Bosch WVH28360GB

Morning all,

I wonder if you could offer a suggestion on a Bosch WVH28360GB washing machine. The door isn’t locking when you shut it and select a program. You hear it attempt to lock (there’s a clicking noise from the interlock). But it then beeps and refuses to start a cycle. I’ve replaced the interlock and checked the PCB and wiring for damage. Am I missing something or is it likely to be the PCB?
