Washer stinks when the water goes IN.

There is a terrible mildewy smell when the water is going in to my machine. It can't be smelled while it's washing or rinsing unless water is going into the machine. It can't be smelled while it is off, nor while adjitating unless the water is going in at the same time. I have a whirlpool front load HE machine.

It has nothing to do with the rubber seal you're using too much soap and softner and it's building up inside the tub. Run the hotest wash you have without any clothes in the unit and add a little bleach. If you see bubbles in the water when it's running that's excess soap you're washing out. Do it over and over until the water stays clear and then start using less soap. It only needs about a tablespoon for a full load.

I don't care how much soap it says to put into the washer you should only use two tablespoons of soap,the soap coats the drain line inside the pump or anywhere it touches and sticks to it,if you look at the rubber boot it might be black,this is soap scome not mold i know it's spelled wrong but they won't let me send it spelled correctly lol,also it sticks onto the spider gear and eats at it like acid,overloading and to much soap is what takes out the spider gear,you might have read people have a loud knocking in the washer when in spin,that's the spider gear,so if you use two tablespoons of HE soap this will not happen,also if it already smells you can try running a few loads with the hottest water.a cup of bleach and a tablespoon of baking soda and run it without any clothes and hopefully it will clean out some of the soap scale that's in the washer,also try to clean off the rubber boot seal,peal it open and at the very bottom in the center you'll see a few drain holes,clean them out,there might be hair or soap stuck in there,this will help the tub drain and dry faster,also wipe down the plastic door mostly at the bottom where it closes in where it meets the bottom rubber boot,i've seen hair stuck to it,when the door is closed water will run down the piece of hair like a wick and water will leak out the door because of a piece of hair.hope this helps you out,also white vinegar works like a mild acid,it might help clean the boot off,if you sick your index finger sideways like you're pointing and make a mark on the detergent cap it should be like a 1/4 inch high fill the soap to that level and you'll be fine.

I use vinegar instead of fabric softener. It works and helps with smell.

As water goes in, it vents air out back of washer. Try adding a cup of bleach to tub, fill softener dispenser with bleach and run an empty load on the hottest setting possible. You have mildew built up on outer drum. Do this once a week for awhile until smell goes away. Stop using softener. It leaves a residue in drum that can mildew. Use powdered detergent instead of liquid. The liquid also leaves a residue. Use plain white vinegar in place of softener on every load. It helps stop mildew since it is slightly acidic and as a bonus it helps remove soap residue from your clothes-plus it's inexpensive compared to softener. Leave door ajar after every wash and wipe down rubber door gasket on all sides. Good luck.

Do you have a U bend in the wastepipe that takes the water away from your machine

If not then any smells from the pipe run can come back up the outlet pipe

Once you have ran the machine it flushes away the old water and the smell goes away

You may have already found a solution, but I had this exact same problem. I ran the tub clean cycle with bleach and then switched to a powder HE detergent. I found some other posts that said that liquid HE detergent has some thing in it that causes that smell and the tub build up (not sure what?). I was hesitant that that could really make a difference but it has. It has only been a week, but so far everything smells great. Definitely worth a try.

Your water supply may have a high sulphur content.

Make sure you are using an HE branded detergent and cut back on the use of fabric softener to start. If you have a wm2077.2177 or 2277 LG has a board that has a tub clean program in it that can help. You can get the same result though by running a HOT bleach wash or use affresh, www.affresh.com It won't do it all in one go but over time it will make a difference. Leave your door open after the wash and wipe down the gasket as well.
You can help the process by changing the gasket, bellows and drain hose or you can try removing them and cleaning them out.
Another detergent on the market that works well is Persil, costs a bit more but you only use about 1/8 of a cup and it will last 3-4 months so is pretty cheap in the long run.

Note it is not the machine that has caused the problem but what has gone in it so try not to use so much and don't mix brands.
It will take a bit of time but you can turn it around.
