I Googled the whirlpool web address and one of the sites was appliancepartspros.com. I clicked on that site and was amazed with the ease of finding all I needed to know about my washer by simply entering it's model number. I found the part I needed and a video showing how to install it. The price was very reasonable and the video extremely easy to follow so I ordered the part. I received the part the following day. I noticed on the website it estimated an installation time of 15 minutes so out of curiosity I timed my work. It tookme 10 minutes to remove the old pump and install the new. What a savings of time and money!!
