As a fellow Perth resident..... no coffee machine should EVER be given a dose of Perth water (unless softened)..... Perth water has so much calcium in it it is not funny!!! (5 times more than our Eastern States cousins!)....
If using say a Brita jug (the least you should use).... you will need to change the filter element almost weekly over here..... the same with an "in tank" softener in the machine.....
I suspect your steam thermoblock is blocked with calcium deposits..... and will require a repair or possibly a replacement.
You can try to descale a themoblock... but it is very difficult as it is more prone to blocking as it is only a thin pipe.... and all that leaves is steam.... the deposits tend to remain (dispensing hot water with descaler may help before it gets totally blocked)
And, yes a boiler machine (like the Silvia) is a better proposition here. Scale will still form in the boiler but is far more easily removed (and does less damage).
