Austin M Liberty Twp , OH December 28, 2016 Appliance: LG Dishwasher LDF7932ST Lg Dishwasher Ldf7932st / Asteeus: Plastic piece on the upper dishwasher rack broke. How to replace Water Supply Tube. Order the new piece and it snapped right on. I had to add a few of the old pieces that attached because it was parts that made the whole piece up were discontinued. It is now working fine and have done two cleanings so far and the dishwasher seems to be working as new. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
