My elderly father has just bought a new AEG-Electrolux washer-drier. It
was delivered yesterday and I helped him get it installed and working.
While adjusting the feet with my hand between the casing and the
concrete floor I noticed a distinct tingling, until I disconnected the
machine from the mains. I thought that was odd, and wondered if the
earth connection was not quite right. But I was running late and keen
to get home, so didn't follow it up at the time, unfortunately.

This evening my father phoned me to say he got a distinct shock from the
metal barrel when unloading a new batch of clothes. Although his
faculties aren't as acute as they were, he's a retired electrician so
fully aware of the difference between a mild and a more serious electric
shock. From his description over the phone, it sounded like the latter.

The machine is in a back porch, and the mains socket has been in place
for maybe 30-40 years, so it might have a corroded earth connection -
something I'll obviously follow up as soon as I can.

Meanwhile I told him to try the machine on an extension lead so it can
be plugged into somewhere else in the adjacent kitchen, which ought to
be ok. If the leak between live and the metal casing of the machine is
really large it ought to blow a fuse or two when properly earthed.

Appliances like washing machines are clearly designed to be used when
earthed properly, but I assume they must be designed to be reasonably
safe even when accidentally used without a proper earth connection. Does
anyone know if there are rules on how much current can be allowed to
leak from live to the metal casing?

Also - even if it turns out to be badly earthed, is there a case to be
made that the machine is faulty and should be replaced by the shop if
one gets a detectable shock from it?

If the earth is broken or high impedance, the mains filter will
create a low current (up to 1.5mA) leak to the machine's case.

The fault is thus with the lack of earthing since the
machine is probably class-1 ("Must Be Earthed").

Check the earth continuity for that final circuit, check MEB
is present & correct, check supplementary bonding etc. If
the area is prone to damp, solid floor, perhaps add RCD.

Also, use new hoses not any old original (they fail eventually :-)

The shock could have been from a fault where by the ground is live and
the casing of the washer is properly earthed - just something to keep
in mind.

Now assuming the more likely shock from the case of the machine.
Machine these days are microprocessor controlled, so it will have a
filter on its mains input. The filter has some leakage to its earth
connection and if the machine lacks a proper earth, it would then be
possible to get a slight shock by touching the case and a ground.

Most likely scenario is the the socket you have plugged the washer in,
lacks an effective earth. Attend to it as a matter of urgency.

The fault is with his socket and/or house wiring.

You should not use the appliance without having the wiring fault in the
house
rectified. You could kill him by not acting.


Also - even if it turns out to be badly earthed, is there a case to be
made that the machine is faulty and should be replaced by the shop if one
gets a detectable shock from it?


Why would a shop replace a new product because a person chose to use it with
faulty and/or unsafe
sockets and/or wiring in a house?

Good advice, i have seen this so many times with old and damaged wiring.
The best was someone who had a firework display using a washing machine
and also had incredible electric shocks reaching in to a chest freezer.
It is the socket and/or wiring in the house that is faulty. It seems stupid
to
ask about changing a product but leaving faulty wiring and/or sockets!
Buy a socket tester, then get it sorted before you see the person killed.
I saw one person who had a wiring fault after he touched both taps to
put water in a sink, he was dead as the current flowed up one arm and down
the other. Others I have seen with some nasty burns, one person even
jumped backwards and hit a worktop with a knife on it! Cuts and burns
are easier to treat - bringing someone back to life is a touch more
difficult.

I have seen some bad wiring faults in my time but they have caused no
deaths.

I did see a worktop with a knife on it last week. I forgot to inform the
emergency services as I was busy washing up at the time.

Well as I said in my original posting, obviously I suspect the house
wiring and have told him to use it only when plugged into a different
socket until that one has been checked and fixed.

I was surprised about the leakage from mains to earth in the appliance,
but others suggested that modern appliances have a mains filter which
has that effect. Thanks - that's news to me, though maybe I should have
guessed.

I suppose one could think of the effects of that leakage as a useful
warning: if you plug the washing machine into a socket with a poor earth
the shocks you get warn you that something is wrong. The old one, now
defunct, didn't do that.

Just asked my paramedic daughter about that. In 4 years of frontline duty
she has attended just 2 cases of electric shock. One was a bloke who was
woken by a mains smoke alarm. To silence it, he stood on some metal kitchen
steps (barefoot) and used a pair of metal kitchen scissors to cut the cable.
He also managed to stab himself in the leg - twice - whilst falling off the
steps :-)

Thats a brain fault, not an electrical fault. The other one was faulty
wiring.

The original poster did say that the wiring had been in place for
30-40 years (you quoted the text, above). So it is quite likely that
no RCD was fitted.

GMM explained :

The leakage has to be of a sufficient value, before the RCD will trip.
Filters, though of sufficient leakage to provide a mild shock, do not
provide enough leakage to trip the RCD. The exception is when a number
of the filters are used on the same circuit, where the leakage adds up
and can be enough to cause a trip, or cause nuisance tripping.

Very interesting - it sounds like there's a bit of a tension between

My long dead mother did something similar in the early stages of
Alzheimer's. She couldn't remember how to stop her electric alarm clock
from buzzing so cut the flex with scissors. Luckily only suffered a minor
burn. The alarm was on one of those pukka clock sockets which need a nut
removed before they can be unplugged.
