Level Achieved / Stage Completion / Drain
When the water level in the basket reaches the preset level pressure, the switch moves it's switch con-
tacts to the full or closed position. This causes the main control PCB to signal the relay PCB to shut off the
water valve coils. Once the machine has achieved it's water level, the wash cylinder will continue to agitate
as programmed. The time on the front display will count down as the stage progresses. The time of the
stage is programmable up 30 minutes per stage used.
When the bath ends the control PCB signals the relay PCB to remove 120 VAC power from red/white wire
at J4-3 going to the drain valve. With voltage removed, the normally-open, spring-loaded drain valve will
open allowing water to exit the machine until the tub is empty. This resets the pressure switch back to an
(open contact) empty level and removes the 12vdc connection through the pressure switch from the blue
wire to the blue/yellow and blue/red wires. The same options can be set for each stage through. It is pos-
sible to hold the drain valve and keep the bath water in the tub to start the next stage or extend the stage
time.
Note: The control can be programed to hold the drain and extend advance into the next stage. This allows
for roll over stage possibilities.
Spin and Extract Circuit
Once the pressure switch achieves empty (open circuit) level, the washer is capable of a programmed spin
speed, from 60 to 200 G-Force at the end of each stage. The control PCB sends a signal to the variable
frequency drive via the data cable from P-6 to the VFD RJ-11. The rotation as viewed from front during
spin will be counter-clockwise.
At the end of the spin, the basket will come to a stop with the assistance of the dynamic braking resis-
tors wired in parallel to the variable frequency drive. The washer will then tumble for 45 seconds to let the
clothes shake loose from the basket and then stop.
Thermoactuator and Shake Out Circuit
The Lock Thermoactuator is turned off after deceleration from the final spin is complete and just before
the additional 3 agitation motions (“shakeout” portion) are beginning. Deceleration from final spin is con
-
sidered to be complete when the VFD is registering 0 Hz for actual frequency and the control is registering
less than 10 RPM from the proximity sensor for 10 seconds. Both of these conditions must be satisfied for
the Unlock Thermoatuator to turn on. Once powered this will push the safety block mechanism out of the
way of the door lock gear motor lever.
End of Cycle Circuit
Once the machine stopped, 3 things occur:
1st) The beeper will signal for 5 seconds letting the user know that it is the end of the cycle.
2nd) The control PCB signals the relay PCB to remove power from the red/brown wire at J4-6 which allows
the door lock gear motor to unlock.
3rd) The main control PCB resets when the S1,S2,S3,S5 opens and door is opened, allowing the display to
reset when door is opened.
