Fix it yourself
They are the same and I had the same problem. I couldn’t get it to engage. It didn’t make sense to me. I thought the shower must be different. Went out and read the manufacturer’s number off the door side port. Ordered a hose that would fit. It showed up and was the same as the shower hose. So I grabbed a Phillips screwdriver and pushed it in. WOW low and behold it was just stuck. Now I have 2 hoses because I thought the fittings were different. They are not, it was really stuck. Give it a constant even amount of pressure until it unfreezes. You’ll know it.
