You need to see where it is leaking from because it may not be from the tank. If there is a overfloe cup and there is water in it the machine may be overheating. It may also be and inlet solenoid sticking open. Check if there is a overflow cup or if water is continuosly allowing water in. Hope this helps. WWW.MidstateBeverage.com

This is usually caused by the thermostat allowed the machine to boil the water. We offer an out-of-warranty exchange to get a new machine. If you will call customer service at 800-352-2866, we will be happy to assist you in getting a new machine.

The white neoprene piece from the seal kit is on the bottom, then place the metal washer in and the bolt on top of it. Then insert the black plastic piece on top and insert into the sump area and tighten it down with a screwdriver. If you need further assistance, please call customer service at 800-352-2866.

Please contact customer service and a seal kit can be sent to you that should fix your leak-it is successful about 90-95% of the time.

Sounds like you need a new thermostat.

Hello. Here is what could be happening. Your brew timer may be having a problem where it is re actuating on it's own, in which case it would need to be replaced, and re calibrated. The other possibility is that the start switch is making contact internally, and telling the brew timer to start again. Your unit does not show it having a level probe, so most likely it is not overflowing due to a flooding condition. After you brew, turn off the lower heat switch, this will remove power to the brew circuit, if the problem stops, then you know it is one of those 2 things, and I would try the start switch first, as it is a cheaper item to replace than the timer.
Here is a link to your brewer manual with part #'s etc..

Hope this helped, and thank you.

There is a brew timer on the left side of your machine near the heater switch. you need to remove an access panel to access it. turn this down a little, let the water heat up, then try another brew. Adjust as needed, brewing another pot between each setting.

You could have scale building up on the heating element and thermostat probe. try running a 1/3 white vinigar - 2/3 water mix into the brewer, let it heat up completely, then run several pots of clear water through the unit. keep pouring water through it until the vinigar smell is out of the water,

you can always clean a coffeemaker with vinegar, but always pour in cold, so you can do it twice or more, but dont re-use the stuff you just used, wait till it's cold or just use some other.after use clean by let water through 2 or 3 times, (also only cold water)

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.

Where is my Date Code? - BUNN

More here https://www.google.com/search?q=Bunn-o-Matic+HB+coffee+maker+read+the+date+code ..

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.
