Fabricio A. for Model Number wtw6400sw3 My washer machine has a displaying cod message that said SD at the end of washing the clothes. The machine also does not drain the water or spin. Thank for helping me.
Answer Hi. The SD code is a slow drain. Remove the lower kick panel and remove the drain pump cover. Clean all debris. Feel inside to see if the pump impeller is spinning loose on the shaft. If so then replace the pump part # W10536347. Make sure the pump intake hose is clear. You may have to remove the hose off the tub and see if there is a blockage at the tub hole as well. Fill the tub with a small /cold normal wash and after a few min. advance it into a drain. Do this over and over to drain the suds. Remoive the pressure switch tubing and blow back into the tub to clear the tubing of suds or lint. Cut back to 1/3 of the soap fill so this does not occur again. Todays detergent is formmulated to clean well with less water. Use Afffresh washer cleaner monthly part W10549845 to maintain proper performance levels. Thank You. Read More...
