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
The motor cannot be reversed instantly. It needs a brief pause between switching directions, or else it may get damaged. For this purpose, another spin direction control timer (IC2) is employed. It is realised with an IC 555. This timer gives an alternate ‘on’ and ‘off’ time duration of 10 seconds and 3 seconds, respectively. So after every l0 seconds of running (either in clockwise or anticlock-wise direction), the motor stops for a brief duration of 3 seconds. The values of R3 and R4 are calculated accordingly.
