Replacement for Combimate

[stonedagain]

Because the water in my area is quite hard,I currently have a Combimate fitted. Since it was fitted 6 years ago, I keep having promlems with mould forming inside my washing machine. Because has only happened since the Combimate was fitted, I suspect it has something to do with the chemical which the balls are made from. Also, after reading this thread:http://www.ukplumbersforums.co.uk/central-heating-forum/6185-combimate.html#post34841 I have decided to replace it with something like one of the electrical impulse devices. Can anyone advise me on which device to purchase, or any other alternatives?
Thanks in advance.
