I know it is too late for others but for any later users who have the same problem.
Switch power off to machine.
Slide it out from the unit it is built in ( onloy as far as you need to access the 4 x hex screws holding the top panel on.
Remove these four screws and take off the top panel and put it aside.
You should then be able to see the switch panel which is normally clipped to the back of the front panel. The plastic retaining clips can break off causing the button panel do what yours has.
However all is not lost if they are broken as the switch panel should have screw holes at the top and bottom centre of it.
Just get a small self tapping screw and screw it through the top hole with the button panel held in position and clipped with any remaining unbroken lugs.This should prove a good enough fix to hold the panel as long as you remember to go easy when operating the buttons.
It is a bit fiddly getting the screw to the hole but it can be done - I suggest the use of a magnetised stubby screwdriver.
Put the top panel back on slide the machine back in it's housing and job done.
Dont throw your machine away because of this fault it will take a max 30 mins from start to finish.
