after pressing "WASH", "RINSE", "SPIN" button simultaniously, press "POWER" button.
ALL LED On --> SPIN button ---> ALL LED off
--> L C (Lock Close) ---> r (Motor right) --> L (Motor Left)
--> F ( Fan Motor) ---> H (Hot V/V) --> C (Cold V/V) --> b (Pre whsh V/V) --> d ( dry V/V)
--> bb (bubble) --> h1 (Wash heater)--> h2(Dry heater) --> dr (Drain motor On)
-->L O(Lock S/W Open)
2) More tails
1 LED test can be done with all LED On.
2 All sensor conditions will be shown on PCB during processing.
