LG Dishwasher Error Code OE – DRAINING ERROR – How To Fix

The Most Common Cause for OE ERROR CODE = DRAIN ERROR. This means the water is not draining out of the dishwasher as designed. LG has given this error/fault code to show an issue with the dishwasher water drain pump. First, inspect the drain hose for a clog or bend. Second, inspect the dishwasher drain pump for any blockages in the pump housing assembly. Clean any and all blockages and the OE error code should clear. Also check the FLOAT SWITCH inside the LG dishwasher for obstructions.

MORE DETAILED FIX FOR LG DISHWASHER WITH OE ERROR CODE:
An LG Dishwasher that displays the OE error indicates a DRAIN ISSUE. This means when the LG dishwasher gets to the time for it to drain out water, it is not draining correctly or cannot drain. This is caused by a CLOGGED DRAIN HOSE or a CLOGGED OR FAULTY DRAIN PUMP.

The most likely reason an LG dishwasher shows the OE error is the DRAIN HOSE IS BENT, CLOGGED, OR NOT POSITIONED PROPERLY.
– Be sure the Dishwasher Drain Hose on your LG washer is not bent/kinked.
– Check that the Dishwasher Drain Hose is not clogged with food particles.
– See if the Dishwasher Drain Hose may not be draining if the wall drain is blocked/clogged.
– Make sure the Dishwasher has either a HIGH DRAIN LOOP or AIR GAP installed. (without one of these, the dishwasher may drain but will usually leave WATER IN BOTTOM OF DISHWASHER)
– If you find the Dishwasher Drain Hose to be damaged in any way, remove and replace it.

The part that is most likely to be faulty (or blocked/clogged) is the Dishwasher Drain Pump.
– Make sure the Dishwasher Drain Pump has nothing blocking it in the pump housing assembly.
– Examine the Dishwasher Drain Pump for damage such as cracks and breaks.
– After thoroughly checking the Dishwasher Drain Pump and the error code comes back then the Drain Motor Pump Assembly may need to be removed and replaced.

Checking the drain hose (depending on how the dishwasher is installed) will involve removing the Drain Hose from the bottom of the dishwasher and visually inspecting it.

Examining the drain pump will involve removing all dishwasher racks and checking down in sump to be sure nothing is blocking the drain. If all clear, the drain pump will need to accessed to see if food, foreign objects or broken glass is blocking it.

  1. I have an lg ld2131 dishwasher. I switch on and it proceeds to drain. There is no water left in the dishwasher but drain function just keeps going – won’t let in water – there is adequate water pressure – checked there is no blockage before inlet valve or in inlet valve, no leaks that has activated the inlet valve floater, when taking out inlet valve and connecting power it opens and let’s water in. Checked nothing stuck inside dishwasher as it drains. Can’t seem to find a floate switch inside the dishwasher. Swopped main board still nothing. Checked and replaced all hoses. What am I missing?

  2. Same here. Bottom of dishwasher full of dirty water. This dishwasher is not more than 1 year old. I’m not thinking LG is the greatest purchase in the future. I already pulled the machine out from under my counter (not an easy job) and checked to make sure the hose was not clogged. I blew high compressed air through the hose. Those did not do any good.

  3. That’s funny have identical problem went thru all the steps drain pump wasn’t clogged and worked before wash cycle but changed anyway cheap part no fix checked drain hose for clogs none found didn’t change hose but found back flow valve in drain hose distorted which would let water back into washer anyway dishwasher does same thing drains in beginning goes thru wash cycle and then no drain oe fault sucks let me know if u figured this out!

  4. I have an LG dishwasher, that is not draining when running but it does drain at the beginning when you first shut the door. I have replace the drain pump made sure the line was not clogged or bent. I have checked inside the dishwasher to make sure the sensors clean and that the drain is not clogged inside the machine. I will start the washer and it will drain start to run and then when the first run cycle finishes it goes back to the I have checked inside the dishwasher to make sure the sensor is clean and that the drain is not clogged inside the machine. I will start the washer and it will drain start to run and then when the first run cycle finishes it goes back to the OE code

  5. My washing machine is randomly flashing lights on the display and did not start. What would have caused this.
    Thanks.
