Baumatic BDW13 dispenser door

I have a baumatic integrated dishwasher. The flip-up door on the dispenser drawer is cracked, and as a result either doesn’t shut properly or doesn’t open properly, depending on what mood the dishwasher is in. Either way it’s stopping the detergent from getting out.
I want to try and get a replacement door without shelling out £50 for the whole dispenser assembly. Is this possible, and is it something I could fit myself?

Many thanks,

Thom
