Fill Circuit-Warm

S1, S2, and S3 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 re-

ceives 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-con-

trolled 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 Pre-

wash 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 cycle previously; we’ll use Normal Wash; the washer ﬁ lls 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 ﬂ ushes 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 ﬁ lls 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 predeter-

mined level the Pressure Switch moves switch contacts to the full position and shuts 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 con-

tact a 5 VDC reading will open.

Wash Circuit

As the washer ﬁ lls 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 12 seconds, pause, and

then reverse direction for 12 seconds. This is accomplished through the use of a variable fre-

quency drive. The time of the bath is programmable up 15 minutes per bath used.
