LG WM2277HS spin and UE code issues
Posted 06 July 2013 - 07:28 PM
Serial number: 607KWAT02320
I ordered the replacement from repairclinic and with the videos had it installed in no time. Tried running vinegar to get the "drum cleansing and purification" process started. I have also bought the Tide Drum Cleaner pouches which I plan on using as well.
My machine will run most of its cycle, but gets hung at "spin mode". It never gets up to speed, but keeps draining and checking the load by spinning a few rotations each way then reversing. My last efforts have been following an old post from here. Tossed in a single towel and did the "rinse and spin" mode. It got down to 10 minutes showing and ran there for probably ten minutes before shutting down flashing and beeping the UE code.
I have done the best I can to verify it is level and true on garage concrete floor. There doesn't seem to be any true out of balance, but I am open to thoughts. Drum spins freely by hand. I have unplugged, spun both direction by hand. The lights cycle and then wait ten minutes plug back in. Still no joy.
Is this the main board? The HALL sensor bad? I appreciate your help in advance.

Channeling our ailing Brother john63 (please pray for his speedy recovery):
UE: Unbalance ErrorThis is an older (2005 or older) LG washer that uses a sensor mounted at the rear/back of the washer.This washer was also intended for use on *concrete* flooring (not wood).Unplug washerLooking at the back of the washer---remove the access panelOn the right side---you'll notice a spring-loaded arm that is mounted on the washer "shell".This is the BALL SENSOR.If the tub *bumps* this sensor frequently (or severely)---an error will be displayed and the spin cycle will be aborted.Examine the back of the washer (sheetmetal)---if it's *bent* inward---this will cause numerous false imbalance errors. It may be necessary to pull out the sheetmetal (to it's normal position).Another option would be to remove the plastic arm assembly entirely from the back of the washer---remove a single screw that secures the black BALL SENSOR---and then secure the BALL SENSOR to the sheetmetal of the washer (may need to drill 2 holes). Use nylon wire ties to secure the BALL SENSOR in an upright/normal position (same position as it was in the bracket).This will eliminate nuisance/triggered errors.This BALL SENSOR was discontinued by LG in favor of a much more reliable/accurate *software* system that monitors imbalanced loads.

Thanks for the suggestions. I believe however based on purchase date and serial number mine was made in July 2006. That saId, I don't recall seeing a tensioned arm when I removed the back panel to change the Hall/RPS sensor. I will pull it back apart tomorrow and check again.
Is there a way to check the main board? I verified tonight that the pump is indeed flowi freely when it drains, which was one other thought I had since it seems to stall in Rinse/Spin sessions throwing the UE code.

Are you saying you're does not have the ball sensor: http://www.repaircli...Number=WM2277HS
RepairClinic pulls it up for your model but it could be an error. Looking at diagrams for your model, I don't see one. Can you confirm?
Some things that will trigger the UE code:

I can see somethng that looks like that by leaning over machine with top off. I will take back panel off and work through the steps above. I will also order a replacement as my back panel isn't bent. I make sure to use both model and serial number when ordering to prevent wrong part if at all able.
Regarding the "replaced with software" I take it that is not a retrofit option for me? Thanks again

Hopefully this gets it working and I can order the replacement.
Are there any recommended service techs for the 77380 zipcode if not? I can't do three weeks without the washer while I try to fix, or HH6 is liable to veto me.

Replacing the ball sensor should take care of the problem. I have not seen the main board cause this problem but if the problem remains after replacing both the ball sensor (and assuming the back panel isn't bent) and hall sensor, then what else can it be? http://www.repaircli...Number=WM2277HS

I hope we are correct and this fixes it. Given it shows signs of having been wet, and the washer performs all functions up to that point. I am certain this should be it. Anything else would seemingly cause other issues or prevent other steps.

I might be confusing something in the bold. The panel is not "Bent" like from repeated hits, but more formed that way from factory. It is not just near the area of the BALL sensor though. It is majority of rear panel. Kicks out to allow room for stator ring more than anything.

Any parts ordered through the links at this site can be returned for any reason for one year, including electrical and electronic parts that have been installed.

Thanks Samurai, I think that is awesome of them to stand behind the product like that.
I won't return them though, it isn't their fault I am diagnosing the long form way. I can just save the original parts as spares against future catastrophe. Who knows, with the new and improved ones installed maybe the machine will actually work better too. Especially now that the drum is clean and will stay that way knowing the PROPER amount of detergent is being used.
I will report back once the new BALL Sensor shows and I get it installed. Hopefully it will be all good to go.

Samurai. Thanks for the guidance and asssit. My Tromm is back on full service duty and washing clothes. The BALL Sensor fixed it right away. As stated, I don't plan on returning other parts to repairclinix, but do plan on sharing this forum and their page by name if anyone asks for help.
Keep up the solid work and again thanks so very much.
