Sometimes the internet restores my faith in humanity, and today was one of those days. I stumbled across a thread where someone had posted about their absolutely revolting dishwasher filter – we’re talking proper grim stuff that looked like it belonged in a horror movie. But what really got my attention wasn’t the gross factor (though my teenage daughter would definitely have gagged), it was what happened next.

A professional appliance installer saw the post and took time out of their day to create an entirely new thread, complete with diagrams, explaining a plumbing issue that could be causing similar problems for loads of people. No agenda, no selling anything – just genuine helpfulness. It’s the kind of thing that makes you realise the internet isn’t entirely broken.
