Ray C Reston , VA December 19, 2017 Appliance: LG Dishwasher LDS4821ST Lg Dishwasher Lds4821st: Le code on lg direct drive dishwasher. How to replace Dishwasher Impeller Assembly. LE code wasn't in user guide! Found it on the internets, linked to ApplianceParts Pros.com. Said it was pump motor failure, $100 seemed like a lot, but the video was clear as day, saved me time, which is money (certainly compared to the repair call!). Ordered the part, came the next day, did the install in 1.5 hours, worked like new. Thanks, guys! Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
