Fill Circuit-Warm Continued...
Now a cycle must be selected with the Selector Switch. We’ll use Normal Wash. The washer fills the tub
through the back of the machine with either one or both the C1 Cold and H1 Hot Water Valves. At the
beginning of the cycle, the detergent dispenser flushes the detergent into the tub. This is accomplished
with the Wash Dispenser Contact in the Main Timer. 120VAC travels through the closed Wash dispenser
Contact and is supplied to the H2 Hot Water Valve Solenoid by the red/orange wire. As the washer fills
with water, the Wash Basket will tumble one direction for 19 seconds, pause, and then reverse direc-
tion for 19 seconds. 120VAC travels from the Wash Water Timer Contact to the Heavy Duty Contact in
the Selector Switch via the white/black wire. 120VAC goes through the closed Heavy Duty Contact in the
Selector Switch and energizes the C1 Cold Water Valve Solenoid via the white/orange wire. 120VAC also
travels to the closed Wool/Delicate Contact in the Selector Switch. This closed contact provides power to
the H1 Hot Water Valve Solenoid via the red/yellow wire. When the water reaches the predetermined level
the Pressure Switch moves to the full position and opens the neutral side of the line to the Water Valves.
This shuts the Water Valves off. The neutral for the Water Valves & Main Timer Motor is provided through
the Pressure Switch. The Main Timer is stopped until the Pressure Switch provides neutral when full level
is reached. Neutral for the Main Timer Motor during drain and spin is provided through the Delay Fill Timer
Contact.

Wash Circuit
As the washer fills the tub through the back of the machine with either one or both the C1 Cold and H1
Hot Water Valves, the Wash Basket will tumble one direction for 19 seconds, pause, and then reverse
direction for 19 seconds. This is accomplished through the use of a Reversing Timer. 120VAC is supplied to
the Reversing Timer Motor on the blue/black wire from the Wash Motor Timer Contact in the Main Timer
and 120VAC is supplied to the R1 Run Relay any time the door is locked. This R1 Relay closes & provides
24VDC thru the Reversing Timer Wash Micro Switches. The Reversing Timer will alternately open and close
the two Wash Micro Switches and provide 24VDC to the FW (forward) or RV (reverse) terminals on the
Variable Frequency Drive.
As discussed in Start and Fill, the Lock Thermoactuator, Drain Valve, On Light, and Main Timer Motor (ex-
cept in fill) are all operating throughout the Wash Cycle.
Drain, Rinse 1 & 2, and Final Rinse Circuit
The Drain Contact on the Main Timer opens. removing power to the Drain Valve. The normally-open
spring-loaded Drain Valve opens and empties the tub.
For Rinse 1 & 2, the Rinse Light Contact in the Main Timer closes and provides 120VAC to the Rinse Light.
The Rinse Water Contact in the Main Timer also closes and provides 120VAC to the C1 Cold Water Sole-
noid. The tub will fill until the predetermined level is achieved at which time the.Pressure Switch Contact
will open the neutral side of the line shutting off the C1 Cold Water Solenoid. When the tub is full, the
pressure switch also closes a neutral circuit to the M1 Timer Motor and to the orange/yellow wire on the
Coin Accumulator Board. This allows the Main Timer to advance only after the tub is full and stalls the time
count down on the Coin Accumulator Board during fills.
For the Final Rinse, the. Final Rinse Light Contact in the Main Timer closes and provides 120VAC to the
Final Rinse Light. Rinse water is the same as in Rinses above.
As discussed in Start and Fill, the Lock Thermoactuator, Drain Valve, On Light, and Main Timer Motor (ex-
cept in fill) are all operating throughout the Wash Cycle.
Intermediate Extract Circuit
The Wash Contact remains closed and provides 24VDC to the closed Clockwise Micro Switch on the
Reversing Timer. 24VDC is then fed to the Counter Clockwise Micro Switch via a jumper wire..120VAC is
then sent to the Delay Spin Micro Switch. The Delay Spin Micro Switch provides 120VAC to the Spin Motor
Contact in the Main Timer on the blue/white wire. The Spin Motor Contact is closed for spin and the volt-
age continues on to the R2 Spin Motor Relay Coil on the red/black wire. With 120VAC to the R2 Spin Motor
Relay Coil two things happen. 120VAC is now provided from the orange wire directly to the Relay eliminat-
ing the Reversing Timer and the Micro Switches from the circuit.
The second thing that happens when the R2 Relay is closed is that 24VDC is provided from the DCM ter-
minal of the Variable Frequency Drive through the R1 Run Relay through the R2 Spin Relay to terminals Ml
1 & Ml3 on the Drive and the washer spins at intermediate speed.
Final Extract Circuit
Same as Intermediate Extract but adds the R3 Extract Relay. The Main Timer provides 120VAC to the
Extract Relay Coil. When this relay closes it provides 24VDC to the Ml2 terminal on the Variable Frequency
Drive. This means that all 3 terminals Ml1, Ml2 & Ml3 are powered for high spin.
Unlock Thermoactuator and Shake Out Circuit
The Lock Thermoactuator Contact in the Main Timer opens 1 1/2 minutes before the end of the cycle
removing the neutral to the Thermoactuator. This allows the Thermoactuator time to retract by the end of
the cycle.
To insure that the Lock Thermoactuator has retracted by the end of the cycle, 1 minute prior to the end
of the cycle, the Unlock Thermoactuator is powered with 120VAC through the Unlock Thermoactuator
Contact in the Main Timer.
The Spin Motor Contact in the Main Timer opens, stopping voltage to the R2 Spin Motor Relay & the mo-
tor. The basket will coast to a stop. The Wash Motor Contact in the Main Timer closes providing power to
the Reversing Timer once again (discussed in Wash Cycle). The washer will tumble for approximately 30
seconds to let the clothes shake loose and then stop.
End of Cycle Circuit
The On-Off Contact in the Main Timer opens removing power to the Door Lock Switches and Contactors.
The machine is now stopped. The Start Contact on the Main Timer is closed providing 120VAC to the Coin
Accumulator Board on the white/green wire.
The End Of Cycle Contact in the Main Timer is closed sending a 120VAC signal to the Coin Accumulator
Board on the white/yellow wire telling it that the cycle is over. This does 2 things:
1. The beeper will signal for 3 seconds letting the user know that it is the end of the cycle.
2. It resets the Coin Accumulator Board and it is now ready to count coins again.
