Configure Zanussi PCB?

Hi
I have a Zanussi WJS-1265-W washer dryer and need to configure the PCB. I saw an excellent answer for a similar machine but it is not quite right for mine. Steps I believe are:
1. switch on with skip and start pressed
2. press fabrics 9 times to get to the error display
3. *** MISSING STEP NEEDED TO GET TO CODE INPUT ***
4. user skip and start to enter 16 digit code

Can anyone suggest what the missing step I need to do to get from the error display to PCB code input.
(Clicking skip on the error code display does nothing)

Thanks in advance for any pointers
