Hello. I have seen the tank heater not blown, however, it has a high resistance to ground through the water, replace it, and all is fine. You would need a good multimeter to test this problem, there must be a small crack in the sheath of the element, and is able to bleed a little leakage through the water, not enough for a normal outlet, but a gfi, no good.

Hope this helps, and thank you.

Unfortunately, it seems that China is the only one manufacturing the thermal fuses and they are notoriously inaccurate, tough to find as replacement parts and most often they are spot-welded to the heating element's leads, something most owners can't accomplish.Soldering them isn't wise since they are located close enough to the heating element to cause solder to flow.
There is a type of barrier connector common in Europe, hard to find elsewhere, that uses screws to hold the wires to be brought together; one hole that goes through a metal channel and has screws mounted at 90 degrees so that each of the wires are held by one screw.I have replaced the thermal fuses this way with some ancient US made stock (once had reason to keep these on hand) that is rated for lower temperatures and therefore must be mounted slightly farther away from the heating element. I wouldn't do this to someone else's coffee maker since I cannot guarantee the effectiveness of the thermal fuses installed.
Do NOT decide to just jump the blown thermal fuse with a piece of copper wire. I know of one case this was done and the machine failed to shut down on time and a Formica counter was set ablaze.
Some cases of circuit breakers tripping may be those which combine a GFI (Ground Fault Interrupter) into the breaker and will trip if even a minor ground current is sensed and this can occur from moisture trapped inside the machine.This type is commonly found in newer homes on circuits located close to any exposed plumbing to prevent death by electrocution.

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

As soon as I turn on the boiler it pops my GFI instantly. Would this be the element or wiring or what?

Sorry to say but its your heating element. When they go bad it exposes the element to the water and creates a direct short. This short is what trips your GFCI. It needs to be replaced.

The burners on the coffee maker are not turning on

Does the machine heat the water and make coffee? It is odd that both warmers don't work because they are controlled by two different switches. The bottom burner comes on with the tank heater and thermostat. The top heater is one switch by itself. If you are handy with a small screwdriver, unplug the machine, take the top plate off and check to see that all the wires are connected to the elements and to the switches. If you can check the elements to see that there are no burned spots, usually the elements are good. My opinion is that the attachment from the main terminal block where the wire enters the machine has a loose wire.

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?

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 GFI outlets

The key here is to identify the problem as being either the coffee maker or the GFI receptacle... a simple test can be done as follows...
Try plugging the Coffee Maker into another GFI receptacle .. you may have one in the bathroom? If it trips that too, then you have an internal wiring problem with your coffee maker.. if it doesn;t ..then your GFI receptacle may be bad or on the verge of going bad .. either way..this should narrow the problem down to one or the other.. hope this helps..

Power to the machine

Verify that there is power at the outlet. check power cord for breaks or scuffs. Check to see if there is a fuse in the back of the machine. I fall else american.
