There could be several reasons why your LG washer is not spinning or draining water after you press the start button. Some common causes and troubleshooting steps are as follows:
Door/Lid Not Fully Closed: Many modern washers have safety mechanisms that prevent operation if the door or lid is not securely closed. Make sure the door/lid is fully closed and latched before starting the cycle.
Power Supply Issue: Check if the washer is receiving power. Ensure that it's plugged into a working electrical outlet and that the circuit breaker hasn't tripped.
Faulty Start Button: The start button itself may be malfunctioning. Try pressing the button firmly and multiple times to see if it responds. If not, it may need to be replaced.
Program Selection: Ensure you have selected the appropriate wash cycle and options. Some cycles may not include a spin or drain phase, so choosing the correct program is crucial.
Overloaded Washer: If the washer is overloaded with clothes, it may not spin or drain properly. Reduce the load size and try running the cycle again.
Drain Pump Clog: The drain pump or filter may be clogged with debris, which can prevent water from draining. Check the drain pump filter and clean it if necessary. Refer to your user manual for instructions on locating and cleaning the filter.
Drain Hose Blockage: Ensure that the drain hose is not kinked or obstructed. A blocked drain hose can prevent water from draining properly.
Faulty Drain Pump: If the drain pump is damaged or faulty, it won't be able to pump out the water. You may need to replace the drain pump.
Lid Switch or Door Lock Issue: If the lid switch or door lock is malfunctioning, the washer may not start the spin or drain cycle. A faulty switch or lock may require professional repair or replacement.
Control Board Malfunction: Electronic control boards can fail, causing various issues with the washer's operation. If other troubleshooting steps don't resolve the problem, it's possible that the control board needs to be repaired or replaced.
If you're not comfortable with appliance repairs, it's best to contact a qualified technician or LG service center to diagnose and fix the issue. They have the expertise and tools to identify the problem accurately and ensure the proper repair of your LG washer.
