GFCI tripping


F

In my kitchen, my espresso machine is making the GFCI trip. When
plugging something else (such as toaster), it doesn't trip.
Also, plugging the espresso machine to another GFCI in my kitchen, it
doesnt' trip neither.
So is it due to the espresso machine or shall I just change the GFCI ?

thanks.

Fred.

If the machine doesn't cause another GFCI to trip, assuming that the second
GFCI is working properly, I'd have to assume the first GFCI is at fault and
would change it

Assuming the expresso machine is sitting on a nonconductive countertop
and it trips the GFCI as soon as you plug it in without you or anything
else touching it....

If it has a two prong plug it's probably the GFCI.

If it has a three prong plug it's probably the machine.

Like the previous poster said, try it on another GFCI, but not just
another outlet controlled by the same GFCI.

HTH,

Jeff

My guess is that the GFCI is OK and you have leakage either in the
downstream wiring or one of the appliances connected to the circuit.

GFCI's are calibrated to fairly tight tolerances and it just sounds
like it is working correctly and doing its job.

Remember, there are two ways a GFCI will trip.

1. A current difference in the hot and neutral wire of .005 A or
more.

2. A downstream connection between the neutral wire and the ground
wire.

Many are unaware of condition #2, but this is the reason that there is
a 2nd toroidal transformer in the GFCI. Another safety feature.

thanks for your responses.
I installed a new GFCI, and it was still tripping.
I then tried again to plug it into the other plug I tried before, and I
realized it actually wasn't a GFCI (I couldn't see it as it was behind
a 2 -> 6 plug adaptor :-( Being in the kitchen, I just assumed it was
GFCI, but it wasn't).
So now I know my espresso machine is at fault.
I opened the expresso machine, tied all connectors I could find, tried
it again, and it made the GFCI tripped.
Next thing I tried: changed the cord. I had one at home, so simple
enough. One thing I wasn't sure about is that it had blue, brown and
yellow-green cables (the espresso is made in Italy), but the cord I had
was the typical black, white and ground.
I connected in: black/brown, white/blue and yellow-green/ground (found
that info on the internet)
When plugged in, it doesnt' trip anymore. However, if I activate the
pump, it trips again.
Any idea before I take it to repair. I probably should do that, but I
bought it used on ebay, not exactly for cheap, and sent it to repair
about 5 months ago (they cleaned everything), so my 10 years old
machine already cost me more than a new one :-(
I would hate to fork another $100 on it...

thanks in advance. Fred
