A few weeks ago I began having problems with my electricity. The switch kept tripping and we had no idea why. After a few times, the fuse in an extension cable in the kitchen blew. Our landlord is an electrician and we asked him to take a look. He thought our socket might be overloaded, so he rearranged some of our plugs so that they were more evenly spread.
The switch kept tripping and the fuse blew a few more times. We began to realise that it was always when the washing machine was on. The machine seemed to be working fine, so we tried running it without any other appliances on. Sometimes it was fine, but sometimes it tripped the switch or blew a fuse.
