I would like to replace the 8' factory drain hose that came with my Frigidaire dishwasher (model FMB330RGC0) with a 6' hose to save space under the sink. I ordered a replacement hose, which needs to have a right angle fitting on the dishwasher side. However, once I unplugged the old hose, I noticed that, even though the diameter of the hose fitting is the same, the factory one has some ribbing:
to match the stub on the dishwasher:
The aftermarket 6' hose has a plain fitting with no ribbing:
I thought Frigidaire purposely did this to proprietarize and prevent the aftermarket products from being used on their appliances so I called to see if I can order theirs in 6' but they didn't have it and the lady I talked to didn't know any more technical details.
Based on the pictures, can you tell if I can somehow adapt the new plain hose to go over the stub that has ribbing?
