Washing Machine Diagram / August 19, 2018 / Samara Dowell.
The above mentioned signs may or may not indicate a faulty heating element. The reasons for the above noted symptoms might be some thing else. The sure way to confirm a faulty heater is using the ohmmeter. It is a device for checking electrical values like resistance between 2 conductive appliances. To test if an element is working or not a professional connects neutral wires to the related connectors on the element and verify it for a positive reading.
(Note that if the washing machine has digital controls, rather than a mechanical switch, it almost certainly uses an electronic variable pressure sensor to detect the water level. These three-wire sensors are easy to interface, but we'll leave them for another time).
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.
