LG Washer WM2016CW Won't start.

7 posts in this topic

Power on. Select wash cycle screen shows - - -. Press start/pause button nothing happens. Enter QC test mode screen flashes IU02 and then In80 alternatingly. I can hear the door lock trying to lock 2 clicks and then 2 more clicks. Then it chimes like 4 to 6 times. Press start/pause button nothing happens. Could this be a bad lock assembly? The machine shows no codes.

Indications are the door lock is damaged.  Curious as to why no dE fault code shown.  Check door switch connection at main pwb assy (red 3 pin yellow 4 pin & white 3 pin).  Also check door hook spring.

Here's the service manual for this unit:  http://appliantology.org/files/file/79-lg-washer-wm2016cw-service-manual/

 

Look on pages 36 and 37, has details on operation and testing the door lock assembly.  Verify the resistances inside the door lock assy, especially through the PTC,  and that you're getting proper voltage supply from the main control board.

Scott,

 

Thank you very much. Just what I was looking for. I also have WM2016CW Service Manual and it doesn't have these pages. Pagers are numbered (1-40). Cover page is identical. Go figure.

Just as I had thought "Bad Door Lock". Test point 2 to 4 should be 700 to 1500 Ω. It was open. I never realized that there were two different versions of that Service Manual. Doesn't make sense. Thanks again for your help.
