there is an overfill tube in the rear that may be leaking.

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.

The silicon seal inside the coffee maker tends to disintergrate. Bunn Inc. does not sell parts for the inside of the coffee makers, but a seal kit can be purchased through a small appliance repair center or repaired for a small cost. Kit is about $8.00 at most places.

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"
