If your washing machine blows a fuse or circuit breaker within a few minutes of turning it on, this could be many things and would need further testing but one of the things that could be causing the fuse to blow is a faulty water heater element.If your wash is not coming out as clean as it used to, this again could be a indicator of a faulty element as the clothes could be washing in cold water.
Exceptions. I’m talking about the UK. It seems that there are plenty of schematic’s and wiring diagrams available for American appliances on USA or Canadian repair sites, but not so much for the UK. Some washing machines and other appliances have been known to have a wiring schematic under the lid. I know Miele and a few other quality appliance manufacturers used to place a basic wiring schematic on top of the soap dispenser or underneath the lid. This does not happen on most washing machines though, especially the cheaper ones and they are often very basic
