Qm S Silver Spring , MD March 23, 2015 Appliance: Samsung Washer- Horizontal Axis WF306BHW/XAA Samsung Washer Wf306bhw/Xaa: Water pump was struggling to get the water out of the machine debris was stuck in the pump and the impeller had broken. How to replace Washer Drain Pump. Opened up the back of the washer. The pump lies on the bottom frame in front of the rear service opening. There is an electrical power connector that can be removed by hand. Press down on the clip and pull the connector off the pump. There are 2 hoses connected to the pump with clips that can be released by hand. Get a towel to sop up any water that may still be in the lines and put them around and under the pump and hoses. Remove the hoses and let the water drain out. It has 3 bolts (I think they are 9/16th inch) that come out and release a frame that holds the pump to the main chassis. There is a screw on the bottom of the frame attached to the pump that needs to be removed. Then twist the pump and the frame in opposite directions to detach them from each other. Three screws hold the pump housing to the motor. Remove them taking notice of the alignment between the housing and the motor as well as which holes are being used. The housing will go onto the new pump and needs to line up again the same way. Reverse the steps and get ready to test. 27 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
