In Topic: LG WM2101HW - Wash Drum Hitting Washer Door

Hi John, the machine is on a concrete slab. The dryer is mounted above using a stacking kit. The unit is in heated room which is constantly around 70F.

Thank you for the manual. Based on a comparison of the unit and service manual last night, all LG's are essentially the same construction. The build quality seems to be pretty good. Time will tell regarding the design. I have confirmed it is indeed air pressure popping the door open by moving the drum manually. I removed and inspected the "bellows" rear vent hose and the dispenser hose. Both have pop valves (they look like mushrooms) that close each hose when activated, although the valves are not illustrated in the service manual I have. The valves are activated by air pressure created by the drum during movement. The valves close before maximum pressure is achieved, which then creates a pressure buildup, mainly during front-back drum movement - this pops the door open until it is stopped by the door lock. Through trial and error, the rear "bellows" pop valve is required to keep water and suds from exiting the rear of the unit. The door problem was solved by removing the pop valve on the dispenser hose. This allows more air to move and reduces the pressure buildup in the drum. There does not seem to be any major side effects from removing the pop valve in the dispenser hose. Maybe there is a little more noise, but very minimal. Does anyone know what the pop valve in the dispenser hose is supposed to do? Maybe the pop valves are there to reduce noise, keep water in, and perhaps control the max drum excursion through air vent control. If the latter is true, it's crude and doesn't do a very good job.

My main question now is: why did my unit do this in the first place? Other units do not seem to have this problem. Perhaps there is a third pop valve in a hose under the drum that is stuck shut?


Thanks again for the manual!

Hi John, if there are any keywords to an existing topic can you let me know? I've searched the forum to no avail. Do you recall if there is a fix? If this was a common problem i am sure it would be all over the internet, or no? The wash drum air venting doesn't seem to be sufficient. The repair people just replaced the shocks and it still has the problem. I kept the old shocks are they are in working order (all three have the same damping characteristics). My old beach towels had a lot of residual regular detergent in them on my first wash and the machine did "over-sud". Maybe this made some kind of vent valve sticky?

Would you happen to have a WM2101 service manual you can share? I would really appreciate it.

It was a mixed medium load. No matter the load, it is not acceptable. Has anyone seen this before?

Hi all, any idea what is going on here? Please see my video. Does anyone have a service manual? I also posted a request in the service manual request forum.
