Why no wiring diagrams repair manuals and circuit diagrams for appliances? Wiring-diagram Unfortunately, if you are looking for a circuit diagram, or wiring schematic or even a repair manual for your washing machine, dishwasher, tumble dryer or cooker etc. the bad news is you could be embarking on a frustrating and fruitless journey because they are not officially available. (if you are only looking for a user manual try here instruction books and user manuals )
Washing machine pressure switches directly control the hot and cold water inlet solenoids and so are rated for quite high currents - 15A at 230V AC is typical. So for low-voltage DC applications, the switches can certainly cope with (say) 5A. This means that, for most loads, a relay won't be needed.
