Hi. I'm GRN Appliance. I recently acquired a 10-year-old Samsung Bubble Wash 7.5 KG front loader model number WF1752WPW on claims that it was having trouble balancing. When trying to diagnose it, it gave me a 3E error code, indicating some sort of motor connectivity problem. The carbon brushes were fine, and I inspected the wiring as best as I could, and it all seems fine to me. Any thoughts on what it is and how to fix it would be very much appreciated. Thanks!

Problem Identified.
I figured out how to test the tacho sensor using the multimeter, and it gave me a reading back, so that's not the problem. Before ruling out the motor as the problem, I checked the second carbon brush. I had inspected one of them earlier, but it was okay. Regardless, I checked the other one, and sure enough, it was worn. Not sure why one wore out faster than the other, but I'm just glad that I know what the issue is now. Thank you for your help!

Glad you got the problem fixed. Yes it's normal for the brushes to wear unevenly.
Welcome and kia ora. I'm an Aussie and love visiting NZ. We visited Whakatane about 5 years ago, it's a beautiful location. My Dad was part of the construction team that built the Kawerau paper mill in the early 1950s. | ||

Update after running 2 loads:
So I can hear the bearings are sort of on their way out. It's not terribly noisy yet, but the sound is there, and I won't be able to do anything about it at least for now. Other than that, the machine appears to be balancing as it should and running nice and smoothly. When I return it to my neighbor's place, I'll still ensure that the machine is level and everything like that.

I’ve never dealt with any machines that use carbon brushes since the machines I have all have induction centrifugal start switches on them. I do however have a small collection of vacuums and so far the brushes on them seem to be in good shape, don’t think I’ll need to look into them since direct air vacuums don’t go through carbon brushes as fast compared to a bypass type of vacuum.
