Dropped in to see my mum yesterday and she said the shower was playing up.
The symptoms are with dial #1 on hot (one step down from high) and dial #2
on 7 (of 9), the pump runs and the water gets hot. However, the temperature
varies noticeably and after running for say five minutes, the water goes
cold and the pressure drops. My mum has also said that it has stopped
completely a few times.

Diagnosis?

I assume a shower like this consists of a heater, a heat exchanger, a flow
control valve, a thermostat and a pump.

Cheers, Rob.

How old is it?

We've had a couple of Mira Sports (last house and current one) and they've
both been very good. Neither have failed yet, although the current one at
times is now louder then normal.

Electric showers certainly don't last for ever. If the shower is quite old
and out of warranty then you may as well just buy another one in my book.
Ours was about £140.

How old is it?

Not that old - I fitted it about five years ago.

Might end up doing that - just hope the inlet pipe are in the same place!

Hi,

As Mira are a 'premium' brand I should expect they'll have a well
staffed product support line who can help pinpoint the fault and
advise how to get it fixed.

It might just be that the inlet strainers or the thermostatic valve
are getting blocked by scale or debris and the pump overheats and cuts
out.

Or there is a blockage elsewhere in the hot water pipe and the pump
cuts out on under pressure.

cheers,
Pete.

The problem is that any electric shower manufacturer will advise that under
no circumstances should anyone other then a properly qualified service
engineer open one up.

That's when the cost effectiveness of a repair over a replacement will then
come into question.

.... and if it's anything like my long-ago-ripped-out Triton T200RE (the
Worst Product I Have Ever Bought) the plastic will all start crumbling away
making replacing bits of it impossible. After several repairs I ended up
having to fork out for a whole replacement main unit as they didn't make the
"back panel" available as a separate part and that was the main bit that had
crumbled away. Seemed to be made of the kind of plastic that cracks up after
a couple of years of mild heat!

Anyway it's long gone now (removed and smashed to pieces) and replaced with
two showers running off my big combi. Far better.

BTW did I mention that the Triton was the Worst Product I Have Ever Bought?

Simon.
