Hi everybody! My Arduino project is to replace the mechanical timer on a very common clothes washer: The Whirlpool Direct Drive (A.K.A. "Design 2000").
These appliances are very simple: Only 2 coils for the water valve (one for cold and another for hot water), a pressure switch, a water temperature switch, the timer and last but not least the reversible 1/2 Horsepower motor, wich spins at 1725 RPM and draws about 10A. I think the motor is the most important part of the washer.
Here are some pictures of the electrical system of the washer: This is the inside of the top control panel.From L to R: Water temp switch, Water level/Pressure switch,motor capacitor and timer
This is the pressure switch, note the air hose and 3 wires.
From this side you can see the other part of the pressure switch and the water temperature sw.
This is the motor harness plug
The motor Itself
I forgot wich pic indicates the motor rotation :sweat_smile:
Oh! This is the schematic
Tomorrow I'll buy various relays for the motor and water inlet valve.
Any questions or advice?
Any help would be greatly appreciated (Sorry for my Engrish :()
