 Washing machine backing up in the drain pipe
Author: brothenb (WA)

I have a perplexing problem. When my washging machine drains, the drain pipe the hose goes into backs up. It just started doing it today. However, I took the drain hose out and ran a garden hose into the drain pipe and it drains with no problem at all, so it seems the drain pipe itself is clear. I let the garden hose run in the drain pipe for about 10 minutes without any problem at all. After I ran the garden hose test, I put the washing machine drain hose back into the drain pipe, put the machine on rinse cycle to add water to the machine then let it start draining again and again it started backing up out of the drain pipe again. Any suggestions? I'm really perlexed on this one.

Additional information - when the pipe backs up, I turn the washer off and it immediately drains. I turn it on again and it backs up. It's almost like there is too much water draining at one time from the washer? The hose that runs from the washer into the drain pipe is a plastic flex hose and it extends into the drain pipe about a foot.

What I don't understand is that when I run a garden hose into the drain pipe, it works fine, no back up and drains like any other drain

Thanks

Your wash machine is probably putting out a higher gpm than the garden hose. Try inserting a piece of 3/4" copper pipe about 8" long into the discharge hose and fasten it with a hose clamp. This will restrict the flow and hopefully your drain will handle the flow.

the plastic flex hose already narrows down to a plastic shaft that is about 8 inches long and the opening of that shaft is 3/4" inch in diameter. I've owned this house for 5 years and haven't had any problems until today, do you think I should try something even smaller? Is it possible that there is something in the washing machine that controls the output flow that maybe stopped working? Sorry, I'm not very knowledgeable when it comes to plumbing and it probably shows in my questions :-)

You seem to have developed a down stream drainage problem and a full sized snaking of the discharge line seems to be called for.

I've never seen any kind of internal regulator on a washer discharge. I think your washer is fine. I'll bet you have a partial blockage somewhere downstream from the machine. Best Wishes.

look at the thread "clothes washer backup" below, that might be the problem. when i encountered it, it sure looked like the drain backing up.

Agree. Not only can a slit appear in the hook of a rubber hose, they can also easlily appear in one of the segments of plastic flex hose, which also may seem to be a drain problem at first.
Check the discharge hose closely when it's rinsing. Thanks for the head's up.

Well, it doesn't appear to be the flex hose, so I guess I'm calling a plumber :-)
