Bunn NHB leaking from bottom

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!

These models have a plastic pour-in tray just under the top lid. The plastic on these trays gets brittle over time with the heating and cooling, and they crack where they mount to the tank. The only real way to repair this is to replace the pour-in tray, but these are not sold anywhere that I have found. You might be able to find a used one at a Bunn dealer in your area.
I have seen some people do a temporary repair by putting a washer under the mounting bolt and sealing it with silicone, but this is a temp. fix at best. By the way, the reason that the water appears to be coming from the bottom of the machine is that there is no other place for the water to come out after it leaks from the top.
