Thank you all for the replies,

I've disassembled the electric shower, as I suspected the connector
elbow looks like cracked, and the position of the crack corresponds
to the sprinkle pattern. I've ordered the spare part from he

I'll try replacing it. LS-X doesn't look like viable in this
situation, given 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't understand how the electrical part of the shower is made safe
against water spillage.

The RCD imho isn't safe enough in a shower, as it switches only after
a shock is taken. Ok it avoids prolonged electrocution, but still the
electricity available at home is a lot and even a quick shock with
all these ampere seems to me very painful and potentially deadly.

That's why I asked here if electric showers are something people can
fix DIY 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 the conventional electric oven, I'm starting to feel like a pro in
fixing appliances.

I'll keep you posted.

thanks,

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
variety.

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.
