LG Washing Machine Repair Q&A: How to Troubleshoot a Front-Loading Washer That Won't Stop Filling?
If the washing machine continues to fill with water, first confirm whether the drain hose is hung too low, causing water to flow out of the drain hose and preventing the water level in the drum from reaching the required height, thus leading to continuous filling. If the drain hose is normally positioned and no water flows from its outlet, it can be determined that there is a fault in the washing machine's water inlet system. Common causes of failure and troubleshooting methods are as follows:
1. Faulty Water Inlet Solenoid Valve
First, check if the balancing hole on the diaphragm of the water inlet solenoid valve, which balances water pressure, is blocked. If it is blocked, clear it. Then check if the spring of the solenoid valve core is corroded. If so, replace the spring to ensure the solenoid valve works properly.
2. Damaged Water Level Controller
Check if the water level controller is functioning properly. If it is abnormal, replace the water level controller.
3. Air Leak in the Control Tube of the Water Level Controller
Check for any air leaks in the control tube of the water level controller. If there is a leak, apply some 501 glue at the leaking point to seal it.
4. Faulty Programmer
Check if the circuit of the programmer controlling the water inlet solenoid valve is in a constant-on state. If it is, repair or replace the programmer.
