Blows breaker Blows gfi breaker blows regular breaker

    I have a Bunn coffee maker that's been in the closet for a year or two. It worked great and then one day it blew a breaker. Plugged it in everywhere and it kept doing it. Plugged other appliances in and the Bunn was the only thing it happened with. So I bought a new coffee pot and tucked this one away. But I miss my Bunn! I figure it must be in the cord. Any ideas out there?

If you have a multimeter you can set it to ohms and see what value you get between the prongs on the plug. it shouldn't be 0 ohms. there should be some resistance. if you have it off--there should be no resistance (OL). and if you have it in the on position you should have some resistance. It's a fairly simple device when you take it apart. I bet that if you open it up you'll be able to see the problem.

I have never seen the inside of a coffee maker but you are describing a short condition. A conductor wire is in contact with a grounded wire. Unplug the coffee maker and disassemble. If the short is in the wiring, it will be readily identifiable either by melted (scortched look) insulation or a wire that is loose and touching a ground wire. Consider the cause of the short. If it looks like a heating component caused the short, then reconnecting or retaping the wires should solve the problem.

Seacoast magic plus keeps tripping gfi breaker

try in different GFI outlet, if it trips the new one, the coffee maker is dangerous and you should return/replace it, it has a short.

if it doesn't, replace the GFI outlet, it is old.

Our Magic Comfort plus is 4 years old and it keeps blowing the gfi instantly when I plug it in. I have had this problem occassionally in the past and it resolves after one or two gfi trips. Now if tripo...

The problem believe it or not your gfi is warn out. I am actually surprised it lasted as long as it has and surprised it worked at all. Espresso machines use a huge amount of power when turning on compared to maintaining power. When espresso machines first turn on the take a huge surge of power to start heating up the elements. Normally you want to put an espresso on a circuit /outlet that is directly to your breaker that is at least a 20 amp breaker. By code kitchens and bathrooms, where an outlet is near water, has to have a gfi outlet, this is for safety for something plugged in near water so it will trip if accident happens with appliance near water. The bad news there not to good with high demand power appliances such as espresso machines. Yes , you can replace the gfi circuit, by turning off main breaker, unscrew gfi from wall, pull out, and undo wires, and copy exactly when re-wiring the new one. Then turn on main breaker again. NOTE: you can buy a gfi all most any home improvement center, lowers, home depot, ace hardware etc.... Think of a gfi kind of like a advanced in line fuse, they do wear out. BUT AGAIN, my advice is plug it in a outlet that does not have gfi and is on a main breaker of at least 20 amps if you have that opportunity to do in your kitchen area. Hope this helps you, thank you....... MIKE

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.

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.

Ground fault issue

This is not an unusual issue, but an unusual fix. When appliances that use water and heating elements use a ground fault breaker, it often thinks there is a problem to ground, since it is not the regular short to ground like an element. Move it to an area that has a regular outlet, and turn it on the first time. From then on, it should work right.

Kitchen GFI breaker goes off when machine is plugged in - off or on

Try plugging it into another GFI outlet. If it still trips, it's a problem with the coffee maker wiring and is cheaper to replace it than fit it.
