Thermal fuse is blown. it is located in the top, right rear of the machine in what is now browned tubing. you can either bypass the fuse with a jumper, or get a new part through bunn (800) 352-BUNN (2866)

SOURCE: my bunn coffee maker leaks

You need to replace the washer kit inside the top of the maker. Remove the 3 screws that fasten the top and lift it off. You will see the rocker leaver that allows the water to flow into the tank. At the point where the rocker stops the water there is a series of washers that degrade from the heat over time and allows the leak. The washers are very easy to replace. The problem is finding the washer kit. I found it at: www.buyitnow64.com for $3.95 plus shipping (FedEx is only $9.98). I bought 2 (one for backup) kits.The original washers lasted almost 6 years. I had repaired this problem before with a washer from my shop but it broke down rather quickly from the direct heat from the tank. This washer kit is a Bunn washer kit that is supposed to fit all Bunn machines both residential and commercial.
Hope this helps. It took me 2 hours on line to find the washers!

open the cover on the brewer- depending on your model, it could be the front or the back cover. look for a brew timer dial. turn this up slowly, running a brew each time to see if you now have a full pot

SOURCE: I need a wiring diagram for a Bunn BX coffee maker

I do apologize but these diagrams are not available. What is the problem with the machine? If you will get the model and code date from the bottom of the brewer and contact customer service, we can help resolve your issue. The machine carries a 3 year warranty and if it is 3 years old or less, it will be replaced at no cost. If it is older than 3 years old, then it will be replaced at a reduced price.

Our coffee is weaker and bland the past few days, and we are using the same amount of coffee, and the same brand, what is wrong with our coffee maker?

If this is a BUNN, the problem is the heating element is turned of by the switch on the side or the heating element is bad. Feel the rear tank area of your unit. it should feel warm to the touch at all times that is is plugged in. The water must be up to temp to work properly.

Most likely suspect is the thermostat, however you might want to check the limit switch also(located on boiler between elements).

Adjusting the temperature

Our Bunn VPR was delivering luke warm coffee. The problem was lime scale buildup on the heating element. I recommend using a cleaner such as Brew Rite or a vinegar solution. If it still does not heat properly, unplug and remove the heating element for cleaning. This corrected our problem.

Most likely this is your heating element, but it could also be your main thermostat

The water is not heated when I put my Bunn coffee maker on

If you plugged it in before water started coming out of the sprayhead (about 2 pots full of water poured in) you might have burnt out your element, But lets start with a simpler answer. Did you check the main burner switch on the side of the tank?
If so, then I would suspect your main heating element

Bunn coffee maker trips the breaker

It is possible that you have a short in your limit thermostat, but most likely this is caused by small holes in your main heating element. these units start to split length ways down the element, causing a short to ground through the water. These elements are readily available at your local Bunn repair shop.
