Fill Circuit-Warm
S1, S2, S3 and S5 Door Switches are now closed . The green On LED and the Door Lock Solenoid
(discussed in Start Circuit) will remain on throughout the cycle. The Lock Thermoactuator receives 115VAC on
orange/blue from P17 on main relay PCB and will alternate open and closed keeping the Lock
Thermoactuator activated until 1 1/2 minutes before the end of the cycle. At this point the contact opens and
removes power to the Lock Thermoactuator.The micro-controlled PCB also sends a signal to the main relay
PCB and out through P17. The brown/yellow wire from P17 at main relay PCB supplies 115VAC to Drain
valve which closes the valve. The reversing operation which will alternately provide the direction of tumble
for the wash basket will be given commands to the VFD through the data cables at P6 micro-controlled PCB.
The Prewash or Wash LED will illuminate at this time powered through the white wires from the micro-control
PCB P3 to LED printed circuit board.
Now with a temperature cycle previously selected; we'll use Normal Wash as an example; 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 wash cycle bath only after a 90 sec. delay, the detergent dispenser flushes the
detergent into the tub for 20 sec.. This is accomplished when 120VAC travels through the red/orange wire to
the H2 Hot Water Valve Solenoid. As the washer fills with water, the Wash Basket will tumble one direction
for 12 seconds, pause, and then reverse direction for 12 seconds. 120VAC goes through the P19 connection
of main relay PCB on wht/brn to the C1 cold water valve and the red/yellow wire to the H1 hot water valve if
programmed. When the water reaches the predetermined level the Pressure Switch moves switch contacts
to the full position and shuts neutral voltage off to the both water valves.Between red wire from P5 micro-
controlled PCB on pressure switch contact and yellow and orange wire from P5 micro-controlled PCB at
other pressure switch contact a 5 VDC reading will open.
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, pause4 seconds, and then reverse
direction for 19 seconds. This is accomplished through the use of a variable frequency drive and a reverseing
timer. The time of the bath is programmable up 15 minutes per bath used.
Drain, Rinse 1 & 2, & Final Rinse Circuit
When the bath ends the micro-controller PCB removes 115 VAC power from brn/yel coming from main relay
PCB at P17 to the Drain Valve. The normally-open spring-loaded Drain Valve opens and empties the tub.
For Rinse 1 & 2, the Rinse LED will illuminate.The rinse water temperatures are programmable and will fill as
above.
For the Final Rinse, the Final Rinse LED will illuminate.These water temperatures are programmable also and
will fill as described above.Also the softener dispenser will flush cold water from C2 cold water valve solenoid
at beginning of final rinse bath for 20 sec.
