Samsung washing machine model WA456drhdsu/aa, had to replace the water pump after six months due to a bad design. After I replaced the water pump I started having issues with the spin cycle throwing a dc error code and shutting down. I saw appliance parts pros video on you tube on replacing damper parts. I replaced all four damper parts as recommended and the washer works as if it were brand new. It took fifteen minutes like they said. You will need a putty knife, Phillips screwdriver, and a little bit of lithium grease and maybe some disposable gloves. An easy and cheap fix thanks to AppliancePartsPros.com. Thank you guys so much. Saved me a lot of money and time!
