Samsung Dishwasher OE (1E) Error
What it means
OE is an over-level water error โ the dishwasher senses more water in the tub than there should be, usually because it isn't draining properly. Samsung shows the same drainage fault as 1E on many models (and as OC or 0C on others); on WaterWall dishwashers Samsung explicitly groups 1E and OE together as a blockage preventing the unit from draining. 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.
The bottom line on the OE (1E) error
OE โ the same fault Samsung shows as 1E, OC, or 0C โ is an over-level water error, and it usually means the drain path is blocked: a clogged filter, a full sump, or a kinked hose, not a failed part. Resetting alone will not help; the code returns until the blockage is cleared.
Start free by cleaning the filter and sump and clearing the drain hose, then reset power โ Samsung says this clears most OE/1E faults. Only if it returns has the drain pump or level sensor likely failed; that $130โ$320 repair is worth it on a dishwasher under 7 years.

Water plus electricity โ before removing panels to reach the pump or sensor, unplug the dishwasher (or switch off its breaker) and shut off the water supply.

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
Which Samsung dishwashers get the OE (1E) error
OE โ with its equivalent 1E, OC, and 0C displays โ appears across Samsung's DW60, DW80, and DW50 built-in and freestanding dishwasher lines, including WaterWall models, from roughly the mid-2010s onward. All use a water-level/overflow sensor, and the fault points to a drainage blockage rather than a specific model defect.
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). Samsung notes this clears most 1E/OE drainage faults.
- 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 โ a forgotten plug blocks all drainage and triggers OE.
๐งฐ 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.

How much does it cost to fix the OE (1E) error?
| DIY (clean filter, sump, drain hose) | Free |
| DIY parts (drain pump or sensor) | $25โ$90 |
| Professional repair (parts + labor) | $130โ$320 |
| New dishwasher replacement | $600โ$1,700 |
Repair or replace?
OE is usually a free fix โ a clogged filter, sump, or drain hose is the cause the large majority of the time, so always clean the drain path before paying for anything. If the drain pump or water-level sensor has genuinely failed, the part is modest ($25โ$90) but reaching it means pulling panels; a technician visit runs about $130โ$320. On a dishwasher under roughly 7 years old that repair is worth it, but if the machine is older and the quote approaches half the price of a new unit, replacement makes more sense (prices vary by model and region).
Common replacement parts for the OE (1E) error
| Drain pump | $40โ$90 | If water won't drain after the filter and hose are clear | |
| Water-level / overflow sensor | $25โ$70 | If OE returns with a clean, unobstructed drain path | |
| Fine filter assembly | $15โ$40 | If the filter is damaged rather than just dirty |
Prices are typical retail ranges and vary by model and supplier โ always confirm the exact part number for your appliance before buying. We are not linking parts for this code on purpose: it is a job for a qualified technician, and the right fix here starts with a diagnosis, not a purchase.
Samsung OE (1E) error โ FAQ
๏ผ โ What does the OE code mean on a Samsung dishwasher?
OE is an over-level water error โ 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. Some panels show the same fault as OC or 0C.
๏ผ โ Is the 1E code the same as OE?
On many Samsung models, yes. Samsung groups 1E with OE as a drainage blockage โ 1E means water isn't passing through the fine filter. The causes and fixes (clean the filter, sump, and drain path) are the same.
๏ผ โ 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.
