FIXED Samsung Washer WF45K6200AW/A2 not completing cycle

Samsung Washer WF45K6200AW/A2 (2017) not completing cycle. Got code 3c2. It starts the cycle but stops midway, and you can here the machine clicking trying to continue. I did all the basics, cleaned all the filters, make sure all the water inlets were clear etc. Now I am at the tacho sensor but not sure what the readings should be. My research for code 3c2 leads me into this direction. Can someone help me with troubleshooting this? I realize it could also be the curcit board. Searching for troubleshoot tools on this model. Thanks

Here's the service manual: https://drive.google.com/file/d/1Osz5OgKaQdYRxTFL6oq7pg90g5nKS3rv/view?usp=sharing

I don't see error code 3c2 listed, Are you absolutely sure that is the error code? error code 3C means--->Washing Motor Error and Hall Sensor Error--->Look on page 29 it tells you what it should read.

Ok thanks. There was more than one code, 3c2, ddc, bc2, dc, and 1c. Because I was tampering with things when I was trying to do a source of illumination. I think I trigered the others so I erased them and start over, then I got the 3c2 code. You're right I can't find any info for the specific 3c2. But I found a chart that groups these together and they all refer to the Hall Sensor error. I am going g to do all the testing and keep you posted. Thanks Jake!!

Ok, sounds good, yes let us know.

Ok, some extensive checking. I am a little confused with my results. I am sure you can help. I took the machine apart and took out the circuit board, did the testing from there. Disconnected the Winding Coil at the circuit board test across three wire Red, Blue, White on the coil side. Red/Blu =12.5oh. Red/Wht.= 12.7oh. Blu/Wht.= 12.3 oh. With the machine plugged in I got 112v from each wire on the circuit board side.

Now the Hall sensor, unplugged from the circuit board, I measured across all four wires orange/pink 25.90k oh. Oran/Red= 24.2k oh. Oran/Blu 24.9k oh. On circuit board side with machine plugged in Oran/Pink =1.31 k oh., Oran/Red= 2.06 k oh. Oran/Blu 2.51k oh. What do you gather from these tests, and do I need to do more?

The findings are far off from what is mentioned In the manual. I also had to used a different method to retrieve the codes as per stated for this specific model. Do I need a Hall sensor, Winding Coil or both? Thanks

Disconnected the Winding Coil at the circuit board test across three wire Red, Blue, White on the coil side. Red/Blu =12.5oh. Red/Wht.= 12.7oh. Blu/Wht.= 12.3 oh.

Those are not reading properly, the service manual says it should read 6 ohms across ANY two out of the three wires.

Now the Hall sensor, unplugged from the circuit board, I measured across all four wires orange/pink 25.90k oh. Oran/Red= 24.2k oh. Oran/Blu 24.9k oh. On circuit board side with machine plugged in Oran/Pink =1.31 k oh., Oran/Red= 2.06 k oh. Oran/Blu 2.51k oh. What do you gather from these tests, and do I need to do more?

The service manual says it should be 2-4 M ohms.

So that's not reading good either.

Here's the part you'd need below, its the stator motor that comes with the new hall sensor too.

Drive Motor Stator


There is a video when you click the stator motor part link that shows you how to remove and replace it.

Good Morning, got the new Winding Coil with the Hall Sensor and did some comparison test before connecting to machine. Findings:-- on the Hall Sensor (Blue, Orange, Red,Pink). New unit,pk.& blu.=4.71k ohms, pk.& red=4.71k ohms. Pk.& org.=24.09k ohms. Blu & reb=9.42k ohms. Blu & Org.= 22.43k ohms. Org. & Red=22.61k ohms. All these readings are approximately the same as the one I took off my machine, give and take a few hundredths of a kohms. Connected to machine, Same issues. Is it possible for this unit to be defective? Or do I need to check other areas? HELP!!! PS:- in my previous postings the test results were made with the unit connected to machine but unplugged from circuit board.

The service manual says it should be 2-4 M ohms.

the service manual says it should read 6 ohms across ANY two out of the three wires.

So the service manual must be wrong? That's very strange.

I don't know what else it could be, it would be good to contact Samsung to come out and see what's going on.

Its difficult to OHM TEST parts with a faulty service manual. LOL

Still no solution, I'll keep you posted on any new results. Trying to find a way to test the circuit boards.

I got same issue 3c2 error on my Samsung WF45K6200AW/A2 washing machine, Motor winding resistance is about 12.5 Ohm. Resistance between 1-3 and 1-4 of Hall sensor connector is 12/13KOhm range. I read another forum with same issue he replaced main board and problem fixed. I am not sure for mine if its main board or motor driver board. Please update if you progress on it.

We have the same issue issue 3c2 error on my Samsung WF45K6200AW/A2 washing machine, it will work sometimes in quick wash mode, we tried allllll the trouble shooting and still the same, think its the main board. Any updates?

I am ordering the main board now, will update as soon as possible. Hope this solves the problem.

We had an appliance repair come to the house and it turned out to be the inverter.

 

[Jake]

Interesting, wonder why the service manual never mentioned inverter?

Here's the motor inverter board:

GOOD AFTERNOON guys, Jfolds, Arino and Jake. Just completed the installation of the motor inverter board (DC92-01531C) tested with a quick wash cycle, did it completely, went on to a regular cycle wallah!! All done, machine works like a charm.
Summary:- the manual does not show how to trouble shoot 3c2 code. Most of the information for testing (Drive motor stator) are different from the actual readings. I now have a main board and motor stator which I never needed, but keeping them for whatever happens in the future. Still doesn't know why there is no trouble shooting for this. Hope this thread helps someone in the future. Thanks Jfold followed your lead.. Great taking to you guys.

Excellent @Chickenman7 glad to hear the new motor inverter board fixed yours too.

Thanks for the update and the added information!
