Do you need assistance with your LG washing machine? A common problem might be a malfunctioning level sensor. This tiny but essential part helps your machine calculate the appropriate water flow for each load. When it breaks down, you may observe issues such as improper water levels or even the washing cycle not starting.
The level sensor is not as difficult to check as it might seem. We’ll take you step-by-step through the process of diagnosing and testing the sensor in this guide. This will assist you in identifying the issue before you call a technician, saving you both time and money.
We’ll go over everything, including where to find the sensor in your computer and how to run quick tests to make sure it’s operating properly. You can resolve this common problem and restore your LG washing machine to its original functioning condition with a few simple tools and some perseverance.

Instructions for checking
There is no reason why you should climb into the machine. Prior to identifying the pressure switch issue in an LG washing machine, it’s a good idea to look for specific indications of a malfunctioning water level relay. If there are no repercussions, the breakdown is not finished, so the device will send the owner the following signals to alert them to the issue:
- the drum rotation or the inclusion of the heater without water in the typewriter occurs;
- Not enough or excessive set of tank is noticed;
- In rinsing mode, the water is pumped out and filled again;
- The smell of Gary is felt;
- The fuse is triggered on the heating element;
- no squeezing.
The presence of even one "symptom" indicates that a press start needs to be diagnosed. However, since other flawed details may contribute to these issues, you cannot solely blame the level relay for your problems. We remove the sensor and perform a performance check to rule out the error.
Having a special screwdriver with replaceable nozzles is essential because the LG washing machine manufacturer is situated close to the press start of the fasteners with unique heads, for safety reasons.
- Unscrew the two screws holding the top panel at the back of the case.
- Press the cover away from you and remove it.
- Find a round plastic box of black or white color near the side wall – this is the pressure switch.
- Disconnect the wiring and pipes from the sensor.
- Loosen the fixing bolts and pull out the housing with a long tube going into the tank.
After removing the sensor, we start the examination. We start by visually inspecting the tube to make sure there is no damage or obstructions, and that the outer lamellas on the connectors are only clean and not oxidized. If issues, oxidation, corrosion, or contamination are apparent, the relay is thoroughly cleaned and cleaned. Next, we move on to the direct examination:
- find a hose or tube proportionate to the hole of the pressure switch fitting;
- put the tube on the fitting;
- bring the unit to your ear, and the end of the hose to your mouth;
- blow into the hose and listen for a click. There are usually two or three clicks, but some models allow a single contact. The main thing is that there is no silence, which signals a faulty pressure switch.
An ohmmeter or multimeter connected to the sensor terminals is an alternative method. A sudden change in resistance should be recorded by the device if you close and open the contacts. It’s advised to first familiarize yourself with the electrical circuit diagram found in the factory instructions to avoid making any mistakes when connecting to the connectors.
Configuring the operation of the pressure switch
It is possible to attempt "reprogramming" a broken pressure switch. To accomplish this, set the two adjusting screws to a specific water level such that the central one records the closure of the contacts, and the third one records the rupture of the contacts. Given that different machine models assume different washing programs with different tank fillings, there might be multiple contact pairs in this instance. For instance, a full drum is used for a standard or delicate cycle, and only half when using the economy mode.
Trying to adjust the screw positions by yourself is very difficult. Experts at the factory perform a thorough adjustment, after which the tube is marked appropriately. It is highly advised against altering the established stance because doing so could cause a major imbalance. The fact that an average user of the machine is unaware of how much water the unit uses at each stage when activating any of the available programs complicates the situation. Reprogramming the pressure switch becomes more challenging the more modes the washing machine offers.
To make sure your LG washing machine functions properly, it’s crucial to check the level sensor. If this sensor isn’t working properly, it could lead to problems like incorrect water filling or draining because it’s vital to determining the water level in the drum. You can determine whether the sensor requires maintenance or is operating correctly by following a few easy steps.
To be safe, start by unplugging your washing machine. Next, get to the level sensor, which is usually found inside the apparatus close to the water tank. Examine the sensor and the tubes that connect it carefully for any obvious damage or obstructions. A clean, undamaged sensor is necessary for precise measurements and optimal machine operation.
Use a multimeter to test the sensor if you think it might be defective. You can verify whether the sensor is giving accurate readings with the aid of this device. It could be best to contact a professional if you don’t feel comfortable handling this yourself. Getting a professional to look at it can help you save time and ensure that your washing machine is operating at its best. Occasionally, problems with the sensor can also be related to other components.
You can prolong the life of your washing machine and avert more serious issues later on by taking care of your level sensor and fixing problems as soon as they arise. You can keep your appliance in excellent condition and prevent needless repairs by doing routine inspections and simple troubleshooting.
Verifying the level sensor on your LG washing machine could be a wise first step if you’re experiencing issues. You can make sure your washer fills with the proper amount of water by following this easy guide, which will show you how to test and inspect this important part. You can keep your machine operating smoothly and troubleshoot problems more efficiently if you know how to check the level sensor.
