Hi, That's exactly what they look like! I can't think of a better way to describe it.
I haven't found a manual at all, but a friend suggested that I try using dishwasher salt and rinse aid. I bought some at the weekend and put some in yesterday. Both packets say to refer to the manufacturer's instructions which I don't have so I'm just guessing really. I'll let you know if I have any luck.
