Thankyou verymuch for the reply. it really help me. i find the DRS switch at the rear and buttom of the logic card. i remember that i set it to S and forgot to bring back to R. now im getting a normal display. like i said last time before im getting a couple of Error Code. 30 and 54.
i have manual for this but i really dnt know what to check. in error "30" it says "Pump Motor, Foulty Circuit"

in the error "54" it says FC Lever Abnormality.
