What does EEPROM ERROR mean on my LG WM0742H*A Washer and how do I fix it?
If your LG Washer displays an EEPROM ERROR, it means the EEPROM is out of order and needs to be replaced.
Why is my LG WM0742H*A Washer not turning on?
Your LG washer might not turn on if the power cord is not properly plugged in. Ensure the plug is securely plugged into a grounded, 3-prong, 120-VAC, 60-Hz outlet. Another possibility is a blown house fuse, a tripped circuit breaker, or a power outage. Reset the circuit breaker or replace the fuse, without increasing the fuse capacity. If the problem is a circuit overload, have it corrected by a qualified electrician.
What to do if my LG Washer door will not unlock?
If the door of your LG washer won’t unlock after stopping or pausing a cycle, it could be due to a couple of reasons. The interior temperature of the washer might be too high; the washer door has a safety lock to prevent burns, so allow the washer to cool until the DOOR LOCK indicator turns off. Alternatively, the water level in the washer might be too high; allow the washer to complete the programmed cycle, or run the DRAIN & SPIN cycle to drain the water.
Why won't my LG WM0742H*A spin?
Your LG washer may not spin if the door is not closed properly. Make sure that the door is closed properly and press the START/PAUSE button. After starting a cycle, it may take a few moments before the drum begins to turn or spin. The washer will not spin unless the door is locked (DOOR LOCK will appear in the display). If the door is closed and locked and the open door error message is displayed, call for service.
How to fix a DRAIN ERROR on my LG WM0742H*A?
If your LG Washer displays a DRAIN ERROR, it means the water hasn't fully drained within 10 minutes. Check for any clogs in the drain hose or pump.
What does HEATING ERROR mean on my LG Washer?
If your LG Washer is showing a HEATING ERROR, the THERMISTOR might be out of order. Inspect and replace the THERMISTOR if necessary.
What causes an OVER FLOW ERROR in my LG Washer?
If your LG Washer displays an OVER FLOW ERROR, it indicates that the water is overflowing because the water level frequency is too high. Ensure the drain pump is functioning properly so that it can drain the water automatically.
What to do if my LG WM0742H*A experienced a POWER FAILURE?
If your LG Washer is not working because of a POWER FAILURE, check the power supply and ensure the washer is plugged in.
Why is my LG WM0742H*A Washer wash cycle time longer than usual?
The wash cycle time on your LG washer may be longer than usual because the washer automatically adjusts the wash time based on the amount of laundry, water pressure, water temperature, and other operating conditions. This is normal, as the washer adjusts cycle time automatically to provide optimal results for the selected cycle.
Why is my LG WM0742H*A making a vibrating noise?
A vibrating noise in your LG washer can occur for several reasons. It could be due to shipping bolts and packaging materials not being removed during installation, an unevenly distributed wash load, leveling feet not resting firmly on the floor, or the floor not being rigid enough. To address this, check the installation instructions to ensure all shipping bolts and packaging have been removed. Stop the washer and rearrange the wash load if it's uneven. Adjust the leveling feet to ensure all four are in firm contact with the floor during the spin cycle. Finally, ensure the floor is solid and doesn't flex.
