Introduction
Use this guide to replace the pressure sensor in your LG front load washing machine.
The pressure sensor detects how much water is in the tub. The sensor LG uses in these washers have no moving parts, so it's unlikely to break. If the sensor malfunctions, the tub may under-fill or overfill.
This guide will work for most LG front load washing machines. This guide is written with a model WM3050CW washer. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.

Would this sensor also be responsible for an oe error. Drain line is clear and pump removes most of the water. The machine then continues to cycle through spin and drain with very little water coming out. When I remove the emergency drain line, it only has a couple cups of water in it.

I am having the same problem and I think that is my issue but am not sure.
Hi Fred (and John), sorry for the long wait! Yes, that sensor could be responsible, but the tube is often plugged. The machine tries to pump itself out because the sensor is still getting a full signal from trapped air because of a clog in the tube that can act like a check valve. Sometimes, this pressure will bleed off over time, and the machine will stop trying to run a perennial drain cycle. Take a look at this part of the LG washing machine troubleshooting sheet. Even though it is for "no water," the same system is involved.
