LG washer load sensor not working. Sensing problem, how to repair

LG washers, especially the whirlpool models, are made with some of the most modernized equipment and technology available today for at home—as well as industrial sized washers.


LG washing machines have been implemented with new, modernized control panels and LED error as well as troubleshooting equipment to make dealing with errors, defects, and required maintenance all the more understandable and fixable for the average consumer.

If your LG washing machine is showing a load sensor error or is “misbehaving”, you may attempt one of three different resolutions.

Firstly, consider the prospective value of attempting to “reboot” your washer by following these steps:

Unplug your LG Washing Machine

Press and Hold the Start and Pause button for approximately 5 seconds or longer

Plus your machine back in, and see if the error still persists.

Whether or not your LG washing machine is showing the code error versus actually not registering load maximums or operating is significant—since an error could hypothetically be “temporarily” ignored while a legitimate defect would in turn prevent you from being able to use the machine until necessary repairs. As LG is a modern technology brand for washing machines, they have created an app for both Android and Apple devices that help you address and troubleshoot errors in a variety of ways.

LG whirlpool washing machines are designed with a “simple” error platform that provides two letters in which you can refer to your manual for to decode. Additionally, the free APP for your LG washing machine can be utilized to troubleshoot the error, make sense of it, and purchase tools or parts as necessary to attempt the repair on your own.

The LG washing machine app also impressively allows you to record the noises your washing machine is making, and will decipher, per the noises, what the likely cause is.

In fact, given the swath of free online Do It Yourself videos available, it isn’t necessarily impossible to save yourself hundreds of dollars or more if out of warranty—and attempt to repair the washer yourself.

These alternative solutions as opposed to jumping right into calling a technician, by instead browsing the online LG equipment forums, could make all the difference for both your peace of mind and your pocket.


How do washing machine sensors work

While the term “sensor” might be arbitrary in some technical aspects, it’s significant to consider that a sensor can come in the value of an internal physical mechanism such as a diaphragm, or even a sensor that reads pressure build up in a tool, simply toggling between washing mode settings automatically, per its preprogrammed steps or commands.

When it comes to washing machines, there’s actually a handful of various sensors seen both in older and newer systems, including those that do not indicate “possessing” one at all.

The main types of washing machine sensors and why they’re important are as follows, including “alternatives” to ones not considered to be, or necessary to have a “sensor”. The fact of the matter is, mostly all washers have some form or another of a “sensor”, regardless of if it’s articulated as being such:


Temperature Setting — A “sensor” seen on just about any washing machine, regardless of if you have access to viewing the stats involved with this mechanism. As far as such a “sensor” mechanism goes, that would be more of a personalized feature seen in automated, modern washers today relayed through an LED screen or other visual warning system.

Water Level Sensor — Just about every washing machine has a water level sensor, because without it, it would overflow and ultimately destroy itself. Some newer machines have a feature to show the currently water level, and even provides options to manually override the requirements—similarly to how you select the temperature or load size on your washers control knob. Likewise, washers designed with this features can rely on air pressure or changes to determine when to stop filling—“without a sensor”.

Dirt Sensor — The dirt sensor is a newer, and significant sensor because if there’s a major dirt build up it can not only interfere with air pressure tubes and sensors, but also be counterproductive to the system of cleaning your clothes and linens effectively.

Pin out of Balance Sensor. Nearly all washers have a pin out of balance sensor to read the balance of your pin to ensure consistent operation and prevent self-inflicted damage to the drum.

Leak detector — A considerably newer feature, washing machines can be designed with a leak detector so you know when it’s necessary and time to have your washer examined for leaks so you don’t destroy your home, or the washer itself.

Mains Failure Sensor. Lastly a mains failure sensor will indicate main or cable terminal blockage—very significant to the maintenance, as well as making sure your washer lasts as long as possible over the years.


Washer water pressure sensor shut off

Today’s modern washing machine typically operates on the ‘sensor’ technology of air pressure, based off of the water level control (WLC) mechanism found inside of your washer.


There are typically 3 air-flow and contact terminals in which work conjointly to relay necessary opening/closing of the valves and trigger water-disbursement as necessary—or to the desired “fill”.

When a washing machine is at rest, the open air valve leading to the open air dome on the outside of your washer should be closed—as it’s not necessary to disburse air since none is being collected. However, when the washing machine is being used, this terminal and hosing is open to release the air pressure built up inside of the washer, once it’s communicated a ‘full’ status to its internal computer.

Thanks to the water pressure that accumulates when you first turn your washer on to cycle, This air pressure is then relieved into an air hose and goes through a sensor before leaving the washer that tells the washer when to release or change cycles, as well as when to stop filling—as to prevent overflow.

Internal and electrical sensors known as diaphragms are the physical modules both inside—and sometimes outside—of your washer that communicate with one another to cycle through the modes, sense air pressure, water pressure, and even depth.

Given these three terminals and the air tubes involved in a typical washing cycle, it becomes more evident that air pressure is essential when responding to an internal sensor or physical pressure gauge that relays when your washer has reached the desired fill capacity—based on the settings you choose within the settings knob prior to operation.
