SOURCE: LG INTELLOWASHER DD 7KG DOOR LOCK STAYS ON WAY TO LONG

Never heard of that; I would try a new door latch as I have never had a bad control issue with the operation of the door latch. There is no real way to test it. I can getb you the latch if interested. I cannot see your reply due to some tech issue w/ the site, so it may be a day or so before I can reply again. Please leave feedback for me if appropriate. Thanks

You are right!

Bearings have to be replaced. Replace with the same type and design. All the bearings connected to the washer center shaft has to be replaced at the same time with new set.

Replace the water seals also connected to this. Check the shaft where the bearing sits, for any abrasions or metal damage.

Check the bearing housing also. While carrying out these repairs check the drive belt also. If needed replace it.

If you are happy with the machine outer body and other aspects repair it and re-use it.

SE is 'sensor error' This could be anything from a loose wire to a faulty Hall sensor or even a main board failure......You probably need an LG technician. Your machine sounds like it's worth repairing.. Get quotes.........Good luck...Nomess

It could be that the springs have become lazy (stretched) and not supporting the spinning weight as good as they once did or as happened to me one of the shock absorbers at the base of the unit has come adrift from its securing point. Replacement parts are easily available but you will need someone strong to fit them with all that new tension.
