I used the diagnostics to see why my 6 year old Samsung front loader makes a strange noise followed by a bad smell after it attempts the spin cycle. I used the manual that's taped to the back of the unit to put it in service mode, this helped me discover 2 things; My stay-at-home wife is not lying, she does a ton of laundry (over 4000 washes since we got the washer) AND it gets almost up to 700 rpms in the spin cycle and then shuts off and then tries again and again.
I found a few videos that described the problem perfectly, the spider arm basically disintegrates and the tub wobbles all over the place. Great design Samsung... Most videos said the washer is now garbage, pro repair was over $400. I knew I could fix it myself and I found the parts on Appliancepartspros.com including a video that showed the entire process. I am very handy and after watching the video, I tore it down in under 45mins, it was like I already did it before and knew exactly what I was doing. Even my wife was impressed, and that is no easy feat.
I needed a new spider and 6 new bolts for under $150 shipped. I chose to get a tub washer and seal too, for an extra $20 it was just sensible to get. I used standard tools including a 10mm, 13mm, and 19mm socket plus basic tools. Reassembly was not bad and I didn't even have any extra parts ;-).
I spent most of the time cleaning out the nastiness from 6 years of use. It runs like new and we cancelled the order for a new washer and dryer. $2300 back in my pocket !!!
You do have to tear the washer all the way down. This was very easy for me, but some people that do not do stuff like this could find it quite challenging. Please check all the hoses and connections after reassembly. I forgot one hose and watched the first cycle clean my floor. Actually, I guess I cleaned it as I sopped up the water...
I hope this helps, Happy fixing!
Samsung, if you are reading this, please fire the engineer that decided to use that self destructing metal. You should probably fire the engineer that recently designed the latest exploding washer that just got recalled too.
