I've never had a problem with water in the electrics on any bike I've owned.. at least water from riding in the rain, and I've gone through some serious storms over the years. However, I have known people who whacked their electrics after washing, which in that case, was a result of water being squirted where it would not normally have gone under 'normal' circumstances
