A string wrapped around the coupling for the agitator. Laurence T. • Stockton, CA • March 28, 2014 Appliance: Model GHWN5250DOWS My Repair & Advice I had to remove the agitator to unwrap the string. In the process, aparently I did not get the agitator installed back on the coupling properly. It came off the adaptor during the spin cycle so i reinstalled it. Severa days later someting else got wrapped around the coupling causing the agitator to come off atgain durng the high speed spin cycle. ( Made quite a noise.) Only the top of the agitator was damaged so I have been able to reuse it.. On ispectiion I noticed that the coupling was eamaged (split). Installing the new coupling agitator was easy as the agitator was off. Everyting is reinstalled and seems to be working fine. Was this review helpful to you?
