LG F12B9QD Washing Machine: Dealing with LE Error and Motor Overload Issues

Question

Hello! I have a problem with the washing machine as in the subject. The washing machine once in a while displays an LE error. The washing machine behaves identically as in the 20-21 second on the video on YT: I removed the rotation sensor, measured-everything on it seems to be fine, ie the...

It turns out that this sensor can be replaced:

The washing machine has a sensor marked: 6501KW2001B. Replacement for Aswo, as well as the one you wrote about @cezet it's 6501KW2001A. Are these parts different or are they completely covariate? Or maybe one of them is an improved version?

Hello! I apologize for reheating, but I have a similar problem. The sensor turned out to be damaged. However, due to the fact that urgent time I would prefer to replace the hallotrons inside the sensor. The problem is that it's hard for me to find the right replacements. The designation on those inside is W12C 45U3. Could someone help me and tell you what to put in there?

For those who will have a similar problem, I leave confirmed info. Hall sensor, position "rotor", numbers 6501KW2001A has two Hall sensors. If someone is in a hurry, or there is no home appliances service at hand, they can be exchanged TLE4935L. It will work. Probably every other hallotron with similar parameters will also work together.

Hello.
I know that the answer has already been given in this topic and everything would be ok, but after downloading the engine and disassembling it, I do not see the Hall sensor. In the photo you can see that there is a place for it, but it is not there and there is no plug either. My question is does every LG washing machine have this sensor and is it located in the same place?

Here's what the original stator looks like:

And there is no Hall sensor there either. So where should I look for the reason that the engine does not turn under load?

It was a long time ago, but from what I remember the sensor was mounted somewhere outside the engine. You didn't have to disassemble the engine to get to it. It should also be in this washer dryer due to the fact that it is a BLDC motor, so the controller should know the position of the impeller. Although they are in the BLDC application without such a sensor (feedback), but in the washing machine I suspect that it should rather be found.

In my case, after starting the washing machine program, the drum rotated about 5-10 degrees and stopped. There were two attempts and it was throwing a motor/drum overload error.

In my case, after starting a washing machine program, the drum rotated about 5-10 degrees and stopped. There were two attempts and it gave a motor/drum overload error. It's exactly the same for me. Only I bought it damaged, but no one knew what was wrong with it. I do not know if anyone has pulled something here before, because I clearly do not have this sensor and the plug that connects to it. There is only one plug for the stator. Can colleagues help me where to look for it, is it connected to the module? I can't find a sensor for this model on north.pl. So that's how my problem was solved after changing the engine to another one. It turned out that water from the leaking drum was dripping onto the motor winding and it was damaged. In fact, in this model, the Hall sensor is not present at the stator, only in the module. Regards

>>20321543Hi I got same situation in my LG WD-S16VBD. I don’t see hall sensor as demonstration in Youtube video. People said maybe LG changed to use sensorless solution Added after 1 [minutes]:>>20321543Hi I got same situation in my LG WD-S16VBD. I don’t see hall sensor as demonstration in Youtube video.
