I have a Bunn CWTF TWIN coffee machine.....the one side will not stop pouring water out of it....was wondering if there is a replacement part or parts to fix the problem

SOURCE: coffeemaker

The Bunn coffee machine has an internal tank used for holding approx three potfulls of water at just below brewing temperature. When you add water for a potful, the thermostat senses cold water and starts the brew heater. The water level inside the tank comes up and goes through the sprayhead. This "surge" of water, that you call drips is normal. The hot water stratifies to the top of the tank, just like an electric water tank in a house. The internal pot heater kicks in and boils the water already in the tank, raising the water level in the siphon pipe to the sprayhead until the reservoir under the add water opening is empty.

It sound like you are either missing the sprayhead or the temperature isn't hot enough. Check first to see if the sprayhead is there. It fits under the brew basket and looks like a little shower head - it's round and has usually five or six little holes in it. If it is missing your coffee will be weak due to the water not being spread across all of the grounds evenly.
The other thing to check is the temperature. Depending upon where you live the water should be between 185F - 200F. If the water is below that temperature the coffee may look like tea.

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

Yes Bunn will send you a repair kit free of charge. Just apply a bead of silicon below the rubber gasket before you tighten it down and it will solve the problem.

Our Bunn VPR was delivering luke warm coffee. The problem was lime scale buildup on the heating element. I recommend using a cleaner such as Brew Rite or a vinegar solution. If it still does not heat properly, unplug and remove the heating element for cleaning. This corrected our problem.
