Why is my bunn coffee leaking water from the bottom when i add water

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!

There are 3 seals in your unit that could cause your problem. there is a silicon seal right under the pour-in tray, and two on the top of the tank. one of those is for the thermostat, the other is for the sprayhead tube. any of these could leak, causing water to come out the bottom of the brewer. One other thing that can cause this is a scale buildup between the pour-in tray and the tank.

Please get the model and the date code from the bottom of the machine and contact customer serivce. Depending on the date code, there might be a seal kit available or the machine can be replaced at no cost if 3 years old or less. If it is over 3 years old and the seal kit isn't available, the machine will be replaced at a reduced price.

SOURCE: Bunn Coffee Maker Leaks out the bottom

I have an older BUNN B10 pour-o-matic that I thought was leaking from the bottom. Upon close inspection, I found that it was leaking from the worn out washers located on the top of the tank, allowing water to run down the sides of the stainless steel tank. There's a great fix offered on Fixya.com that suggests going to a hardware store and buying a Gardner Bender GHG-1575 rubber grommet with a 3/4" hole and install it into the large hole in the basin. Then place a metal washer on top of the grommet and snug it up with the threaded fitting. Many folks say it's a great fix. I went a different route. I called BUNN customer service and spoke to a very nice woman who understood my needs and sent out a free repair kit that contained a new fitting, washer, and seal. I received it in a few days and it's working great. Beats going out and buying parts for a work around repair. BTW, the repair kit is called "Universal Retail Seal Replacement Kit #37091.0000"
