Hi - Go to the Bunn website, , and click on their Customer Service link. I seem to remember a recall for that problem. You can call their toll-free number or write to them from their website via the CS link.

Hope this helps!

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.

Our FrancisFrancis espresso machine, started tripping the circuit since we moved from london to singapore. Is it a problem with the machine or the machine is incompatible with the Singapore's electric...

The electricity power is the same as UK 230V and 50 HZ even with same plug shape.
The tripping of the curcuit braker is due to a short in a power line inside the machine.
The most posible part is the heating element and second athe solenoid valve. Last with less posibility is the vibarating pump.
The only way to identify is to open the top of the machine and by a use of leectrical tester you can mesure the above parts live lines if they have an earth contact and replace that part.
Give emphasi to the boiler element.
Good luck

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?

If i try to make more than 6 or 8 cups in my 10 cup bunn coffemaker. The coffee grounds overflow . This is a new coffee maker and we find a mess almost every time we make a pot. We have alwats used bunn...

This can occur with the use of finer ground coffee or use of soft water, filtered water, or bottled water. If you will call 800-352-2866 with the model and date code, we can send you a flow restrictor sprayhead which will alleviate this problem.

When i plug the unit in, the reset switch on the outlet immediately shuts off

Assuming that by "switch" you mean circuit breaker, this is indicative of an electrical short. The circuit breaker is tripping to protect from an overload hazard.
You need to rule out if the outlet itself is bad vs. faulty electronics in the BUNN itself. Here's how you can do that:
1. You may have too many appliances drawing power simultaneously from the same outlet or from other outlets sharing the same circuit. If there are other appliances connected, try removing them temporarily to see if the BUNN still trips the breaker. NOTE: If you are using an extension cord, timer or a surge protector, remove it and connect the BUNN directly to the wall socket. Moreover, do not operate appliances on outlets controlled by a dimmer or a switch.
2. If you are uncertain as to what the cause of the problem is, one option is to relocate the BUNN to another outlet on another circuit in your residence to see if it trips that too. If so, the electrical components in the coffeemaker itself are to blame and you should contact the manufacturer and/or an authorized service center ASAP.
3. If the BUNN was the only thing plugged into the outlet when it tripped, try plugging in something else that draws a similar amount of power/wattage to see if it also trips the circuit while running. If so, your outlet is the culprit and/or the circuit is being shared by too many other outlets in your home (particularly true of old buildings). Call an electrician and/or your property manager to inquire about a solution.
4. Type your BUNN model number and the word "recall" into a search engine. If there is a recall in effect that seems to involve the problem you have encountered, contact BUNN for your service and replacement options. If you determine that the outlet is working correctly and the circuit is not overloaded and you suspect the brewer is at fault but there is no recall notice, consider filing a report with BUNN and/or the Consumer Product Safety Commission. This is a serious safety hazard and needs to be reported to the appropriate parties.

My Bunn coffee maker is tripping the circuit breaker in my house?

Switch to a different plug. The appliances on this line cannot support the energy needed when a coffee machine comes on...they use a lot of juice.

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.

Trips GFI circuit brakers

First of all, lets clarify what is going on. You say it trips the GFI breaker, so I'm assuming that it is not a GFCI receptacle that you are plugging into. So you are going to the electrical panel and resetting the GFCI breaker.  If it were a GFCI receptacle, have you tried other loads in this receptacle for 30-40 seconds, ie: Toaster, hairdryer, coffee pot? If everything works fine then there is something wrong with the ESP8XL. It would seem that there is a leakage path to ground from one of the conductors. If it is new, bring it back.

We have a Bunn coffee maker manufactured in 2006. Any time we try to use it, it blows a fuse

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.
