open LED

76 and 78, in the main directly directive washtub 20 of the light of lighting device 50, illuminate the inside of cylinder 30 by the hole of cylinder 30 1 end inwalls.

So after connecting the power supply instruction, judge whether the user has selected laundry operations and whether imported washing sign on (S12).

As the result who judges (S12), if do not import sign on after the connection power supply is finished, whether the startup of then hitting from

LED

76 and 78 begins through the first pretrigger time period T1 (for example, about 3 minutes) (S13) constantly.

As the result who judges (S13), after opening

LED

76 and 78, promptly after connecting power supply, still do not import sign on if passed through the first pretrigger time period T1, then positive closing LED 76 and 78 (S14).

Simultaneously, as result of determination, if

open LED

76 and 78 and in the first pretrigger time period T1 user imported enabled instruction, even then the first pretrigger time period finished positive closing LED76 and 78 (S15) still as yet.

Meanwhile, activate door interlock switch assembly 13b and pinned door 8 side latch 13a, in washing process, open, the washing operation (S16) that sorry execution user selects to prevent door 8.
