I'd check those spade terminals in the shower for tightness.
If in doubt I usually slide 'em off, squeeze 'em ever so slightly, and shove 'em back on real tight.

They're probably mentioned and required in the Manufacturers Information of most, if not all showers.

alot of customers believe the isolation switch is to turn the shower off the second you finish using it.

I'm still trying to figure out why instantaneous electric showers are so popular in the first place. If for a retrofit application where only a cold feed is easily available I can see the attraction, but when building or refurbishing a bathroom from scratch, I can't see why anyone would want to use one in preference to plumbing in a good mixer shower from the main hot-water system.
And from the electrical and wiring regs. point of view, I find it incredible that some of the people who can get rather bent out of shape over a socket in a bathroom, or the precise location or need for a shower isolator, don't bat an eyelid at putting 240V actually inside the shower cubicle behind just a flimsy plastic cover.
Because the plastic cover is not flimsy, (unless you buy a cheap import from down the pub), and designed in a manner which, when installed correctly, prevents the ingress of moisture.
Hence, one of the requirements for it being notifiable. It MUST be installed correctly.

There are a lot of people that don't want to have a cylinder full of hot water, either because of the standing losses or simply because they don't use any hot water other than for showering. Dishwashers, washing machines etc. all run from cold these days...
Come on BAS.....
134.1.1, if, and it probably is, stated in the Manufacturers Instructions.
A few examples:
Triton T80Z - Item 6, page 5
Gainsborough showers - 4.2.12, page 5
Mira Advance - Item 2.3, page 11
Ah - OK - I wasn't thinking of 134.1.1, I was thinking of the Chapter 53 regulations on switching.
It does make you wonder why the manufacturers are selling equipment which they do not believe to be safe left with the power permanently connected to it.

I was speaking in a rather general way, that it seems odd how so many people seem to throw their hands up in horror at the idea of fitting a regular socket in a bathroom for, say, a hair dryer, yet seem perfectly happy to have 240V in a unit inside the shower cubicle - Whatever the strength of the plastic cover.
Even properly installed units get condensation inside, and in the event of a leak, the pressure involved can end up spraying water all over the wiring with leakage through the damp to the outside of the unit. The wiring regulations in many other places simply would never allow such a thing.
How many homes don't have some other form of hot-water system these days to provide hot water for the kitchen sink, lavatory basin, and so on? Many of the newer "combi" units don't maintain a big cylinder full of hot water all the time but heat pretty much on demand. Yet still the instant electric showers seem to be popular.
As I said, I can see some cases where people might find them beneficial, but I don't understand why they've become so popular even in cases where plenty of hot water is already available, given their drawbacks.
Heres the thing. The combi boiler, whilst being cheaper per kw to run, is very wasteful compared to the shower can.
Your heating is off, the boiler is stone cold. How long do you have to wait after turning on the hot water tap, before the hot water comes through? Its certainly not "instantaneous". A good minute for us. So while the boiler is burning 24kw for a minute, you're wasting a good few litres of water.
And what happens to that 24kilowatt-minute of heat you've just wasted? Its pumped round the radiators, where its not needed (or the heating would be on!)
The issue is worsened with automatic appliances such as washers, which take in a set volume of water - all the boiler ends up doing is heating the pipes and the w/m fills with cold!
An instant electric shower is convenient, efficient and quick.
Triton make an electric shower that sits in the loft with a long pipe and low voltage control wire to the cubicle.
