Samsung Dishwasher OE (1E) Error
What it means
OE stands for 'Overflow Error' — the dishwasher senses more water in the tub than there should be, usually because it isn't draining properly. On some Samsung models the same fault shows as 1E instead of OE; both mean water is backing up. Most of the time the cause is a clogged filter, sump, or drain path rather than a serious part failure, so it's often fixable at home. The dishwasher stops the cycle to avoid a leak until the excess water can drain.
Common causes of the OE (1E) error
- Clogged fine filter or sump full of food debris
- Blocked or kinked drain hose
- Drain pump obstructed by glass, debris, or a foreign object
- Garbage-disposal knockout plug left in place after installation
- Drain hose pushed too far into the disposal or standpipe
- Faulty water-level or overflow sensor
How to fix the Samsung Dishwasher OE (1E) error
- 1Power off and resetTurn the dishwasher off at the breaker or unplug it for about 5 minutes, then restore power. This clears the code if the sensor was tripped by a temporary glitch.
- 2Clean the filter and sumpOpen the door and find the filter assembly in the center of the tub floor. Rotate the filter handle counterclockwise, lift out the filter and the flat micro filter beneath it, rinse them under running water, and wipe out any debris sitting in the sump (the lowest point of the drain).
- 3Check the drain hoseMake sure the drain hose isn't kinked, pinched, or clogged. Confirm it isn't pushed too far into the disposal or standpipe, which can siphon water back into the tub.
- 4Confirm the disposal plug was removedIf the dishwasher drains into a garbage disposal, verify the disposal's knockout plug was removed during installation — a forgotten plug blocks all drainage and triggers OE.
🧰 When to call a professional
If OE (or 1E) returns after you've cleaned the filter and sump, cleared the drain hose, and reset power, the drain pump or the water-level sensor may have failed. Accessing the pump or sensor means removing panels and the lower spray arm, so call Samsung Support or a qualified technician.
Samsung OE (1E) error — FAQ
What does the OE code mean on a Samsung dishwasher?
OE means 'Overflow Error' — the dishwasher detects too much water in the tub, usually because it isn't draining. The cycle stops to prevent a leak until the water can clear.
Is the 1E code the same as OE?
On many Samsung models, yes. 1E is an alternate display of the same overflow/drain fault. The causes and fixes are the same.
How do I fix the OE error myself?
Most OE errors clear after cleaning the fine filter and sump, confirming the drain hose isn't kinked or clogged, and resetting power. If it returns, the drain pump or sensor likely needs service.
