The drain hose of my Haier portable dishwasher HDP18PA has sprung a leak. I want to replace the hose, but don't know how to access the connection of the hose to the machine. I started removing pieces from the back of the machine, but got nowhere.

Alternatively, can I just fix the leaking corrugated hose? If yes, how?
