We stopped using our electric shower at home because it started leaking water from the wall mounted part of it.
After opening it I've found that there's a leak somewhere, not far from the electric connections.
I see the water sprinkling in the circled area in this image:
The shower is a Galaxy Aqua 3000 10.5Kw.
Do you think it's something that could be fixed? or should we look for a new electric shower all together?
My first thought which sounds condescending but not meant to be is "if
you have to ask then you possibly ought not to try to repair"
However trying to be constructive....
Depends if you can get the parts? could be a simple seal that has failed
- likely to be a generic O ring or part of the moulded plastic bit has
split and you will need the bespoke part.
I found the original spares here, I will try replacing the N. 14, which seems to me the broken part.
You are right, it might well be the gasket or the orings, I'll try replacing them all.
I've never repaired an electric shower, what scares me is all that water so close to the electricity. That looks pretty dangerous to me. Though I've seen several electric showers working similarly, and I don't understand how these can be considered safe.
Is there any security mechanisms in the electric showers that I might not be aware of?

The casework it all insulating - even the chrome bits are usually just
chromed plastic. The metal pipe (if it has one and its real metal) tends
to be floating (electrically).
The conduction path to earth in the shower enclosure is probably not as
good as one might expect (insulating tray in most cases). Any extraneous
metalwork that could bring an earth potential into the room (taps, CH
pipes etc) will (if done correctly) be EQ bonded with the shower, or all
circuits protected by a RCD.
So the worst case is usually an insulation fault in the boiler chamber /
element could result in "live" water. Again RCD/ Conventional earthing
will disconnect the supply in short order in that case. Coupled with the
reality that clean water is not actually a very good conductor in the
I would suggest the biggest risk from most electrical showers (if you
exclude expiring from old age waiting for a good one) is a fire risk
from the cabling, since the very high currents involved can generate
lots of heat at any connection points.
That would make asking a question, and this group obsolete.
I would make doubly sure where the leak is and disassemble. Like Bob, I
would suggest a new O-ring may be the fix you require.
Not sure if Fernox LS-X would help in sealing the joint when reassembling?
Not quite true - some jobs have particular hazards associated with them
and it is very difficult to judge when offering advice if the questioner
has general awareness or is largely fuelled by enthusiasm rather than skill.
After a few years of reading this group one can begin recognise some our
resident A-holes relatively easily! lol
I'm not suggesting the OP is one of those incidentally!
Thank you all for the replies,
I've disassembled the electric shower, as I suspected the connector elbow l
ooks like cracked, and the position of the crack corresponds to the sprinkl
e pattern. I've ordered the spare part from here:
I'll try replacing it. LS-X doesn't look like viable in this situation, giv
en the type of damage and its position.
The o-rings look in good shape, so I think I'll be keeping the current ones
, if I don't get new ones with the spare.
As suggested by Bob M. I see this work as a potentially hazardous, as I don

The RCD imho isn't safe enough in a shower, as it switches only after a sho
ck is taken. Ok it avoids prolonged electrocution, but still the electricit
y available at home is a lot and even a quick shock with all these ampere s

That's why I asked here if electric showers are something people can fix DI
Y or if it's always better to refer to an expert.
I'm somehow experienced in repairing electrical parts, and as a kid I took
enough shocks to be extremely careful in these matters.
From the answers I am under the impression that people do fix these things,
so I will give it a try.
After replacing the microwave grilling components, and the thermostat on th
e conventional electric oven, I'm starting to feel like a pro in fixing app
liances. :) :)
I'll keep you posted.

4 is demonstrated by the use of crude electrode showers, where people bang
a nail into a hose, connect it to live and shower under it.

much safer to diy imho - long as you're capable enough

If we never hear from you again we'll know why :)
I would recommend against top posting as it offends a number here!
Like any hazardous situation, care and some understanding is required.
Personally I would only ever use one hand, and keep the other well away
from anything metallic in any situation that may possibly be live, in
the belief that it would reduce any electrical path across/through the body.
For info, the earth sleeving is black and not the usual green/yellow
I'm afraid the RCD is all you have for protection. 10mA ones are rare
if you want greater protection.
Despite this, there is an earth wire going to the shower heater.
Although the heater body may be plastic, it's likely the heating element
sheath is earthed, so the water being emitted from the shower is always
going to be close to earth potential.
Well... heating elements split open at some point, passing power directly t
hrough the water. Hopefully there is an earthed collar around the water out
put. But even if the showerhead were fully live, standing under the stream
would seldom result in shock, so theyre not as dangerous as might be imagin
Top posting messes with the record of the discussion. Its not usually good
Good advice when poking about in the back of live TVs etc, but it ought
not be too difficult to prove a shower circuit is de-energised before
working on it!
Indeed, and the cable clamp not on the right bit of the cable...
That is far from true. Plenty of showers out there without RCDs at all!
It does not really make it any safer - remember RCDs do *not* limit the
magnitude of a shock - only its duration. So in a shock situation which
is going to pass 100mA through you, the trip rating of the RCD will have
no effect on the severity of the shock.
Which under fault conditions could be a couple of hundred volts ;-)
(Although not for long)
Just make sure the water has broken into droplets by the time it hits you.
Interesting thought - the water is live due to a fault but you're
showering unaware of this because the stream is broken into droplets.
You take the plastic shower head down in order to give the goolies a
I've already received the spare part (wow that was quick). I assembled it in the shower and..... drum roll.
no leak any more... it works.
Thanks for the very useful help.
