OE
LG OE on a dishwasher: the tub is not fully draining
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On an LG dishwasher, OE means the tub has not fully drained. LG points mainly to food clogs and to how the drain is installed. Start by removing debris from the bottom and cleaning the filter below the spray arms.
Safety first
Stop and check this first
- Switch the dishwasher off before reaching into the tub for debris or the filter: there is water next to a mains powered appliance and there may be sharp objects at the bottom.
Safe checks you can perform
- Filter and debris at the bottom of the tub
- Drain hose under the sink
- Air gap or disposal
Leave these tasks to a qualified professional
- Do not attempt this professional task: Drain test after the repair
- Do not attempt this professional task: Drain circuit check
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Drain test after the repair
What they doThe technician runs a full cycle and checks that the tub empties without OE returning.
They must show youa full cycle with no water left and no code.
In writingthe test, the result and the date.
Drain circuit check
What they doWith the unit disconnected, the technician checks the drain pump, its connection and the sump, and checks the installation against LG measurements (12 feet maximum length, 12 inches minimum height).
They must show youwhat they found and the measurement against the LG specification.
In writingwhat was checked, the result and the reference of any replaced part and why.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Filter and debris at the bottom of the tub
- Who:
- you, no tools.
- How:
- remove the lower rack, take out large debris, turn the mesh filter counterclockwise, wash it with warm water and something non-abrasive and refit it. Then run an empty HEAVY DUTY or NORMAL cycle with no detergent, as LG says.
- Result that matters:
- water drains and OE does not return in that cycle.
- If the filter had debris and the empty cycle ends without OE:
- it was a clog; LG recommends cleaning the filter after each load for best wash performance.
- If the filter was clean and OE returns:
- the problem is in the hose or the drain connection.
- Evidence to keep:
- a photo of the filter before and after cleaning.

Drain hose under the sink
- Who:
- you, no tools.
- How:
- with the unit off, follow the corrugated hose (white, gray or opaque) from the dishwasher to the drain and look for bends or crushed sections. Straighten it and run a test cycle.
- Result that matters:
- a straight hose, not pinched, with its high section at least 30 cm above the floor, as the LG guide asks.
- If it was kinked and drains once straightened:
- that was the cause.
- If it is straight and correctly placed:
- check the air gap or the disposal.
- Evidence to keep:
- a photo of the hose along its route.

Air gap or disposal
- Who:
- you, if the drain runs through an air gap or a disposal.
- How:
- remove the air gap cover, clear debris with a toothpick or brush and flush with hot water. If the disposal is new, check whether the dishwasher inlet knockout plug was removed.
- Result that matters:
- a clear drain connection.
- If there was debris or the plug was still in and it now drains:
- that was the cause; LG suggests an empty cycle with vinegar or dishwasher cleaner.
- If everything was clean and OE persists after forcing a drain:
- request a repair.
- Evidence to keep:
- photos of the connection and the installation date if recent.

What it means
LG defines OE on a dishwasher as an outlet error: the unit detects that the tub has not fully drained. Its OE guide lists food clogs in the filter and spray arms as the most common origin, then installation: a kinked or pinched drain hose, a clogged air gap or in-sink disposal, a hose longer than 12 feet or a disposal knockout plug left in. The code does not point to the drain pump: if all of that is fine and it persists, a repair is needed.

Symptoms and causes
Probable causes · in order
- Clogged filter or spray armsCommon
LG lists it first. You can tell when you take the filter out: if it has debris and the unit drains after cleaning and an empty cycle, that was it.

- Kinked or pinched drain hoseCommon
Visible under the sink: a crushed or bent corrugated hose. If the test cycle drains once it is straightened, that confirms it.

- Clogged air gap or disposalPossible
If the drain runs through an air gap or a disposal, LG asks you to check them. It stands apart because the hose is fine but the connection point has debris.
Evidence: LG USA dishwasher OE troubleshooting
- Incorrect new installationPossible
Only on a newly installed dishwasher: a hose longer than 12 feet or extended, less than 12 inches (305 mm) high from the base, or the disposal knockout plug not removed.
