How to reattach the side panel to a built-in dishwasher?

My son has a built-in dishwasher in his condo.
The screw came out of the side panel to which it is attached.
The side panel looks like fiberboard. The place where the screw came out needs to be firmed up.
I think that it needs to be filled in with wood filler - scoop out the loose stuff then fill in.
Am I correct?
Can it hold the screw when it is filled in with wood filler and dry?

Or is there a bettter method of repair?
