When your LG washer takes too long to wash, the problem is usually a restricted water supply or a part that is slowing the fill or heating process. First, make sure both hot and cold water supply valves are fully open. Closed or partially closed valves can make the washer cycle too long or delay the start. Next, test the LG washing machine heating element for electrical continuity with a multimeter. A failed heating element can prevent the water from reaching the required temperature and cause the washing machine to take too long. If those checks pass, inspect the water inlet valve. Low household water pressure, clogged inlet screens, or a defective valve can cause the washer to fill slowly or not fill at all. Clean the screens and replace the water inlet valve if the problem continues. These checks address common reasons for a washer taking too long and a long wash cycle. Enter your model number to find the exact heating element or water inlet valve replacement part for your specific LG washing machine.
01 - Water supply valve turned off
Confirm that both the hot and cold water supply valves are fully open. If the valves are closed or partially open the washer won't fill or will take longer to start the wash cycle.
Highly Likely
02 - LG Washing Machine Heating Element
Many washers use a heating element to raise the temperature of the water entering the tub. A defective element may cause the washer to take too long to clean its load. You can use a multimeter to test the heating element for electrical continuity. If the element tests negative for continuity, you'll know the heating element is faulty and will need to be replaced.

The water inlet valve opens to allow water to enter the washing machine. If the water inlet valve is defective, the wash may fill slowly or not fill at all. The water inlet valve requires sufficient water pressure to function properly. First, check the water pressure to determine that it is adequate. If the water pressure is adequate, try cleaning the screens inside the water inlet valve hose connection ports. If the washer still fills slowly, replace the water inlet valve.
