Hi, that is a sticking fill solenoid. You can attempt to clean it out but my be better off replacing it. Easily accessible by removing the front cover from the machine. Located in lower front

The water inlet valve may be stuck open from mineral deposits. You can get rebuild kits for the older ones or just replace the valve?

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.

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.

SOURCE: water wont come out of my bunn coffee maker

The first pot of water you put in the coffee maker just fills the water tank which is then heated up , once it gets to temperature you then pour second pot of water this pushes the hot water out of the tank through the coffee grounds into the waiting pot. This way you can make coffee faster than a regular coffee maker.

I have a bunn cwtf twin,I put new ready lights on both side work for about a week and the they wont light up. and the side the the faucet only brews warm coffee. but the other side does find. HELP

The green ready lights do not last that long. We never replace them on units we service. They are cheaply made. Each side of this coffee maker has its own thermostat. Check to make sure the thermostat is on all the way. If it is check the voltage on the warm side. Make sure it is in the 208v area. This warm problem is 85% the thermostat not set right and or needs replacing.

open the top. there is a trough drain that gets limed up. using a phillips head screwdriver, push through and twist, thereby removing the lime and ensuring proper flow. if water can't get through, it may overflow over the sides of the trough. also look behind the trough to the top of the tank and see if there is any water damage around the seals. if there is, replace the seals

What size breaker do I need to install a CWTF - Twin 4/2? I have 208 volts available. Wattage is 6850.

A 50 amp breaker would be best. To find proper amperage its Watts divided by volts, then multiplied by 1.25 for draw.
