Questions & Answers

For Lg Washer Rotor Position Sensor Assembly (Part Number: OEM21045243)

Mark for Model Number WM3677HW

My washer /dryer combo drum will not spin, and when the initial wash cycle starts the water will not shut off and starts to fill the drum. About a month ago I noticed my clothes were not fully drying. As time went on the motor seemed to be cycling several times before it would spin out, and hardly at all in dryer mode. Eventually the machine threw a "PF" fault code. I powered it down, unplugged it, powered it back up and it worked fine for about 30 minutes, and then it completely lost power. I found that the main PCB was blown. I replaced it. Now the machine once again powers up, but the motor and overfilling issues remain. I tried performing the "QC" tests called out in the factory service manual, but can't even get it to perform the 1st (tumble clockwise) test. What could possibly be the cause?

Hello Mark. Check the drain pumps and make sure they are not clogged, and the drain pipe is draining properly. If not, it will cause the problems your having. Hope this helps.

Hello Timba. Based on the information you provided, it sounds like the stator/sensor assembly will need to be replaced on the washer. You will need to replace both parts for the repair. Hope this helps.

Hi Nick. You need to replace the door latch for it to drain and spin properly. It will not reach high speed spin with the door latch issues. The latch part # is EBF49827801. Check your pump to make sure it is clear. The impeller will spin loose from the shaft and not spin out the water. This part # is 4681EA2001T. Good luck. Thank you.

Hi Many. Is there anything stuck in the front of your tub area? Is there anything stuck in your sump stopping the inner basket from turning? Take the back rotor off, inspect it for cracks in the magnets. The rotor part # is 4413ER1001C. Also check the RPS sensor, this part # is 6501KW2001A. Thank you. Hope this helps.
