Firstly thanks for the advice/comments

How sure are you that the "identical" replacement had the same power
rating as the previous one? I strongly suspect your replacement is
more powerful, as a fused one is likely to be at 30A, giving a maximum
of 7.2kW. Of course, it is possible to get bigger fuses, but they
aren't that common. Don't go fitting a bigger fuse unless the cable is
found to be OK for the larger current.

I had the Aquatronic 8500 for a couple of years, it had blown the fuse
once before and was cutting out all the time. I had the manual left from
the previous owner and checked inside the housing for the rating. I
wanted somthing I could replace myself, so bought the Aquatronic 2 from
Wickes - for £60 or so with 2 years warranty. Everything was in the same
place i.e water/cables etc so was a easy swap.

I was concious of the cable and looked along it length I can see (in the
loft) any size mention, nothing written so measuring the size looked OK.


Should I be concerned about this?. I can easily replace the fuse and
hopefully catridge, but it has scortched some of the bit the fuse
plugs into - can this be replaced.

I went to my local electrical place an bought a 40amp Wylex Catridge (in
the manual for the shower it says use a 45A an 6mm. I also got a
'cutting' of 6mm cable so I could compare. Ive taken off the shower cover
and unscrewed the cable and measured it against, what I got given. They
both look the same size, with multiple strands for the core and measure
around 5mm with my ruler.

So I pretty confident the cable is good and the correct size.


Yes, but fuse boxes always seem to do this. After a few blows, they
look like melted Mozzarella on a pizza. Consider replacing your
consumer unit with a modern one, with RCD and MCB protection.

I seem to remember that the fuse did seem quite loose and maybe that
didn't help.
