It's not really an "either/or" machine. You can control many functions just as you would in an older style, non-efficient, laundry washer.
Every washing machine for the past 50 years has been operated in part by a "computer." Until the last 10 to 15 years, the "computers" were comprised of heavy electrical switches called soleniods or relays. The switches were activated usually by a clock-timer mechanism (either a clock motor or a clock spring). In turn, the electrical switches activated mechanical valves, gears, levers, pumps and pulleys that filled the laudry tub at predetermined levels, spun or agitated the tub to wash at predetermined times and speeds, drained it, refilled it to rinse, spin and drain again.
This unit has a microprocessor that replaces the clock-motor cycle selector (that is why the cycle selector does not move like a clock through each cycle). The microprocessor also replaces most of the old fashioned solenoids and relays. This unit also has a more efficient motor and pump that replace most of the old gears, pulleys and levers.
