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?

  • there's not a lot of pressure, so it should be fine as long as it doesn't leak right away. – dandavis Oct 31 '19 at 18:17

You should be able to fit the hose over the fitting to the washer. Then get a hose clamp and install it over the hose and tighten it.

  • Looks like it's working so far. Fingers crossed – amphibient Oct 31 '19 at 1:22

    Yup, +1; the ribbing is just an extra safeguard against blow-out. I normally prefer the spring-type clamps because they self-tighten over time when the hose rubber softens with age, but I think I would use a screw-type clamp on that outlet pipe. And crank it good and tight. – Jimmy Fix-it Oct 31 '19 at 4:54
