switch shuts off the water while agitating. The rinse
cycle consists of agitation for a predetermined amount
of time, then a spin mode with the pump running while
the machine goes into a series of 4 short 500 RPM
spins.
After all the rinse cycles have been completed, the
washer goes into a final high spin cycle to extract as
much water as possible from the clothing to prepare
them for the dryer. The spin speeds and duration of
this final high spin cycle are determined by the type of
wash cycle selected (refer to table).
NOTE: Washer may not reach 1000 RPM because
of an out-of balance condition. Control may limit
speed to 850, 650 or 500 RPM depending on severity
of out-of-balance condition.
Technical
The basic operational system of this washer consists of
the control, temperature switch, inverter control,
pressure switch, water valves, electric pump (or drain
valve), A.C. motor, transformer and cycle select
switch.
The control performs all timing functions like the
timer in a topload washer.
The inverter control uses a speed sensor on the motor
to measure the drum RPM. Before entering any spin
step, the inverter control measures the RPM of motor
to sense out-of-balance. The inverter control will try to
redistribute the clothes if an out-of-balance condition
exists; the inverter control will limit the spin speed to
several speeds depending on the severity of the out-of-
balance condition. If the out-of-balance condition is
severe enough, the inverter control will limit speed to
90 RPM and will not spin.
NOTE: An additional out-of-balance switch is used
to detect any out-of-balance condition during spins.
If this switch opens during a spin step, the inverter
control immediately stops and then restarts the
spin.
