Mike C Georgiana , AL October 30, 2016 Appliance: Model KUIS1851 Circulation pump would not work I ordered a new circulation pump from appliance pros and replaced it and now it is working fine. just a note to others with this problem if you would run the cleaning cycle using the cleaner regularly which i didnt i probably would not have had this problem. it only took a couple of days to get the pump and took about 30 minutes to replace 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
