LG dishwsher will not drain. error Code OE

I have completely cleaned the drain assembly inside the DW. I have completely cleaned the entire drain hose. I disconnected the drain house at the sink air vent and ran DW, still won't drain. I disconnected the wire assembly to the drain pump and hooked up to power, it works. I replaced the main PCB, still won't drain. Any suggestions? Thanks

If the water doesn't drain from your dishwasher, check these:

Drain line/air gap A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.

Pump Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support. 

Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.

Drain valve and/or solenoid Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water. 

Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing.

Belt One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.

Motor If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced. 

Some dishwashers are susceptible to getting stuck if you don't run them regularly. If you haven't run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can't be serviced.

Timer Part of what the timer does is control the motor and drain valve. If the timer doesn't work properly, the water may not drain and you need to replace the timer. This problem is uncommon.

What is Oe error lg model lds5540st


The OE error or fault code to indicate that the washing machine is not draining properly. Check to be sure the drain hose isn't clogged or kinked. If that checks out, check to see if the drain pump or drain pump filter are clogged. Sometimes objects that are put into the washing machine, for example combs, money, hair pins, etc. end up in the filter. Finally, if the drain line is clear and the pump seems to be clear and functioning properly, you may need to replace the drain pump assembly.

Oe code. Will not drain. Steps to fix?


Hi

OE in your dishwasher is a drain error and dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. If the issue returns after cleaning then the drain pump assembly should be replaced. Hope this helps...please post back for further assistance.

Oe error...manual says clogged but cant find clog


It is important to start where the drain hose connects to the drain. Probably connects indirectly to the garbage disposal. Look for blockage there and work your way back to the dishwasher.

IF you can't find a blockage, then it is time to remove your lower spray arm and the approximately 9 screws that secure the filter assembly to the sump floor. Rinse everything that you remove.

Using a flashlight, inspect the entire sump area for debris (watch out for broken glass!) Look closely where the drain pump is located. You will probably find some sort of blockage jamming that pump.

Reassemble and test. It is rare, but an OE error could be created by a failing drain pump motor. But try everything else first.

Good Luck!

Measure the electric resistance of the Drain Motor. (Value should be 20-40 Ohms) If it is out of spec, replace it.

Lg - LDS5811ST Dishwasher OE Error Code


hi
The most common cause of an OE error code on a modern LG dishwasher is:
1. Blocked drain hose
2. Obstruction in the sump area (beneath the filter, which needs to be removed to check for onstruction)
3. Failing drain motor. 
else you need to REPLACE THE PCB POWER CONTROL BOARD
