Downgraded from a 9.5Kw shower to an 8.5kw one. Need to change wires/fuse/switch as well?

No, fuse generally protects the cable. Smoke probably means high resistance connections which won't blow the fuse unless the cable shorts, which it did once but maybe not again. Not sure what you're getting at.

I have seen the results of this once. A guy called me to ask what to do. He was having a shower and the power shower was on fire. You can imagine my response. I later discovered cable burnt out inside the power shower. Someone had fitted a 'cheaper' lower capacity power shower and left the higher capacity fuse in place. Remedy: rip out and back to gravity fed shower.

The only way you could know the cables are extremely hard to bend is you have changed the switch your self. That could be the problem.

#10 also says "I will change the shower myself"!!

Yeh and #13 says that could be the problem.
