Usually this happens when there is an electrical problem with the brewer. If you will call 800-352-2866 with the model and code date from your brewer, we will be happy to assist you with this issue.

Plug another small appliance into the GFI where the coffee maker is pluged. If it doesn't trip, there is a short in the wiring of your coffee maker.

Can't figure out why when I plug in my bunn vps commercial coffee maker it immediately trips the circut breaker???


There is a couple things can cause this to happen.

Number one make sure you have nothing else added recently on that circuit, where you have had your machine plugged in. If something was added on that circuit, something that is always running like a fridge, that could be overloading the circuit, sense coffee machines use a huge amount of power at start up. If your sure nothing of that sort has changed then next is:

Number two, make sure you have cleaned the machine, you know descaling and making sure there is no restrictions. If this is good, then next is:

Number three, it appears you can have a short. The heating element going bad in the coffee maker. If the thermostat or heating element is pulling more power boost then normal because its going bad or a short this will trip the breaker. What I would first do, is run yourself a extension cord from another outlet that for sure is not on same breaker. If that breaker blows, then you know for sure it is the machine that is causing this, then we are back to the heating element or thermostat on off regulator.

What i have done is located the manual on your machine, that besides gives you a lot of information, it also gives you trouble shooting tips and schematics of the parts and wiring diagram for you machine. Here is the link to copy and paste in your browser to download the manual.

Please if this helped you, rate my free solution and a pleasant testimony would be nice to help me and others on my efforts of helping you. Thanks So Much, Mike from Fixya.

We unplugged our Bunn and left it unplugged overnight to do some painting. When we plugged it back in the light doesn't come on the warmer and the water does not heat.

The unit is not getting power. If the receptacle is protected by a GFI, then press the Reset button. Otherwise, check that the circuit breaker (or fuse) to that receptacle isn't tripped.

How to fix a bunn coffee maker that trips a gfi

Every time I plug in my bunn coffee maker, it trips the GFI. But when I plug it into another plug in my kitchen, it will work, but it seems like the water reserve is not right. It blows too much steam and the top starts lifting up from the pressure of the steam, then it starts leaking out the top left side. Then if I pour enough water to make 10 cups, it only makes 6 or 8. The coffee maker is only 3 years old, what should I do?

The gfi trips every time I turn it on

Chances are while you have a 20amp circuit in your kitchen the gfi you are plugging into is rated at 15amps. First make sure your outlet is connected to a 20amp circuit breaker and then change out the gfi for a 20amp one. This coffee pot is more for commercial than residential usage, I had the same problem until I changed out the gfi plug.

When i plug it in it trips my gfi and it is not on

This can be caused by one of two things. (1) The GFI plug has a problem: it could be broken behind the face plate, or some of the wires in the box are so close that when you push a plug into the outlet, they touch and trip the GFI. (2) The other source is due to a defect in the appliance between the cord and the power switch. That is why the GFI faults even before it the coffee maker is turned on.

Have the outlet checked thoroughly and make any needed adjustments / repair /replacement and reconnect the coffee maker again. If it trips, the coffee maker will need to be serviced. DO NOT use the coffee maker in another non-GFI outlet until it has been checked out. The chances of electrical shock or burns is significant until the problem is found and corrected.

Keeps tripping circuit breakers bunn NHb


Coffee makers have a heating unit in them which draw a lot of current. If it is on the same circuit as refrigerator, toaster and other it will trip the breaker. Also, some breakers are more sensitive than others. Have an electrician run a separate circuit for the coffee maker outlet. Try running it in the dining room outlet, which I hope is separate from the kitchen outlets. Is the house old? Older homes have a lot of mixed up wiring.

GFi breaker blows

There is an electrical problem with the brewer. If you will please get the model and date code located on the bottom of the machine, and call customer service, we will be happy to assist you with this. The machine has a 3 year warranty and if the machine is 3 years old or less, it will be replaced at no cost. If it is over 3 years old, it will be replaced at a reduced price.

A short condition has severed a conductor wire inside the coffee maker. Seems to be a common problem with coffee makers as the wires are in close proximity to heating devices.
