washing machine drain hose length

According to my new washing machine's installation, the drain hose should not stick into the stand pipe more than 4 inches or mold could spread into the washing machine


I saw the installers stick in much more than 4 inches -- they didn't trim off the hose at all.

They also didn't use the supplied "elbow bracket" (a U-shape bend). What's the purpose of this?

I'm going to trim off the excess hose. But I'm curious how a longer hose could cause mold to spread into washing machine. Any idea?

Two reasons one is the washer will keep draining if the drain hose is stuck to far down the drain tube. After the first drain it will keep siphoning out the water. Second reason is the mold but not as common. I always sitck hose down a few inches no more than 5 or 6 and than tie it to the fill hoses with a tie wrap. You don't want the hose to come out and flood your house. I would not trim drain hose. It is all right to hang down.
