New door or new son!!

I have a Philips Whirlpool washing machine, model AWG 189WH that had its handle snap and an over-zealous teenage son decided to break the door to access his washing! The glass is intact but the circular plastic rim of the door is cracked. I can’t find this part on the spares site. Can anyone tell me what parts (ie their serial numbers) I will need and how much they are and whether it is something I can repair myself or whether I need to call someone in – and ultimately if it’s worth it. Thanks.
