William W San Diego , CA June 02, 2015 Appliance: Model TPH21PRSM WW Lower door hinge bushing replacement and water filter Hinge kit worked perfectly. Water filter was a laugher. Responding to my wife's insistence that I change the filter, learned that she did not have one. We do now. Parts arrived lightening fast and were as promised. (I had a handyman do the work so; cannot discuss tools used.) Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
