original fault washer drained after 10 mins due to defective recirc pump this has been replaced
However this shorted the PCB out, this has now been replacedwith new unit. PCB and Programer not communicating due to PCB not being configured so displays E90.
How do I program the PCB with the following code = 990

Thanks. 990 is the the code supplied by electrolux AEG this relates to decimal 990 = binary 001111011110 = Hex 3DE so do i require software and a laptop or can this be programed from the user interface panel

The code required is a 16 digit hex code and the only people who have that are AEG.Sometimes there is a sticker on the old control unit with the code on.if so this is the code that you have to program in and store.There is a set sequence to enter it but it isn't easy to do and isn't easy to explain
