Cpap hose ... Necessary to wash if not using humidifier?

I used clean the hose by running the water for my air curve 10 with the heated humidifier. However, the tube is broken that can't be recognized by the cpap as heated tube. Guess when running the water even I am carful not to touch the plug that will plug into the cpap machine, somehow, it still got in the water or whatever. So I have to get a new one, I don't even clean it anymore.
