Ld flashes when the water level does not change after the drain pump is on. You should be able to reset the washer by pressing the STOP button.
Here are some troubleshooting steps for this problem:
If the washer did not drain, check your drain hose and washer drain for clogging. You may need to manually remove the water from the tub.
Unplug the washer. You can access the drain pump by carefully pulling the washer forward and tilting it backward to lean it securely against the wall. Use blocks to secure the back feet from sliding if necessary. Pull the hoses off of the drain pump and check for clogs. NOTE: You may get water draining out of these hoses when you pull them off. Use a container to catch any water that drains from these hoses.
Check the drain pump for a clog or damage. If damaged, the pump will need to be replaced.
Check the wiring connections to the drain pump. A loose or broken wiring connection could prevent the pump from running.
If the washer drained properly, you could have a problem with the water level pressure switch or the hose connection from the bottom of the tub to the pressure switch on the control.
