Have been trying to retrieve all the check program test mode code detailled in the service manual table 4-3-1 pg 16, so far I have only been able to get the first code to work that is Rinse+Time Delay+PowerSW ( all at the same time). The table says I should get 3H/U2 and all LEDs lit i get 3H/U0 and all LEDS lit. Can you tell me what that code means also How do I retrieve the remaining codes in the table.

Thanks
