d5 error code

Washer Repair
1

Thanks upfront.
History.
Purchased between 2003 or 2004.
Moved to NC and it was stored in the basement for over two years.
Finally installed it for use at our small B&B and has always had an imbalance issue, but usable.
The unit has sat now unused for about a year.
Just tried to wash and am getting error code d5. There appears to be a broken button/micro switch above the door lock which I can activate by pushing in manually. I do not remember if this used to extend out but appears to be the case.
How do I remove the front panel or front cover to replace the door switch?
I have worked on many appliances/mechanical devices through the years but this one is not obvious.
All suggestions are greatly appreciated.
