Re: 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 www.fixitclub.com/Small_Appliances/Coffee_Maker.shtml 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

If it is not heating it won't make coffee so check if the hot plate is heating up. If it is heating then I would be looking at the one way valve in the pipe by the element. Be aware that some parts for this model are now obsolete so it may be a good time to send it to the tip.
This model of coffee maker has an adjustable heating element beneath the carafe - ensure the temperature setting for the carafe is high enough to keep the coffee hot.
If the coffee is not brewing hot, the initial heating element/coil may have failed. Removal of the heating element is somewhat problematic and will require disassembly of the water container and base of the coffeemaker, and will likely need to replace the heating coil contained in a plastic sheath. Ensure you take a look at: http://home.howstuffworks.com/coffee-maker2.htm

No. This coffeemaker is not built to be serviceable in that regard.
You can wipe down the inner-sides of the reservoir for a slightly better maintenance cleaning. But, 4 cups of pure white vinegar (no water added) in the hour-long cleaning cycle followed by two pots of fresh water in the brewing cycle is really the best way to clean the rest of the inner-parts which contact the liquids.
If your real purpose for your question is how to resolve the elongated brewing times, I'm afraid that is a symptom of damage to the heating element. This too is not serviceable.
The heating element will naturally degrade over time. But, it can incur sudden damage when the reservoir is refilled with water too soon - while the element is still hot. Because of the simple design, if the coffeemaker is one, then both the warming plate's heating element and the reservoir's heating element are on. So, after a brewing cycle is complete, the reservoir's heating element stays on. Without any in the reservoir to keep it cool, the heating element superheats. So, if water is put in the reservoir while the coffeemaker is on or before the element has adequately cooled, the sudden burst of steam from the water contacting the element can be quite violent.
You can get a faster brew cycle by putting warm water into the reservoir and making coffee right away. But, depending on your hot water supply, the coffee may not taste quite as good.
The heating element has gone bad. Since it is not a user-serviceable part, I recommend replacing the coffeemaker.
In the future, make sure you do not add water to the reservoir unless the coffeemaker has been turned of for at least five minutes. This will help prolong the life of the heating element.

Hi, If you have a Farberware, Just look into the bottom of the pot. There you will see what looks like a hole in the pot. That is the high heating element, under the pot, when you go to make coffee the pump ( rod) sits into the hole. When you turn it on to make coffee the high heating element that the pump is in gets very hot and starts pushing the water that is in the hole to the top (that is called perking) the hot water goes over the the top and the drops into the coffee, This keeps going on until the thermostat feels it has reached 190 degrees or close to it and turns the high element off. While this is running it's cycle the keep warn is on helping the water to get hot, when the main element is off the keep warm element that runs around the bottom of the pot stays on all the time the pot is plugged in. Should the coffee get to cold the thermostat will turn the main heating element back on until it is back to 190. This system was developed by Farberware and a lot of makers copied it, But Farberware sold the pots and was known for a FAST and HOT cup of coffee. Farberware started making them in China and the pots are having a hard time keeping it up to American standers, and parts are very scarce.Farberware USA pots have been around a long,long time and are still going strong . I hope this helped you to understand how the pot works.
The problem is the keep warm element. The reason, your pot perc's and it gets hot near the thermo, the thermo turns off the main element. The keep warm element is not on so after a small amount of time the water cools and the thermo turns the main element back on again, thus making the water hot. The K W element is supposed to be on all the time the pot is plugged in, it is instrumental in perking the first brew making it really hot, the thermo turns off the main element and the K W element keeps the water hot. The K M element is very a easy fix, it is the small looking white rope that runs around the bottom of the pot. You have 1-nut and 1- screw to remove. When removing the screw from the main element you must hold the (leg) that the K M element is screwed to so it does not bend and brake off. Take your time and be firm with the pressure you apply to the screw, while holding it with a pliers Good luck. bobbyone

Underneath the hot pad that the carafe sits on, there are two thermal fuses that are inside tubes that are clamped to the heating element with spring clamps.
Remove the bottom of the unit (5 screws), unclamp the thermal fuse tubes, slide the tubes to one side and check the each fuse with an ohmmeter. If one of them is open, that's your problem.
To check the water temperature you need to run a pot with the sprayhead removed. Most Bunnomatics have two forms of heating. The primary heat source is the heater element. It's job is to heat water to the temperature set by Bunn factory technicians. The second heat source is what is called a "keep warm heater". This heater is always on and keeps the water temperature at about 180 degrees. This saves on long heating times while the coffee brewer isn't being used. Now, if the main heating element goes out the brewer is still gonna send about 180 water to the brewbasket. By the time is gets from the air gap in the brewbasket to the grounds and filter it looses about 10 degrees. Coffee (regardless of what that non expert said that burned herself when she put the coffee between her legs says) is brewed at between 190 to 205 degrees for a good cup of coffee. With lawsuits I think alot of restaurants have taken the brew temp down to about 193. So your coffee maybe hot but if it is only using the blanket heater it won't be hot enough to make a good cup of coffee. So check the temperature by using a good electronic thermometer purchased at most hardware stores. If the temp is good start looking elsewhere. The first place is after you brew a pot of coffee do you have a "star" pattern in the used grounds, you should. If not remove the filter basket and run a pot of water into the pot. You may have to get a pan that will fit under it to catch the water if it doesn't drop into the brewer's decanter. You don't wanna make a watery mess. It is imperative that all the holes in the sprayhead are clear of grounds and water is running, not dribbling from them. A clean brewbasket and sprayhead are everything to taste. Also the temp must be above 190deg and It shouldn't take more than three minutes from the time you finish pouring the water in the top until you basically have a full pot (not counting some small dripping at the end).
