How to replace Circulation Motor. So easy - Wife did it ! I'm currently laid up with a back problem so all i did was hold the flashlight. We Let it go until it died - ordered your new circulation motor. Arrived in 3 days. Watched the provided video which was 100% accurate. While we did not compete with the 6:53 minute instructional video (probably took about an hour and a half) the results were SO nice to have our dishwasher running in the background without having to yell ! So proud of Kathie ! AND she got Friday morning bragging rights and credibility from co-workers and bosses for having done the job virtually by herself !
