1. Fault manifestation
The washing machine cannot stop filling water automatically: When the water level sensor of the front-loading washing machine fails, one of the most obvious manifestations is that the washing machine cannot stop filling water automatically. The water level sensor is an important component responsible for monitoring the water level inside the washing machine. Once it cannot accurately sense the water level information, the washing machine cannot stop filling water after reaching the set water level. This will cause the water level in the washing machine to continue to rise, which may eventually cause water overflow, causing damage to the washing machine or dampness in the home environment.
The washing machine cannot adjust the water level: In addition to being unable to stop filling water automatically, a water level sensor failure may also cause the washing machine to be unable to adjust the water level. During the washing process, the washing machine needs to adjust the water level according to the weight and type of clothes. If the water level sensor does not work properly, the washing machine cannot accurately sense the internal water level, and thus cannot make effective water level adjustments. This will affect the washing effect and may even cause the washing machine to be overloaded or damaged.
The washing machine cannot drain: After the washing is finished, the washing machine needs to drain the water inside. However, when the water level sensor fails, it may not be able to accurately monitor the water level inside the washing machine, resulting in the washing machine being unable to drain normally. This will cause the water inside the washing machine to be unable to be effectively discharged, which in turn affects the normal use of the washing machine.
Washing machine error code: Many modern front-loading washing machines are equipped with advanced fault detection systems. When the water level sensor fails, the washing machine may display specific error codes, such as E1, E2 or E6. These error codes can help users or maintenance personnel quickly identify the problem and take appropriate repair measures.
Washing machine leaks: Since the water level sensor cannot accurately sense the water level inside the washing machine, this may cause the washing machine to leak during the filling or drainage process. Leakage not only wastes water resources, but may also cause damage to the home environment, such as damp floors and water seepage in walls.

2. Repair method
Check and clean the filter: The filter under the washing tub impeller may accumulate a lot of dirt and debris due to long-term use, causing blockage. When the filter is clogged, it will affect the normal water circulation inside the washing machine, thereby affecting the normal operation of the water level sensor. Therefore, the filter can be removed and cleaned to ensure unobstructed water flow.
Check and reconnect the line: The connection line between the water level sensor and the washing machine computer board may be loose or in poor contact. This will cause the water level sensor to be unable to transmit accurate water level information to the computer board, thus affecting the normal operation of the washing machine. Therefore, you can check whether the line connection is firm and reconnect the line to ensure its normal operation.
Replace the water level sensor: If the water level sensor itself is found to be faulty after inspection, such as damage or aging, then you need to replace it with a new water level sensor. When replacing it, you need to select a water level sensor that matches the model and specifications of the washing machine and install it according to the instructions or the guidance of professionals.
Check and repair the computer board: If there is no problem with the connection line between the water level sensor and the computer board, but the washing machine still does not work properly, it may be that the detection circuit of the computer board is faulty. At this time, you need to check and repair the computer board to ensure its normal operation. When repairing, you need to be careful not to damage other components and circuits on the computer board.
Check and replace screws: Sometimes, the screws inside the washing machine may become loose or slip due to long-term use. This will cause the internal structure of the washing machine to be unstable, thus affecting the normal operation of the water level sensor. Therefore, you can check and replace the screws inside the washing machine to ensure that they are firm and reliable. When replacing it, you need to select screws that match the model and specifications of the washing machine and install them according to the instructions or the guidance of professionals.

Temperature Sensor

Front Load Washers have several important parts that work together to clean and dry clothes. These include the metal drum, door seal, door lock, dispensers, control panel, and motor. The metal drum is the container that holds the clothes and agitates them during the wash cycle. The door seal helps to keep water inside the drum during the wash cycle. The door lock prevents the door from being opened during the wash cycle. Dispensers are where you add detergent, fabric softener, and other laundry products. The control panel allows you to select wash cycle options and monitor the progress of the wash. The motor powers the drum and other parts of the washing machine.
