Dishwasher door freefalls

Second attemp to send this message . The dishwasher door falls without resistence . What do I need to do or install/replace to fix the problem ? Do I need a repairman or is this something I can do myself ? Thank you for your help !!

Either the door springs broke, or they just came off. If you have to replace them, here’s the part number for the kit.
