Wehn I refill the reservoir of my Bunn coffee maker, it makes a loud, kind of loud boiling sound, almost popping..it is still working fine but I wonder if it is the heating element starting to go out. Or does something need cleaned? I think it is about 4-5 years old. It is a 10 cup home model.

Actually I found out it was needing a good dose of vinegar. When I cleaned it well, it quit making sounds and works perfectly. In the meantime I had bought a new Bunn but kept it in the box until the old one gave up the ghost. Thanks for you help. My coffee pot never seems to get left on long without making coffee as we always turn it off when out of town.
