Dustin P Charlestown , IN July 23, 2016 Appliance: Samsung Washer WF218ANW/XAA-0000 Samsung Washer Wf218anw/Xaa-0000 / : Nd error code. How to replace Pcb Assy. Everyone thought it was the pump or lines filled with debris, but actually was the main control panel. The washer would stop at 21 Minutes remaining then get the nd error. Was blessed enough to have a relative that had same washing machine (model WF218ANB or WF218ANW) and was able to change the control panels. This solved the problem. Took about ten minutes to replace.Appliance parts pros had just what I needed and had it the very next day. Fast shipping and great service.
