Hoover dishwasher HOD6615 Facia insert

Hi,
I’ve been out to look at a Hoover dishwasher HOD6615 today with the on/off switch pressed into the dishwasher. The fixing around the on/off switch has cracked like on many machines and the push button is just pushing back into the dishwasher. There nothing left for the arrow heads on the switch to grab.
The control panel/facia is only a very small piece of the front with the main part bottom and up the sides is the metal door, but I cant find the part number for it anywhere.

If anybody could help, it would really be appreciated.

Cheers
