Samsung Washer 0E Error Code — What It Means & How to Fix It

What Does This Error Mean?

The 0E error on a Samsung washer means the machine has detected too much water in the drum — it is overflowing or overfilling. The washer stops the cycle to prevent water from spilling onto your floor. This typically happens because of a faulty water inlet valve that won't fully close, a failed water level sensor, or a drain hose that is siphoning water back in. You may see water above the door glass level, a wet laundry room floor, or the washer repeatedly filling and draining.

Affected Models

Samsung WF45R6100AW
Samsung WF42H5000AW
Samsung WA40J3000AW
Samsung WF56H9100AG
Most Samsung front-load and top-load washers

Common Causes

Faulty water inlet valve not fully closing when the machine tells it to stop
Defective water level pressure sensor giving incorrect readings to the control board
Drain hose installed too low, allowing water to siphon back into the drum
Blocked or kinked pressure hose connected to the water level sensor
Control board fault causing incorrect water level signals to the inlet valve

How to Fix It

Turn off the water supply to the washer immediately — there are two hoses (hot and cold) connected to the back of the machine. Turn the valve handles clockwise to shut off the supply.

Stopping the water supply prevents further overflow while you diagnose the problem.
Check the drain hose position. The end of the drain hose must be at least 30 inches above the floor and inserted no more than 6 inches into the standpipe. A hose that sits too low can siphon water back in.

Consult the installation guide for the correct drain hose height for your model.
Inspect the pressure tube — a small plastic or rubber hose that connects from the tub to the water level sensor. Make sure it is not kinked, cracked, or disconnected.

A blocked pressure tube makes the sensor think the drum is less full than it is, causing the valve to keep adding water.
Test the water inlet valve. With the washer unplugged, remove the inlet valve and test each solenoid coil with a multimeter. A coil that does not close when de-energized will let water seep through constantly.

Inlet valves typically cost $30 to $80 and are a common repair on overflowing washers.
If the drain hose position and inlet valve are both fine, the water level pressure sensor may need testing or replacement. This is best confirmed by an appliance technician.

Pressure sensors on Samsung washers are usually $20 to $50 for the part.

When to Call a Professional

Water overflows can quickly cause floor damage, mold, and structural problems. If you are not sure how to replace a water inlet valve or pressure sensor, call an appliance technician. A technician can use a multimeter and pressure gauge to confirm which component is faulty before parts are ordered. Samsung authorized technicians can also run a diagnostic cycle to pinpoint the fault.

Frequently Asked Questions

Is 0E the same as OE on a Samsung washer?

They look very similar on a digital display. On Samsung washers, the number zero (0E) and the letter O (OE) can appear identical. Both refer to overflow or over-level water conditions and have the same causes and fixes. Check your model's manual to confirm which code your display is showing.

Will the 0E error damage my washer?

The 0E error itself is a safety stop — the machine is working correctly by stopping to prevent a flood. However, the underlying cause (a stuck-open inlet valve) can continue to let water in even with the machine off. Always shut off the water supply lines when you see this error to prevent floor damage.

How do I reset the 0E error?

Fix the underlying cause first, then unplug the washer for 5 minutes. When you plug it back in, the error should clear. Do not simply reset the error without fixing the root cause — the washer will overfill again.
