Sounds like the solenoid is the problem.

Have you tried running vinigar or a cleaner throught with the water or running a wire up it .Sometimes they plug up withlime and will not allow the water to run.Be sure and rinse it well after the cleanser so everything runs clear and you may have to do this two or three times, depending on how pluged it is.

The CW series brewers do not have level probes they run strictly on a timer and a solenoid to control the water flow. So, that said, the problem could be the solenoid. If the brewer constantly drips/runs even when the front "ON/OFF" switch is off then it is the solenoid. If the brewing stops with switch off then it is the timer. The timer is located in the panel behind the filter basket on the front of the machine (6 screws) If the brewer has a manual timer set it to about 2 minutes, a good starting point for a pot of water (1/2 gallon). If it stops brewing then you need to fine tune the timer to give you right amount of water for your brewing method. If it doesn't stop... then you will need a new timer. If your brewer does NOT have a "dial/manual" timer follow the instructions on the backside of the panel to "reset" the brew level. If it does not reset you will need a new control board. Hope this helps.

You have to get to it from the front panel. Remove the 6 screws for access.

Descale the tank and replace the water filter on the coffee brewer inlet line.

You actually don't have to turn off the machine to set the volume. They just want you to be careful.

Check the inline fuse on the element to the ready light.

Hello. If this is the hot water faucet, on the front of the unit, there is a rubber seat that keeps it sealed. Usually it gets a piece of debris, or scale in it with use, or the rubber seat gets worn out and needs replacement. To check, turn off your water, unplug the unit, and drain all the water out of the faucet until it stops, then tilt the unit forward slightly just to get a little more. Now you should be able to unscrew/disassemble the faucet, and pull it out to look at the seat cup, and the faucet interior. If there is scale or debris on the cup, and the faucet interior, it will need to be cleaned, and it may actually require chemicals for scale, if bad enough. If the rubber seat cup is torn, it will need a new one. You can get a new seat at a parts supplier for commercial units in your local area, look in the phone book under "restaurant equipment repair" or go online, plenty of them have a web site. If it is NOT your faucet dripping, we can go from there.

Hope that helps, and thank you.

There is an inline thermal fuse on the right side of the element, check to see, if it has resistance, if not replace.

Somewhere inside you should find a small rotary thermostat. Also make sure the heating element is completely clean by using a quality descaler like CLR. A lot of people use white vinegar but it is not that effective on coffee makers. Make sure the heating element under the carafe is working, because that is heating up as the coffee is brewing. ..

Question edited for clarity and toss in a load of CAPS. It is dated with a non intuitive, none readable code. You can see examples here. Where is my Date Code? BACK OF BREWER Sticker on the lower back of brewer BOTTOM OF BREWER Sticker attached to the bottom baseplate of your brewer. Note: Allow water in tank to cool. Drain water before turning over.

unplug machine and turn upside down and pour out coffee and water mix (if water was in reservoir) If necessary turn over and fill will water and repeat.

Replace and run a pot of clean water thru it.

To locate the date code on your BUNN BT Velocity brewer, you can try the following:

1. Check the bottom or back of the brewer: Look for a label or sticker on the bottom or back of the machine. The date code is typically printed on this label.
2. Inspect the sides or inside the brewer: In some cases, the date code may be located on the sides or inside the brewer. You may need to remove any panels or covers to access the label or sticker.
3. Consult the user manual: If you have the user manual for your BUNN BT Velocity brewer, it may provide information on where to find the date code. Refer to the manual for specific instructions or contact BUNN customer support for assistance.

If you are still unable to locate the date code on your brewer, I recommend reaching out to BUNN customer support directly. They will be able to provide you with accurate information and guide you in finding the date code on your specific model of the BT Velocity brewer.

Normally that would be an easy fix if the water just continued to flow. You just replace the water inlet valve and they can stick open or partially open. But you say if you power off, the flow stops. That sounds like the control board is supplying residual power to it. Control boards are expensive so I would call for service.
