Bosch D/W -SRV43A23GB/16 New module, can’t configure.

I have fitted a new control module to this dishwasher, together with a replacement dispenser wax motor, which I believe caused the demise of the old one. When I tried to configure the replacement module (00490486) to be compatible with this model, I couldn’t get it into configuration mode (Holding the button combination only caused the pump to run intermittently). Has anyone else come across this. Only thing unusual that I noted was that the programme button order was not on the configuration list – a detail my customer was prepared to live with. Your thoughts would be appreciated. Graham
