Product review (5 stars): Samsung Washer not able to start high spin speed cycle - Repaired!
We had purchased a Samsung Front Load Washer WF42H5000AW on Aug 2014 from Sears. It was good at washing clothes clean until it could no longer go into the high spin speed cycle. My parents had bought the Samsung washer and dryer pair before I bought my Samsung washer. Similar to my washer, after 2.5 years of normal use it was not able to go into high spin cycle. It would seem that this is a very common problem for Samsung Front Load Washers after 2.5 years of ownership.
After hours of online research, I narrowed the problem down to a malfunctioning Inverter Board which controls drum's high spin speed (part # DC92-01531B). Contacted Samsung to get a replacement part, but they would only let their certified technicians look at repairing and replacing parts in washers. My washer warranty expired 1.5 years ago, so a service call will cost me at least $100, then add on that parts and labor costs.
A few YouTube videos taught me how to replace the board myself. It took only 15 minutes to switch out the part located in the back and bottom of the washer. If this was helpful, click on the "Yes" below so it could show up at the top of all reviews to help others. Thanks for reading and good luck!
