motor is running after the cycle is complete. it shuts off when I open the door.
For model number LDFN4542D
Hi Craig,
Thank you for your question. If the dishwasher drain pump motor continues to run after the cycle is complete, water has leaked into the base pan under the dishwasher and you will need to remove the dishwasher from the cabinet and tip it forward 45 degrees to drain the water. It will also continue to run if the drain is clogged or there are too many suds in the dishwasher. We hope this helps!

Will not drain after drain hose replacement. Possibly drain pump?
For model number LDFN4542D
Hello Bret, thank you for getting in touch. We would recommend making sure that you have installed the compatible drain hose correctly. If this is not the problem, then you may need to check the drain pump, part number PS12076726, to solve the problem. A malfunctioning drain pump can most probably cause this issue. We hope this helps!
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

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!
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
