Line switch circuit
The line switch, formed by the contacts between terminals T1 and T2 of the timer, controls power to the washer. The
contacts of the line switch are controlled by pulling the timer knob out to close and pushing the timer knob in to
open.
Fill circuit
At the start of the
Wash Cycle,
power passes through terminals T1 and T2 (the line switch) of the timer to terminal
T16 of the timer. During the
Fill Cycle,
T16 is connected to terminal T17 of the timer. Terminal T17 is connected
internally in the timer to terminal T10 of the timer. Terminal T10 is connected to terminal 2 of the pressure switch.
When the tub does not have water in it, terminal 2 of the pressure switch is closed to terminal 1 of the pressure
switch. From terminal 1 of the pressure switch, power is applied to terminal T23 of the timer. Terminal T23 is
closed to terminal T22 of the timer. Terminal T22 provides two outputs, one to terminal FF of the temp switch and
the other to terminal F of the temp switch through terminal T19 of the timer.
During the wash cycle when temp switch is set to:
Hot /Cold
Contacts F to H of the temp switch are closed and power is applied to the hot solenoid.
Warm / Cold
Contacts F to H and FF to C of the temp switch are closed and power is applied to both
the hot and cold solenoids.
Cold / Cold
Contacts FF to C of the temp switch are closed and power is applied to the cold solenoid.
Warm / Warm
Contacts FF to H and FF to C of the temp switch are closed and power is applied to both
the hot and cold solenoids.
Reg Cold / Cold
Contacts FF to C and F to D of the temp switch are closed, FF to C applies power to the
cold solenoid and F to D applies power to terminal 5 of the automatic temperature control.
The hot solenoid is then cycled as needed by power from terminal 4 of the automatic
temperature control to raise the incoming water temperature to around 70
°
F.
Reg Warm / Cold
Contacts F to H and F to D of the temp switch are closed, F to H applies power to the hot
solenoid and F to D applies power to terminal 5 of the automatic temperature control. The
cold solenoid is then cycled, as needed, by power from terminal 6 of the automatic
temperature control to lower the incoming water temperature to around 90
°
F.
Reg Warm / Warm
Contacts FF to H and F to D of the temp switch are closed, FF to H applies power to the
hot solenoid and F to D applies power to terminal 5 of the automatic temperature control.
The cold solenoid is then cycled, as needed, by power from terminal 6 of the automatic
temperature control to lower the incoming water temperature to around 90
°
F.
