Leaking from top of tank; Call for service as this is an electrical hazard. *** the following is for information only. *** * Replace any worn gaskets and silicone tubes. * There may be cracks in the metal pipes. Hard to see, but there, if you remove the lime deposits. * check the top tray nut if the gasket to the tank is missing. It's about an 1-1/4" round washer with about a 3/4" hole. Usually made of white silicone rubber. It seals the fill tray to the tank. Leaks often. * Bunn equipment can last quite a few years (decades?) but the gaskets do get hard and the tank needs to be water tight to work properly. Since this is already an old brewer and you've saved money rebuilding it. Suggest going further by replacing all gaskets. Yes they do need to be snug with no cracks. Aloha, ukeboy57

If its been changed to 220V plugging it into 120V won't damage anything, it just won't work. Replace the plug with a 120V plug end and plug it in. If it works its120 if it doesn't, its either a 220V setup, or you have a blown fuse in the unit/power supply or some other defect.

the plunger for ur solenoid valve assembly might be stuck in open position ... ur click sound maybe came from ur funnel lock during brewing. water shots from the fill or oveflow cup due to contoniuos supply of water , try to close ur main water and c if water will also cease

What about Bunn water level? Too high? Too low? Not filling? Leaking?

replace the switch

Most likely cause is that the seal between the water reservoir and the tank is leaking. Not uncommon. If you can find a replacement seal go for it, otherwise the old one can be made serviceable by coating both sides with a thin bead or layer of clear silicone. Allow to cure for 24 hours before powering the coffee maker back up.

delime the sprayhead and reservoir drain (in the top) with a deliming spring or a screwdriver. to delime the tank, put a half gallon of vinegar in the top and catch the hot water as it comes out of the sprayhead. leave it sit for about 20 minutes and brew at least 8 times (w/o coffee) or until you can no longer taste vinegar

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

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.

Not sure your model name is correct and we always need numerical model names here. Bunn are such a well known name in coffee machines, I find it disappointing that they say ANY machine is not repairable. I found some Training Manuals and I found a 'Thermostat Limit Kit'. https://www.google.com/search?q=bunn+grab+fast+brew++temperature+limit+switch The search query would be Bunn (numerical model number) temperature limit switch ..
