I've been having a grand time with a gaggia paros. I reseated the boiler
and replaced some gaskets. I also used a sealant between the boiler and
the grouphead. I put it all together except the top shell and ran a couple
quarts of water through it to look for leaks. Everything worked fine.

After the machine got nice and hot, I decided to pull a shot and discovered
the machine was now hot in more than one way. I shut it down, took the top
off and looked for water or a stray wire, but didn't see anything. I put
it back together and tested it. No shock.

I ran some shots through it. Looked for leaks. No problems. A little
later I decided to pull another shot. I got another shock. I opened it up
to look for any moisture. No luck. Checked the ground. It was okay. The
thing has about 6v of DC running through it and I can't figure out where
it's coming from or how to fix it.

Any thoughts would be appreciated.

1) Do you have the machine connected to a GFCI circuit? If not, do so.
2) Check the outlet for proper grounding with an outlet tester. They
cost about $5-7 or so and are very easy to use. Like one of these:
http://www.mrtool.com/browse.cfm/4,470.html
Establish that the outlet is wired correctly and has a good ground,
3) Check that there is continuity between the machine's exposed parts
and the ground lug on the cord when the machine is not lugged in.
4) Plug the machine in and check for continuity between the case and
other exterior parts and the ground connector of the outlet when the
machine is off.

What you may be feeling is an inductive current, but it is building up
because of a bad ground. You may need to add a grounding wire between
the machine's internal ground lug and other parts of the machine as
you may have isolated the ground lug when assembling the machine.

The small DC current you feel may not be dangerous but points to a
missing ground connection somewhere that may become so.

If any of the above sounds foreign to you, consult a professional as
this can become dangerous and even fatal.

Well, a new development.

I tried grounding the machine with another wire. The machine didn't turn
on. I removed the wire. Now the machine won't come on at all.

I'm afraid I'm losing my battle against this machine.

. . . and the plot thickens.

I opened up the machine again to see if there was a fuse of some sort that I
didn't have to wait six weeks to receive and found the source of the shock.
At some time, one of the wires inside the machine had been very slightly
cut. When I opened up the machine to replace the gaskets the tiny cut in
the wire moved to touch the metal.

Now that that's fixed I am extraordinarily annoyed that I have probably
created a worse problem for myself when trying to fix the first problem.
So, any ideas on what next part I need to buy?

When this thing is over I'll have replaced most of the machine and will be
wondering why the heck I didn't just shell out the cash for a brand new
machine. Of course, then I wouldn't have this great educational
experience.

Hey Randy.

It's not hooked up to a gfci.

I did check the outlet and it's properly grounded. The lug on the cord is
fine.

Here is where I'm getting confused. The plug itself has three prongs. The
plug has three holes and three wires. The male part of the self locking
plug is plastic and has two connectors. The two wires that are connected
here are blue and white. I can't figure out how this ever made a
connection to the ground, but a ground connection must have been made
somewhere.

I will keep looking . . .

Thanks for your help!

I am not certain where this comes from but I believe it is due to
leakage of current in the heating elements of the boiler. If you can
feel the voltage, it could KILL you.

Don't bother measuring DC volts -- there are none, you are just getting
a spurious reading. Measure AC.

I had a very similar experience about 10 years ago with my personal
Gaggia Classsic.

I found over 80 volts AC from the case of the machine to the steel
kitchen sink and the green ground wire at the outlet. -- in Europe it
is greeen/yellow.

the machine I mention only had only a 2 wire plug, with NO ground wire.

This could have been potentially FATAL -- wet hands, faucets, good
electrical grounds all over the kitchen.

Most likely source of this voltage is in the boiler. May I suggest you
replace the boiler, and add a 3 wire grounding line cord to the rig,
and a GFI as well.

Heya Dave.

I measured the AC and it's 0. I have a 3 wire grounding plug, but the
bloody thing is made of plastic and has only two wires connected. I'm
still trying to figure that out.

I don't suppose you know where the Paros is supposed to be grounded?

Thanks!

Most Gaggia's use a thermal fuse to protect the machine from heat damage.
Where this attaches to the boiler there is a small tab sticking up. This is
the normal(?) attachment point, but I've also seen them grounded to the
case. Either will do, but I'd highly recommend that you replace your wall
outlet with a GFI as the first order of business.

Given his current leak, plugging his machine into a GFI will likely trip the
GFI instantly, the result being he won't be able to use the machine, not
that he should be using it anyway until the source of the current leak is
found.

What?

There's someone out there who can't unplug a machine, remove the cover
screws, loosen two screws to remove the power cord from the block connector,
loosen the screw holding the power cord to the case, slide the old cord,
out, slide the new cord in, replace wires, tighten screws, connect ground
wire, replace cover, replace the screws for the top, & plug the machine back
into (hopefully) their GFI wall plug?

My 95 YO Granny could do that while blindfolded & one hand tied behind her
back. No, wait a minute; she's been blind since '98 & the stroke last year
left her without the use of her right hand. But I'll still bet she could do
it, and the most complicated task she's taken on would be deciphering a
recipe for a Betty Crocker cookbook.

Sorry about the unintentional insult, David, I certainly didn't mean to
overestimate your skills!
;-)

Everyone else though should give this a shot - playing with water under
pressure & electricity has lethal possibilities. It's no joke.

Mirek , apologies to you, and NOT meant as a criticism, but you are in

stop fooling around and get it fixed / checked out by someone who has
actually fixed one (or a hundred) before.

Hell -- send it to me and I'll check it over / fix whatever - free. you
