Michael G Ware , MA April 12, 2021 Appliance: LG Dishwasher LDS5811ST-01 Lg Dishwasher Lds5811st-01: Dishwasher was not draining or cleaning properly. How to replace Sump And Motor Assembly. I bought the new sump assembly, watched a few YouTube's on how to replace it and it worked out well. Inspect the item when you do get it. My part had one broken retainer tab but still decided to use it. I planned on 2 hours but the removal of the dishwasher tool more time and I finished in about 3 hours. Ran a small rinse cycle first and it worked out well then did a full load and that went well also. Check for leaks often and listen for the sound that it makes to make sure it is cycling and pumping the water like it should. The fix was easy but took longer than expected and is a much better option than buying a new dishwasher.
