Samsung washer error codes are essential to understand as a part of the appliance repair industry. Samsung washer codes tell you what problem your machine has detected. It ranges from water fill and drain issues to door lock or load imbalance faults.
You can often fix simple issues yourself without unnecessary service visits when you know what a code means. Thus quickly getting your laundry back on track. This guide covers both front-load and top-load Samsung washers.
This guide will help you decode messages from both means. This means whether they show on a digital display, via blinking lights, or through Smart Care diagnostics. Samsung washers display codes on the control panel or use combinations of blinking LEDs when there is no screen.
The error codes usually point to common problems. These problems include water not filling, draining errors, unbalanced loads, door/lid errors, or sensor faults. You will also learn how to interpret codes using Smart Care.
Samsung’s built-in self-diagnosis tool comes under Smart Care. the code is scanned or manually entered into the Samsung Smart Washer/Dryer app to get detailed meanings and suggested steps. Therefore, this guide helps you understand and respond to error codes on most Samsung washer models.
What Do Samsung Washer Error Codes Mean?
Samsung washer error codes are information codes. The error codes indicate specific issues detected by the control system of the machine. The codes help you diagnose common problems.
These problems include water supply failures (e.g., 4C, nF), drain issues (e.g., nd, 5C), and door/lid lock faults (e.g., dS, FL), etc. The washer uses this feedback to solve the problem.
Error messages are shown in three ways below.
- The digital display panel includes modern Samsung washers show codes. For example, nF, 4E, UE directly on the screen.
- Blinking lights are present in models without displays. These use specific light blink patterns to represent codes.
- Smart Care or app include scanning or inputting the error code into the Samsung Smart Washer/Dryer app. This is to get a user-friendly explanation and steps.
Check the user manual or model number to identify whether a code is for a front-load or top-load washer. Some codes, especially door/lid-related ones are model-specific even though many codes overlap.
How Do I Find the Error Code on My Samsung Washer?
Error codes appear on the control panel display. This happens when the washer detects a fault during a cycle. For example, a water fill or drain error. Models with digital screens clearly show codes such as dE, UE, or nF.
Washers without a digital display use blinking lights. The pattern and sequence of blinking means specific error conditions.
Samsung washers include a Smart Care/Self-diagnosis feature. This helps interpret error codes. Activate this by pressing the Smart Care button on the washer. Then use the Samsung Smart Washer/Dryer app on your smartphone (Android/iOS) to scan or manually enter the code. The app interprets the code and suggests steps or explanations.
Error notifications also appear directly in the SmartThings app if the washer supports Wi-Fi.
How Do I Fix My Samsung Washer Error Code?
Samsung washer error code tells you what the problem is. Many of these faults are fixed with simple troubleshooting steps without a technician. The first thing is to reset or power-cycle the washer.
Just unplug the washer or turn off the circuit breaker. Then wait 1 to 5 minutes, and plug it back in, finally, restart the cycle. This clears temporary glitches and stored error codes. The code reappears if the issue remains.
Follow the seven general troubleshooting steps below.
- Power-cycle/reset the washer. Turn off the washer, unplug it for 1 to 5 minutes, then plug it back in and restart.
- Check water supply to ensure inlet hoses are not kinked. Correct connection is crucial with water valves fully open.
- Inspect the drain hose and pump filter for clogs. Then clean if needed.
- Redistribute laundry to prevent balance errors. Open the door, even out the load, and restart.
- Door or lid check to fully close it and ensure nothing is caught in the seal.
- Use Smart Care and run a diagnostic and interpret codes with the Samsung Smart Washer/Dryer app.
Call support or professional support if a code persists after these steps or it indicates internal electrical or sensor failure.
Complete List of Samsung Washer Error Codes and Their Fixes
Common Samsung washer codes grouped by category are described below.
Samsung Washer Error Codes Starting with “E”
E1 – Water supply issue error means water is not properly entering the washer. This is due to blocked hoses, low pressure or kinked lines. Fix the washer by checking/straightening hoses, and ensuring taps are open. Inspect the pressure switch hose or sensor if water still will not fill.
E2 – Draining issue indicates the washer can not drain water fast enough. Check the drain hose for bends or obstructions. Then clean the pump filter if accessible.
E3 – Overflow means too much water is detected in the tub. This is caused by a blocked drain or faulty water inlet valve. Clear the drain path by clearing clogs and inspecting hoses.
E4 – Out of balance means the load is uneven thus preventing proper spin. Evenly redistribute clothes within the drum and restart the cycle.
E5 – Temperature sensor indicates a possible issue with the temperature sensing system. Professional sensor inspection or replacement are required.
Samsung Washer Codes Starting with “UE” / “DC” / “ND”
UE – Unbalanced load is solved by evenly redistributing clothes, and restarting. Ensure the washer is on a flat surface. Persistent imbalance requires suspension component checks.
DC – Door open means the washer thinks the door or lid is not securely closed. Check for obstructions and firmly close the door firmly.
ND – Not draining requires drain hose inspection, kinks or clogs removal, and cleaning the pump filter.
DE – Door error is similar to DC but specifically indicates a fault with the door/lid lock mechanism. Make sure nothing blocks the door or the door lock assembly might need service.
5E – The drainage issue is just like E2/ND, 5E. Check and clear any blockages in the drain system.
4E – Water supply error means water is not properly filling into the washer. Clean inlet screens and check for proper water pressure.
OE – Overflow error is linked to drainage blockages or inlet valve issues. Clear the drain path and inspect inlet components.
Samsung Washer Codes for Front Load Models
SUD – Excess suds means the washer has detected too many soap suds in the drum. It pause to let suds dissipate and then continue. Use less HE detergent and run a rinse cycle.
3E – Motor issue indicates an open/short circuit, hall/rotation sensor fault, or drive problem. Reduce load size, check motor wiring and connections, or go for professional inspection.
1E / 1C – Water level sensor where the washer can not correctly sense water level. Solutions include checking the pressure hose for kinks or blockages. Then replace a faulty sensor if cleaning and reconnections do not help.
9E1 / 9E2 – Power supply issue is voltage or power irregularity error. This means the washer is not receiving stable power i.e., too high/low or frequency issues. Ensure the washer is on its own dedicated circuit without extension cords. Then check household voltage stability. Persistent codes mean a control board fault.
Samsung Washer Codes for Top Load Models
UR – Unbalanced load means laundry is unevenly distributed during spinning. The washer tries to rebalance, then retries the spin. Redistribute clothes or call technicians for suspension components inspection.
LC – Leak sensor error signals a leak detected by internal moisture sensors. This is either a real leak or sensor misread. Check for water around the washer, tighten hose connections, and call for part replacement if required.
tE – Temperature sensor relates to a thermistor/temperature sensor fault. The washer can not correctly read water temperature. Run a diagnostic mode and check sensor wiring. Repeated tE errors require the sensor or wiring replacement.
bE – Motor issue means a motor speed sensor or motor control issue. Check for loose motor connections and reduce load. Call motor sensor or control board service if essential.
AE – Communication error indicates a communication failure between control boards or modules inside the washer. First try power-cycling the washer. Inspect wiring harnesses and connectors between control panel and main PCB if error persists.
Smart Washer App Error Codes (with Smart Care)
Smart Care feature runs a self-diagnostic on compatible washers. Then it uses the Samsung Smart Washer/Dryer app to interpret the results. Press the Smart Care button on the washer, then scan or manually enter the code into the app. The app explains what the code means and suggests troubleshooting steps.
