Bunn blows fuses

This is usually caused by the tray where you pour in the water leaking where it mounts down to the tank. it's probably cracked just enough to allow water to seep out, crossing wires on top of the tank, causing a dead short. There is also a seal that goes between the pour-in tray and the tank that sometimes starts to leak. This tray can be replaced if you can find a used machine that doesn't have the same problem. Before you buy one, though, you should take the top of your brewer off, remove the pour-in tray (careful - they get brittle over time) and look on the top of the tank for signs of water seepage. If there are no signs, then your heating element is most likely blown.
