I read the article but no mention of those small stones. I always use Daz which as a blue compound in it and this same colour was mixed in the stones. Fortunately my AEG pump's impeller is in a separate compartment to where the stones were otherwise the pump's motor would probably have burnt out. Anyway I shall be doing regular maintenance washes from now on.

Well I've never had kidney stones but I think my washing machine might have. These stones were as big as gravel and were blocking the pump. Were they formed by detergent or hard water, or a combination? They were whitish blue in colour. Anybody come across these before, if so what were they?
