Wash Circuit
As the washer 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 di-
rection for 12 seconds. This is accomplished through the use of a variable frequency drive. The time of the
bath is programmable up 15 minutes per bath used.
Drain, Rinse 1 - 4, & 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 ll as above. For the Final Rinse, the Final Rinse LED will illuminate.These water temperatures are
programmable also and will ll as described above.Also the softener dispenser will ush cold water from
C2 cold water valve solenoid at beginning of nal rinse bath for 20 sec..
Extract Circuit
The Spin LED will illuminate and the washer controller PCB sends a signal to the Variable frequency drive
via the data cable at P6 to VFD RJ-11. The rotation as viewed from front during spin will be CCW except
for the 18 lb washer it will spin CW. The motor is a 3 phase 230 VAC type motor for all models .
Thermoactuator and Shake Out Circuit
The Lock Thermoactuator loses power and opens 1 1/2 minutes before the end of the cycle . 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 115VAC through the org/red wire from P17 at main relay PCB. The basket will come to a
stop from extract speed with the assistance of dynamic braking resistors wired in parallel to the variable
freqency drive. The washer will then tumble for 45 seconds to let the clothes shake loose and then stop.
End of Cycle Circuit
The machine is now stopped and does 2 things: 1. The beeper will signal for 5 seconds letting the user
know that it is the end of the cycle. 2. The micro-controlled PCB resets and display will reset when door is
opened and it is now ready to run again.
