Is the switch double pole, double throw? How did you get to do what was needed?
Steve it’s a single pole double throw switch. Since I didn't have a wiring diagram for this Cissel water temp switch/timer I had to do some electrical tracing to figure this out. Turns out it was pretty easy, here is how it works.
The fill circuit has two lines, the black line (connected from the timer to the water temp switch and the blue line connected directly from the timer into the cold water valve.
For wash, the timer sends 120 volts of current into black line only. The black line connects into my new toggle switch.
-When the switch is in the "up" position the switch transfers the electricity to the red wire which is connected directly to the hot solenoid, this makes the washer fill will hot water.
-When the switch is in the "down" position the switch transfers the electricity to the blue wire which is connected directly to the cold solenoid, this makes the washer fill will cold water.
-When the switch is in the "middle" position the switch transfers the electricity to the both the red and blue wires which energizes both solenoids so the hot and cold water is mixed into a warm fill.
Now for the Rinse Cycle:
The timer energizes the black wire to the toggleswitch just like for the wash cycle, but the difference here is the timer also energizes the blue wire which is connected directly to the cold solenoid. Since the timer is providing power to the cold solenoid directly the cold solenoid is always on during rinse fills. But the timer also energizes the black line so if the switch is in the "up" or "middle" the hot solenoid will also be turned on during the rinse fill. If the switch is in the lower position its only sending power to the cold line (which already is getting power directly from the timer) and makes for a cold rinse.
Clear as Mud?
