Your Samsung dishwasher is flashing OE, 4E, or LE on the front panel and won't run. These three error codes cover most of the calls we get for Samsung dishwashers in the Orlando area, and they each mean something different. OE means the dishwasher detects too much water inside. 4E means it can't get enough water in. LE means it's detecting a leak. The fix for each is different. And a few of them you can do yourself in 10 minutes before calling a tech.
Samsung dishwasher OE error code: too much water
OE is short for "overflow." The dishwasher's water-level sensor (Samsung calls it the case break or the sump float, depending on the model) is reading higher than expected. The machine shuts down to prevent flooding under your cabinets.
Common causes, in the order we see them:
- Clogged drain pump or filter. Food, glass shards, or labels from canned goods get past the filter and jam the pump. The dishwasher fills, can't drain, and reads too much water as a result.
- Float switch stuck. The float is a small plastic piece at the bottom of the tub that rises with water level. Mineral buildup from Orlando's hard water can stick it in the "high" position, making the dishwasher think there's a flood when the water level is fine.
- Failed water inlet valve. If the valve is leaking through even when the dishwasher is off, water keeps trickling in and triggers the OE.
- Control board glitch. Sometimes the OE is a false reading from a board that needs to be reset. Cut power at the breaker for 5 minutes, then turn it back on.
What to try first: Pull the bottom rack out, twist the cylindrical filter at the bottom of the tub counterclockwise, and lift it out. Rinse it thoroughly. Look for any debris in the sump (the well underneath the filter). Clean it out. Reinstall the filter, run a short cycle on hot, and see if the OE clears.
If it doesn't, the float or the pump is your likely problem and a tech needs to take it apart. Don't keep running the cycle with an OE active. Water can end up where it shouldn't.
Samsung dishwasher 4E error code: not enough water
4E (sometimes shown as 4C on newer models) means the dishwasher can't get water into the tub fast enough. It monitors the fill cycle, and if the water doesn't reach the right level within a set time, it throws this error.
Common causes:
- Closed water supply valve. The shutoff under the sink got bumped or partially closed during cleaning. Verify it's fully open.
- Clogged inlet filter screen. There's a small mesh screen where the water line connects to the dishwasher's inlet valve. In Orlando's hard-water area, mineral deposits, rust particles, and sediment clog this screen faster than in softer-water regions. This is the #1 cause of 4E we see.
- Kinked or partially blocked supply line. The flex hose from the shutoff to the dishwasher can develop an internal kink or crud buildup that slows water flow.
- Failed inlet valve. The solenoid that opens to let water in has burned out or seized. The dishwasher commands water flow, the valve doesn't open, the fill cycle times out.
- Low water pressure to the house. Less common, but worth checking. Your kitchen faucet should fill a 1-gallon container in under 60 seconds with both hot and cold open. If it's slower, you have a house-side pressure issue.
What to try first: Disconnect power at the breaker. Turn off the water supply under the sink. Disconnect the supply line at the back of the dishwasher (have a towel ready, water will leak). Look for the inlet filter screen. It's a small disc with a fine mesh. Clean it under running water with an old toothbrush. Reconnect, restore power, run a cycle.
If the screen was clean to start with, the inlet valve is probably bad and needs replacement. Check out our guide on DIY vs pro decision.
Samsung dishwasher LE error code: water leak detected
LE is the most serious of the three. The dishwasher's leak sensor (a small probe in the base) is detecting water where it shouldn't be. Some models will refuse to operate at all until the leak is resolved, which is a safety feature, not a defect.
Common causes:
- Actual leak from a hose, gasket, or pump seal. Pull the dishwasher out and look underneath. If you see water or moisture, you've found it.
- Failed door gasket. If the gasket is cracked or warped from age, water sprays out during the wash cycle and pools at the bottom.
- Cracked tub. Rare, but it happens. Usually on dishwashers older than 10 years that have been moved or shifted.
- False reading from a wet leak sensor. If a small spill happened months ago and the sensor is sitting in residual moisture, it can keep reading "leak" even after the original issue is dry. Drying the sensor can clear it.
What to try first: Stop using the dishwasher. Pull it out from the cabinet and put towels under the base. Tip it forward 30 degrees for 10-15 minutes to drain any residual water. Wipe the leak sensor (a small white disc at the bottom) dry. Reset by cutting power for 5 minutes. Run a short cycle and watch the floor under and behind the dishwasher.
If the LE comes back, you have an actual leak and a tech needs to find it. Don't keep running the dishwasher with a real leak active. Check out our guide on more on dishwasher leaks. Under-cabinet damage gets expensive fast.
What Samsung dishwasher repairs typically cost
Industry averages from Yale Appliance's 2025 service-call data put dishwasher repairs in the $140-$400 range, with an average around $180. Check out our guide on appliance repair cost in Orlando. Samsung dishwashers tend to fall in the middle of that range for the common error-code repairs (filter clean, inlet valve replacement, gasket swap). Premium Samsung models with smart features (Family Hub-connected, etc.) can run higher because the control boards are more complex and parts are pricier.
We carry the most common Samsung parts on our trucks, including inlet valves, drain pumps, and door gaskets for the most popular models. Check out our guide on if your dishwasher isn't cleaning properly. That usually means a single-visit repair for the OE / 4E / LE codes.
Common questions about Samsung dishwasher error codes
Why does my Samsung dishwasher keep showing OE even after I cleaned the filter?
The float switch may be stuck or the inlet valve may be leaking through. Cut power at the breaker for 5 minutes to reset the control board first. If OE returns, it's likely a hardware issue that needs diagnosis.
Is the 4E error the same as 4C on Samsung dishwashers?
Yes. Samsung used 4C on newer models and 4E on older ones for the same water-supply issue. Both point to the dishwasher not getting enough water during fill.
Can I run my Samsung dishwasher with an LE error?
Don't. The error means it's detecting water somewhere it shouldn't be. Running the cycle can cause cabinet and floor damage that's far more expensive to repair than the dishwasher itself.
How do I reset a Samsung dishwasher?
Power-cycling at the breaker (off for 5 minutes, then on) is the most reliable reset. Some models have a sequence on the front panel, but the breaker reset works on every model.
Are these error codes specific to certain Samsung dishwasher models?
OE, 4E, and LE appear across most Samsung dishwasher lines from roughly 2010 onward. Newer models may also display 4C, OC, or LC for the same conditions. The troubleshooting is identical.
