My Mira Sport 9.8 is literally days from the end of the 2 year guarantee,
and has developed an intermittent fault.
Two days ago, when I tried to use the shower, there was only a dribble of
water coming from the handset, and the low flow light (LFL) was illuminated.
I tried switching the shower off & on a few times, but the problem remained.
I took the shower handset off, and cleaned it (even though it wasn't visibly
dirty), connected it back up, and the shower worked normally. Initially, I
thought that might have solved the problem, but wondered why the LFL would
come on if the problem lay with the handset? (I have since noticed that if
this was the problem, according to the manual, the LFL should be off)
After having a shower, I tried switching the shower on & off a few times -
sometimes it worked normally, at other times, the problem recurred.
The following morning, on first attempt, the shower worked normally. Last
night, however, the problem occurred when first tried, and it took a few
on/off cycles to get it working. This morning, it worked normally on first
attempt and for the next few on/off cycles, then started the same problem,
I contacted Mira, and after asking if I had tried cleaning the handset, had
any problems with water pressure (I haven't noticed any change in the cold
taps, toilet, operation of washing machine etc.), they said they would
arrange for a service engineer to visit, but if no fault was found, a call
out fee of £65 would be charged. Similarly, if the problem lay with the
inlet filter, the call out charge would also apply.
I now appear to be in a 'catch 22' situation - the manual clearly states
that only a 'competent tradesperson' should remove the front cover, clean
the inlet filter etc., so I can't try this myself, but if I call a local
plumber/service engineer, they will (not unreasonably) charge me, but why
should I do this when the shower is still under guarantee?
Since the call to Mira, I have noticed that when the problem occurs, and the
cold tap in the bathroom is turned on 'normally', the shower then springs
into life and starts flowing correctly; but if the tap is turned on
slowly/gradually, it doesn't seem to have an effect. Also, when the shower
is switched off, the flow stops after about one second, rather than running
for few seconds, as it used to/is supposed to.
Not sure if this is likely to be relevant, but I had a new washing machine
installed about a month ago (cold fill only) - would I be correct in
thinking that only the 'tap' that the machine is connected to would have
been turned off, not the main stopcock? (As mentioned, the shower problem
has only just occurred.)
Any suggestions as to what the problem is most likely to be, and what I
should do with regard to the Mira engineer, considering the intermittent
nature of the problem, the possibility of the problem being down to the
inlet filter, the threat of a large call out charge etc.?
