T1780WFHT (ABWETUS) LG Washer - Overview

Did the repair Myself. Saved $ 400.00 in the process.

I diagnosed by running a full wash. I watched it and when the water should have stopped it kept running. I unplugged the washer from the power and the water kept running. This told me the inlet valve was the issue and not an electronic issue. I stopped the water by closing the water valve manually. Replacing the inlet valve was very easy. Hardest part is moving the washer out of the laundry room. The videos online show very simple steps. Maybe 8 screws to remove and a couple of hoses and five electronic connectors. Take a photo of connectors before removing them to ensure you reconnect properly.

The problem was the valve suppling water to the bleach dispenser was not closing completely. This also caused some water leaking towards
the front of the washer. Replacing the entire valve assembly was very
easy. Unplug the washer, turn off the water, remove the 2 screws that attach the control panel, disconnect the water supplies, unplug the 5 solenoids, remove the hose clamps from the 2 hoses, remove the 3
screws that attach the valve assembly and remove it. Reassemble in reverse order, I did find that applying some water based personal lubricant to the 3 high pressure seals made assembly much easier.
