Water Remaining in Gasket Around Door

its not glued - probably just stuck - if it does rip on you, it's cheap and easy to replace

On some Kenmore front load models, if the black gasket around the door opening is unseated (for example, because you drag some heavy wet laundry over it) the door will not engage the lock and stay closed. This is a feature to prevent the washer from leaking when the gasket is not sealed. To fix it, simply reseat the gasket and the door will close and lock.

this may be something stuck in the gasket(rubber) that seals the door. Fold down the gasket all thew way around the gasket, remove any thing hat may be there. This could be coins, small articles of clothing, or a wash cloth.

If no obstruction is found, it probrbly require replacement of the door gasket/seal.

Problem:
The seal design on the washer traps water causing mildew to grow.

Solution:

If the door gasket has a small hole at the six o'clock position--it is clogged with soap scum. Use compressed air to blow this hole clear.
This allows water to drain back into the tub
If there's no hole--this is an older model LG which did not have this upgrade
Wiping the door gasket with a rag after the LAST cycle of the day helps prevent debris from accumulating. Some consumers add (1) teaspoon of bleach to a spray bottle with water--and spray the older type gaskets after the final laundry load finished--to keep the gasket clean.

You need to use some bleach and clean the washer out. I also wipe the rubber around the door opening and leave the door open airing out the machine. The rubber gasket will grow black mold.

Check inside the door on the bellows gasket to make sure the inlet area (normally at the 10 o'clock position) is properly positioned around the water inlet, sometimes these work themselves off the inlet nozzle and can casue a leak when the washer is filling up.

Also, carefully run your hand around the bellows gasket to see if you can find any small holes that cold be letting water leak out. You'll need a flashlight to make this easier. It is hardly ever the hinges that causes a leak since the hinges are mounted outside of the door seal gasket (bellows gasket) and aren't ever exposed to the water.
