Re: My 2006 Bunn blows a fuse when used
This sounds like a short in the main heating element. If you are within your 3 year warranty, Phone Bunn and talk to their warranty department. They will give you a RMA number and give you further instructions. If not, there are no replacement parts available for these brewers.

The bunn VPR is a gravity brew system what you put in if the tank is full is what you will get out. So pour water in until it flows out the sprayhead, then turn machine on, when it heats up fill up a carafe with water (1.9Liters) and put in your filter with water and brew. It is a good idea to pour water in every morning to make sure tank is full especially if you are not using brewer on the weekends.
Sounds like your timer part #32400.0002.This is the new type timer which replaces the dial timer.Another thing is does this happen when you turn on the on/off switch? I would also check your liquid level probe in top of tank.Always a possibility bad liquid level board.If it only does this when you push the brew button the timer is bad.
The Bunn coffee maker does not operate as most coffee makes do. You cannot leave the Bunn in the off position and then just flip the switch to on and pour the water in. You will always get cold coffee if you do this. It takes time for it to heat the water. The On/Off switch should be left in the On position all the time. This keeps the water hot in the tank, thus providing hot water when you need to make coffee. You then just pour the cold water in the top, shut the lid, and have a pot of coffee in 3 minutes. The On/Off switch is a vacation switch, and you use it only when you are not going to use the coffee maker for a couple of days. Older Bunn coffee makers did not even have an On/Off button. You simply unplugged them when going on vacation. So turn the switch to the On position and leave it there. The unit will then work as designed. Forget how other coffee makers work, this is a Bunn and it is the fastest coffee maker you can buy and must be left on all the time. that way the water stays hot and the unit will keep it that way.
It sounds like you have a pour over model and the problem is the tank
isn't full. Turn the machine off (or unplug it). Put a pot on the
warmer like you are going to brew coffee. Pour clean cold water into
the top until it starts coming out the sprayhead (above where the
coffee grounds go). Now plug it in and turn on. Let it heat up then you
The way your machine works is that there is always
about 2-1/2 pots of water in the tank. The water you pour in to make
coffee is actually pushing the hot water in the tank out. So, if you
don't fill the tank before using it, you may be hurting the heating
element since it isn't totally submerged in water.
You didn't mention which fuse it was that blew; I assume you mean a house fuse, not the Bunn's.
Since you mention a fuse rather than a circuit breaker, again, I assume this is the screw-in type that must be replaced each time it fails.
Check your Bunn for the rated power consumption; it should be shown somewhere on the machine and is likely somewhere between 1000 and 2000 watts.
You need to find how much current the machine is drawing.
Divide the given wattage by your line voltage which is probably (if in the US) ~120 Volts.
For example: (from the Bunn) 1200 Watts/120 volts = 10 Amperes
That means that when the Bunn is heating water, it will need 10 amps just for itself.
If, for example, you have a microwave oven using that same fuse that has a rating of 1000 watts power to cook with, it will actually draw ~ 1400-1500 watts from the wall plug.
Again, 1500 Watts/120 volts = 12.5 Amperes
Now we have a total of 22 1/2 amps of current if both are operating at the same time or if any other appliance such as a toaster (also draws a bunch) is being used, you will most likely blow a 20 amp fuse if not instantly, perhaps after a few minutes.
Fuses are designed to blow in a few milliseconds if hugely overloaded or to be patient for a minute or two if the over-current is mild; say 21 amperes.
Over-fusing may be dangerous since the fuse rating is related to the gauge of wiring in the circuit it protects.
This means that you need to move the Bunn to a different circuit so you don't accidentally exceed the fuse rating with two high-powered appliances if turned on together.
