Keeps tripping circuit breakers bunn NHb - Bunn NHB Coffee Maker

Hello

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.

My coffee maker is a Bunn, which keeps a tank of water hot all the time, plus has the built-in warmer plate that you switch on when needed. It, as well as a couple of its nearly identical predecessors, have worked on the circuit with the GFCI for at least a decade and never had a problem. But this morning I see an unfamiliar light shining at me and figure out that it is the GFCI trip indicator. I tried re-setting several times to no avail. So I unplugged the Bunn, which uses the next outlet down the counter on the other side of the sink, and bingo, the GFCI reset. Plugged the Bunn back in and the GFCI tripped again. Plugged the Bunn back in with the switch to its heater element turned off, no trip, but GFCI tripped when I then turned the heater element switch back on. Moved the Bunn to another outlet on another wall, not GFCI wired, and it operates as normal. Brought in a vacuum cleaner and plugged it in where the Bunn had previously been and it operates as normal, no GFCI trip.

All that makes compelling evidence that something in the Bunn is suddenly causing the GFCI to trip. BUT WAIT! Last thing I did last night was pour a canister of vinegar into the Bunn, then cycle the output through about six times, then flush it all about eight times with fresh clean water--this to dissolve and flush out built-up calcium deposits, as is required from time to time. So ample water had been splashed around and through the Bunn about six hours prior, with the possibility of some unusual spillover leaving moisture inside the unit. Running the Bunn on the other circuit for a day or so ought to dry it out to its normal "in-use" condition. Then I'll move it back to the GFCI circuit and try it again. If it still trips, out it goes and I go buy a new coffee maker. If no trip, we are back to normal.
