Why can't I just clean my internal drain hose rather than replacing it?

You can clean the internal drain hose of your washer rather than replacing it; however, you must remove it from your washer and let bleach sit in the entire hose until the mold comes off in order to properly clean the hose. 

Running special bleach cycles in your machine will not clean out the internal drain hose because the bleach only comes in contact with the moldy hose for a few seconds, as the water along with the bleach or cleaner is pumped out of the washer and down the drain.  

We recommned replacing the internal drain hose.  In addition, if you thoroughly clean the old, moldy hose you will have a clean replacement hose, if you ever need to replace the internal drain hose again.
