look like tea.

Why even mess around with a leaky coffee pot? Just buy a new one theres a ton of garage sales if a new one is not in your budget. I noticed the same thing a little leak and as soon as it would start to brew....I also thought I was just spilling water around the heat plate. After a few weeks of wiping the heat plate I decided to invest in something enjoyable.
