The previous answer provided by Celene in the above response correctly identifies the OE code as indicating that you have a drain system problem in the washer. Here is another link for that previous answer:

I recommend that you check the large item filter in the drain pump for a clog or restriction. The first image below shows how to drain the sump of the washer. If the tub is still full of water, you may drain a large amount of water out of the washer using this method. If the washer door is unlocked, you can open the door and use a wet/dry shop vacuum to drain most of the water out of the washer. After the washer is drained, pull the large item filter out of the drain pump and check it for lint or debris that could be preventing the washer from draining properly. If you find no problem there and the drain pump is running during that portion of the cycle, then that component (drain pump) will likely need to be replaced. The part number for the drain pump assembly on this washer depends on the serial number. Before serial number 608KW##00001, the part number for the drain pump assembly is 585ER1002B. After that serial number, the drain pump assembly is part number 5859ER1002C. You can order these pump assemblies from the RepairClinic.com website. I do not see them available from Sears PartsDirect.com. If the pump motor/impeller just needs to be replaced and the pump housing is still okay, you can order the motor/impeller assembly from the Sears PartsDirect.com website. Here is a direct link for that part:
NOTE: Be sure that you
unplug the washer
before accessing internal components.
The second image below provides access information for changing the pump assembly. This is a complicated process. I recommend that you carefully review this procedure before attempting it yourself. The spring clamp on the bellows at the front of the washer door will need to be removed. A special tool is normally needed to remove and replace this component as noted in the image below. That tool is available from RepairClinic.com. If you are not completely confident that you can safely replace the drain pump yourself, I recommend that you have a service technician complete this repair.
