Dishwasher water leakage is a common failure phenomenon in daily use, and its essence is that the integrity of the equipment sealing system or the waterway system is destroyed. Timely and accurate identification of the cause of water leakage and take correct disposal measures can effectively prevent further damage to equipment and kitchen property losses. The following will systematically analyze five common causes of water leakage and their corresponding solutions.
1. Door seal problem
The door seal is the key seal between the dishwasher door and the inner container. Its aging, damage or contamination of foreign matter will cause the seal is not tight, when washing from the door leakage.
Solution: Clean the door seal with a damp cloth regularly to ensure that there is no foreign matter. If the seal is found to be aging, cracking or losing elasticity, you should contact the after-sales service to replace the original parts.
2. Filter clogging
The filter is used to intercept food debris. If it is not cleaned for a long time, it will cause serious blockage, which will hinder the normal discharge of water flow, causing the internal water level to rise and overflow from the door crack.
Solution: regularly remove the bottom of the filter, rinse with water to ensure smooth drainage.

3. Spray arm damaged
The spray arm sprays water to wash the dishes while rotating. If the shaft sleeve sealing ring is aging, the spray arm itself is broken or the installation is not in place, the water will leak from the connection.
Solution: check whether the spray arm crack, rotation is smooth. If it is damaged, replace it. Always make sure that it snaps into place during installation.
4. Inlet valve fault
The water inlet valve controls the entry of water. If the valve is not closed tightly or internal failure, it will cause continuous or intermittent slow water intake, and eventually cause internal overflow.
Solution: If it is found that the dishwasher also has water inlet sound during non-working hours, it is likely that the water inlet valve is faulty and needs to be detected and replaced by professional maintenance personnel.

5. Drain or hose aging
The drain hose connected to the dishwasher may age, crack or be squashed and kinked after long-term use, resulting in poor drainage or direct water leakage.
Solution: check the drainage pipe for visible damage or excessive bending. If there is a problem, replace the drain pipe with a new one and ensure smooth installation.
6. Drainage pump fault
The drainage pump is responsible for discharging the sewage after washing. If the pump body seal ring is damaged or the pump itself is cracked, leakage will occur during drainage.
Solution: drainage pump failure usually requires professional judgment. If water leaks at the bottom of the machine and is accompanied by abnormal drainage noise, contact maintenance personnel to check the drainage pump.
7.Improper installation
Dishwasher installation is not level, the door is not leveled or the connection of the inlet and outlet pipes is not tight, will bury the hidden danger of water leakage.
Solution: check whether the machine is stable, whether the door is tightly closed, and whether all water pipe interfaces are fastened. If necessary, ask the installer to re-debug.
8.Damaged tank or water tank
The weld of the dishwasher liner is cracked, or the plastic water tank is cracked due to aging and external impact, which will cause serious water leakage.
Solution: found that the inner tank water should be immediately shut down power. The repair of inner tank damage is very professional, do not handle it yourself, and contact the after-sales service center immediately.

Conclusion
Facing the problem of water leakage in dishwashers, it is suggested to give priority to daily maintenance links such as door seal cleaning and filter screen washing, and gradually extend the investigation to internal components such as drainage pipes and water pumps. Regular maintenance can significantly reduce the risk of water leakage. If you encounter a fault that cannot be judged or resolved by yourself, you should contact professional maintenance personnel for processing in time to ensure the repair effect and safe use.
