A friend knows a woman in America, they visit each other several times a year. Yesterday she phoned to tell him her tumble drier had stopped working and what could she do about it. Apparently, like much in America it was huge and an unfamiliar make to him. But the conversation went like this. "What's the make and model number." "How do I find the model number?" "Open the door, there'll be a plate somewhere, take a photo and send it to me." Which she did. "What is the fault code it's showing?" She checked and told him. While she was talking about other stuff he found the instruction book on the internet and looked up the fault code and the instructions on how to fix it. It had tripped out and just needed re-setting, she'd probably put too much in it. "Right.. press the top and bottom buttons at the same time until the code goes out." There was silence for a bit and then she said "It's working! How did you do that!"
Google saved her a lot of money as she didn't have to call out an engineer to fix the problem. Isn't the internet great?
Haha, oh, dear, sorry! I must admit I used that trick once when my neighbour called and told me she had somehow managed to turn her screen sideways, and if I could please help her turn it back? (Her trust in me is sadly misplaced.) I said I'd be right there, looked up what I had to do, went over and fixed it. She confessed she had gotten angry and slammed her fists on the keyboard. She won't do that again since she hates asking me for help.
The advice on YouTube isn't always the best. After fixing the blocked pump on the washing machine, doing it the same way I watched an engineer do it a few years ago, I went on YouTube to see if there was an easier way and found this which seemed a bit drastic.
