On the front panel of the machine, close to the bottom, there is a ridge, and then the panel has an area at the very bottom that is recessed. Under the ridge, there are two screws.
Remove the screws, and grasp the front panel at the bottom. Pull it outward and swing the panel towards you.
At the top of the panel, the panel is held by two clip assemblies that will let go all by themselves if you will just keep swinging the panel outward and toward you.
Reassembly involves seating the top edge of the panel back on the clips, swinging the bottom of the panel back into place, and re-installing the screws.
The note I got said they had ordered parts for the machine, so it sounds like they knew what they were doing once they got inside. I did invite them to ask more questions here if needed.
