Hi

My washer has started having similar problems to others with the 3E2 error...cycle starts but drum doesn't spin. Happened intermittently at first and now the drum won't go at all, even in test mode.

Followed the fast track troubleshooting sheet, stator measuring 11-12 ohms (troubleshooting sheet says 6 but everywhere i've found people have been getting readings of 11-12).

On the fast track sheet, page 9 has a troubleshooting section specific to the inverter board, and you're supposed to get 4.6 ohms, but i'm not getting anything near that. Based on the other threads, i figured i'd start by replacing the inverter board since the stator and rotor look ok.

Three questions:

1. My board is DC92-01378C which has been discontinued. Is an acceptable replacement DC92-01531B? Someone else on the forum seems to have used this and had ok results.
2. When I took the rotor off, I broke a section of the stator (the ceramic section near the bolt holes, not the windings). Resistance is still reading 11-12 ohms as shown above. Is this ok as long as the windings are intact and it is structurally ok?
3. What kind of threadlocker should I use to put the rotor back on?

Are you referring to this thread:

Samsung Washer WF42H5000AW/A2 3E2 Error code

Hello, I am having issues with my Samsung front loader. It pauses at around 8-12 minutes into any cycle. At first I was able to just hit start again and it would end up finishing the cycle. Eventually it got to the point that it would pause and would not finish the cycle and then it would chime...

That I don't know for sure if its still ok.

What kind of threadlocker should I use to put the rotor back on?

Apply loctite blue 242 threadlocker and re-tighten that bolt to keep it from loosening up again.

Here it is: Threadlockers from Loctite Products | Threadlocking / Mechanical Gasketing | Loctite Adhesives

Yes, referring to that thread!

Hoping the two parts are interchangeable.

Ok, yes it looks like it did work from what @chrischia said here:

Are there any other service manuals aside from the fast track troubleshooting?

Yes, here it is: https://drive.google.com/file/d/1vG5ROJ3XH0Nb3lnKXGSObEQfsj22jFwm/view?usp=share_link

Thanks Jake! Will let you know if that inverter board fixes the issue when it arrives later this week

 

[Jake]

Ok, sounds good.

 

[Xkse]

It was the inverter board. Thanks for the help!

 

[Jake]

Excellent, glad to hear the new inverter board fixed it.

Thanks for the update!

When you got your new inverter board did it pass this board test you posted? I ordered a used board the was "tested" before sending out and it fails this test like the one that came out of my washer.

Nope haha...similar readings as the "bad" one.

Have you had any issues since? I put the original board back in and it worked for 2 months and now getting the same issues of not finishing a cycle and getting the 3E2 error code. What else did you replace if anything?

No issues since replacing the board. But it’s been less than 3 months

Hi Jake! Hoping you can help me out. Was getting the same 3E2 error code but could still run all the test modes and calibrate. It would sometimes finish a cycle and other times not. Would try it in quick wash cycle and that would work a few times and then not. Worked for 2 months with no issues after pulling it apart, testing and putting back together without replacing anything. Suddenly wouldn't finish a cycle and getting the code again, and everything seemed to point to inverter board so I got a "new" one. Put it in and it wouldn't even start a wash cycle, it couldn't calibrate, run spin test or anything else. Put the original board back in and it can still do all those things and just worked for a couple loads. After further research it sounds like it could be a few things like the main control module or hall sensor. Any thoughts would be greatly appreciated!

That seems to me you possibly received a defective new inverter board, I'd contact the place where you got it from and have them exchange it for another new one.

Definitely returning that part but as I continue research I’m seeing others saying to replace different parts like the main controle module. Do you think it’s the inverter board or should I be looking elsewhere? Thank you for your help!

 

[Jake]

That's what it sounds like to me the inverter board.

I originally checked all of the things you mentioned and was only left with the inverter board… and the new one had the exact same resistance as the “bad” one… but it worked!

Did you end up installing DC92-01531B instead of DC92-01378C? Thank you!
