Dear Technician,
I called your parts dept. to purchase a new coupler for this unit and was told that this part can't be purchased separately. Since I will need to purchase the entire hose and coupler assembly, and this part does not come with installation instructions, can you tell me how difficult the installation is? I have successfully replaced the door latch on this same unit about a year ago without any problem, but replacing this part (#AP2108777) seems more complicated.
In advance, I appreciate your time in solving my problem.
