LDF5545SS LG Dishwasher - Overview

This is apparently a widely known issue for LG, and since their call center was closed due to Coronavirus, I had no luck getting them to cover the repair. Not wanting to wait weeks of months for them to get off their duffs, I ordered the part and unscrewed the six screws holding the control panel on and unplugged the old part, plugged in the new part, and replaced the screws.

Works great now.

Replacing this pump is pretty easy. Disconnect the power and drain hose, and pull your dishwasher out from the counter. Lay it on its side on a towel. There WILL be spillage. Disconnecting the pump is simple. There are a couple hoses, one single wire connection (the thermistor) and one multi-wire plug. The pump is held in place by a pair of thick rubber holders which can be pulled off by hand. That's it!

After removing the pump, I disassembled it to find out why these fail so soon. It's a very poor design. I found that the nose of the electric motor, where the bearings are located, sits in a plastic cup formed by the top of the pump body. Any leakage from the pump around the motor shaft will be held in place against the motor bearing. It has no place to go. This causes rusting of the bearing. I expect I'll be replacing this one in a few years. :(

But kudos to PartsSelect for getting the right pump assembly for me, after getting the wrong one from another supplier!

Ordered the roller from Parts Select, slid the roller over the little spindle sticking out of the bottom rack and snapped it in place. Job done in less than one minute.
